We've priced over 1 trillion programmatic auctions, we're currently ranked #5 globally in Prebid Analytics Adapter Rankings, and growing.<br><br></div>
<div><strong>The problem we're solving<br></strong><br>Digital publishers and advertisers leave significant revenue on the table because ad sales are still largely manual, static, or rule-based. The reality is every campaign is unique, but most ad campaign management systems lack the intelligence to evaluate context, demand, and deal potential in real time.</div>
<div><br>As a founding member of AgenticAdvertising.org, we're building the next generation of autonomous advertising infrastructure.</div>
<div>
<div><strong><br>Who You Are<br></strong></div>
<ul>
<li>An experienced engineering manager who has stayed close to the work: you can review a pipeline design, challenge a modelling decision, and unblock an engineer without taking the keyboard.</li>
<li>A pragmatic technical mindset: you know when to invest in data platform work, when a simpler solution is better, and how to balance reliability, latency, cost, and delivery speed.</li>
<li>You communicate well in writing and conversation with engineers, product, and non-technical stakeholders — and you can turn ambiguous product asks into a clear, sequenced plan.</li>
<li>You grow engineers: through feedback, delegation, and raising the bar on quality rather than doing the work yourself.</li>
<li>You take ownership of outcomes, not just output — if the data platform has a problem, it's your problem.<strong><br></strong></li>
</ul>
<div><strong>What You'll Work On<br></strong></div>
<ul>
<li>Lead the data engineering team: line management, coaching, performance, and hiring as the team grows</li>
<li>Own the data platform roadmap: pipeline improvements, orchestration, tooling, data quality, and cost/reliability work — you decide what gets built and when, and you make the case for it</li>
<li>Partner with product on feature scope: translate product requirements into data deliverables, commit the team to realistic plans, and deliver against them</li>
<li>Set and uphold the team's engineering standards: schema management, validation, lineage, SLAs, and incident response</li>
<li>Guide the design of high-volume batch and streaming pipelines powering agentic AI features and core product workflows</li>
<li>Enable AI/ML workflows with robust datasets for training, evaluation, feature generation, and feedback loops from production agents</li>
<li>Stay hands-on where it counts: design reviews, architectural decisions, prototyping, and occasionally shipping code to keep your judgement sharp</li>
</ul>
<strong>What We're Looking For<br></strong><br>We're looking for an experienced engineering manager who has led data teams on production systems and enjoys solving practical problems with AI.</div>
<div><br>You likely have:</div>
<div>
<ul>
<li>Experience managing data or data platform engineers with direct accountability for delivery, quality, and team health</li>
<li>Recent hands-on experience with the modern data stack: strong SQL + Python, and working fluency with tools like Spark, Airflow/Dagster, dbt, Kafka/queues, and warehouse/lakehouse patterns</li>
<li>A track record of owning a technical roadmap: identifying platform investments (orchestration, tooling, data quality), prioritising them against product work, and shipping them</li>
<li>Experience partnering with product managers: scoping, estimating, sequencing, and communicating trade-offs clearly</li>
<li>Operational maturity for production data systems on AWS: monitoring, incident response, and security considerations (PII, access control, encryption, auditability)</li>
<li>Familiarity with data for AI/ML and agentic systems: feature pipelines, evaluation datasets, grounding/citations inputs, and feedback capture from agent outcomes</li>
<li>Experience hiring and growing engineers, ideally in a distributed or async-first team</li>
</ul>
<strong>Who This Role Will Suit<br></strong><br>
<div>This role suits folks who like a mix of autonomy and collaboration, and who are comfortable working in an environment that's still evolving.</div>
<div>&nbsp;</div>
<div>We're a distributed team with a growing engineering presence in UK, Europe, and India, so comfort with async collaboration and clear written communication is important.<br><br>We use agentic coding tools heavily (e.g.Claude Code) to plan, scaffold, refactor, and debug production code, while maintaining strong engineering judgment and ownership of outcomes.</div>
</div>
<div><br>Bonus (not required):</div>
<ul>
<li>Experience with AdTech or other high volume real-time systems</li>

Engineering Manager - Data

<html><head></head><body><div>
<div>Location: Remote (UK / EMEA)</div>
<div>Type: Full-time, permanent</div>
<div>Reports to: Product Lead</div>
<h1><br>About pubX</h1>
<div>pubX builds next-generation agentic advertising infrastructure. Our AI makes real-time, revenue-critical decisions for digital publishers and advertisers. We've priced over 1 trillion programmatic auctions, we're ranked #5 globally in the Prebid Analytics Adapter Rankings, and we're a founding member of AgenticAdvertising.org.</div>
<div>&nbsp;</div>
<h1>The Problem We're Solving</h1>
<div>Publishers and advertisers leave significant revenue on the table because ad sales are still largely manual, static, or rule-based. Every campaign is unique, but most campaign management systems lack the intelligence to evaluate context, demand, and deal potential in real time.</div>
<h1><br>Why This Role Exists</h1>
<div>We're building the infrastructure for agentic advertising: AI agents that sit on both sides of a media transaction, taking a buyer's brief through to a live, publisher-approved campaign with minimal manual work.</div>
<div>This role exists to take real ownership of a piece of that system. You'll take a defined area from discovery through delivery and iteration, with clear accountability for the roadmap decisions, the trade-offs, and whether it actually works once it's live.</div>
<h1><br>The Role</h1>
<div>You'll own a defined area of Agentic Advertising end-to-end: framing the problem, scoping the MVP, working directly with engineering to build it, and staying accountable for it once it's live. You'll be in the detail with engineering day-to-day.</div>
<div>This work is already running with real advertisers and publishers, and the standards underneath it are still being written. Cycles are short and what you ship reaches live campaigns quickly.</div>
<div>You'll work closely with the rest of the product team, engineering, and commercial teams.</div>
<h1><br>What You'll Do</h1>
<div>
<ul>
<li>Lead end-to-end discovery and delivery for your area of Agentic Advertising</li>
<li>Frame problems clearly and validate them through user research and data</li>
<li>Define MVP scope, success criteria, and iteration plans</li>
<li>Prioritise work based on impact, effort, and learning, and be explicit about what you're not doing</li>
<li>Work day-to-day with engineering to unblock delivery</li>
<li>Use AI to increase the speed and quality of your own discovery and delivery work, while holding a high bar for accuracy and data sensitivity</li>
<li>Support launches and adoption with Sales and Customer Success</li>
</ul>
</div>
<div>&nbsp;</div>
<h1>What Success Looks Like (First 6 Months)</h1>
<div>
<ul>
<li>At least one meaningful capability shipped end-to-end from discovery through launch, with instrumentation in place and at least one change made on the back of what it told you</li>
<li>A focused, outcome-driven roadmap for your area: priorities, trade-offs, and what you're deliberately not doing and the reasons why</li>
<li>Engineering trusts you to scope your area's work accurately</li>
<li>Strong working relationships across product, engineering, and commercial</li>
</ul>
</div>
<div>&nbsp;</div>
<h1>What We're Looking For</h1>
<h2>Must-have</h2>
<div>
<ul>
<li>5+ years product management experience shipping B2B SaaS products, where you defined the problems worth solving rather than delivering against a roadmap set elsewhere</li>
<li>Experience in AdTech / programmatic, ideally with exposure to the buy side, sell side, or both</li>
<li>Experience running discovery and scoping MVPs under real constraints, ideally without much supporting infrastructure (design, research, data) to lean on</li>
<li>Excellent written and verbal communication — able to make a case to technical and non-technical audiences without losing the nuance</li>
<li>Comfort using data to define and evaluate success, and knowing when the data doesn't answer the question</li>
<li>Pragmatic product judgment and a bias toward outcomes</li>
<li>A demonstrated habit of using AI to improve day-to-day product work</li>
</ul>
</div>
<div>&nbsp;</div>
<h2>Nice-to-have</h2>
<div>
<ul>
<li>Experience with technical products involving APIs, agents, or data integrations</li>
<li>Familiarity with agent protocols or agentic workflows (AdCP or similar)</li>
<li>Experience shipping AI-powered features or products</li>
</ul>
</div>
<div>&nbsp;</div>
<h1>How We Hire</h1>
<div>1. CV &amp; profile review<br>&nbsp;We look at relevant experience and background to confirm fit before moving forward.</div>
<div>2. Initial chat (45 mins)<br>&nbsp;A conversation about motivation, role fit, and a deeper dive into your experience.</div>
<div>3. Live task interview (60 mins)<br>&nbsp;A live exercise testing product thinking and problem-solving in practice, not just in theory.</div>
<div>4. Final interview (60 mins)<br>&nbsp;A behavioural interview covering how you think, how you work, your technical and commercial judgement, and whether we're the right fit for each other.</div>
<h1><br>Compensation &amp; Benefits</h1>
<div>Competitive salary, equity, and benefits. Leveling aligned with our product organisation framework.</div>

Senior Product Manager (UK/EU)

<html><head></head><body><h2>Why This Role Exists</h2>
<p style="text-align: justify;">pubX is transitioning from an AI-powered yield optimization tool into the first truly agentic advertising marketplace — where buying agents and sales agents negotiate deals autonomously, in real time, on behalf of advertisers and publishers. We've priced over 1 trillion programmatic auctions, we're ranked #5 globally in Prebid Analytics Adapter Rankings, and as a founding member of AgenticAdvertising.org, we're helping define the protocols and standards for this new era.</p>
<p style="text-align: justify;">We need a commercially relentless Business Development Director to drive new publisher sales in North America. Your mission: bring Tier 1 publishers and Jounce Bellwether-caliber partners into the pubX ecosystem — ensuring the highest-quality supply fuels our agentic marketplace and delivers premium revenue for the publishers we work with.</p>
<h2>&nbsp;</h2>
<h2>The Problem We're Solving</h2>
<p style="text-align: justify;">Programmatic advertising is stuck. Publishers manage fragmented demand across dozens of partners with manual rules and static pricing. Advertisers struggle to find and activate premium inventory without endless deal setup and troubleshooting. Both sides lose value to a system built on handoffs, friction, and guesswork.</p>
<div style="text-align: justify;">pubX is building the first truly agentic advertising marketplace — where autonomous buying agents and selling agents negotiate directly, creating deals that traditional programmatic can't match. For publishers, that means better CPMs, stronger fill rates, and the ability to transact first-party data at premium rates. For advertisers, it means exclusive inventory access and quality signals unavailable elsewhere. Both sides get full transparency.</div>
<div style="text-align: justify;"><br>As a founding member of AgenticAdvertising.org, we're building the next generation of autonomous advertising infrastructure.</div>
<h2>&nbsp;</h2>
<h2>pubX at a Glance</h2>
<p style="text-align: justify;">1 Trillion+ auctions priced · 400 Billion+ annual auctions processed · #5 globally in Prebid Analytics Adapter Rankings · Founding member of AgenticAdvertising.org · Fully remote, async-first culture · Profitable core product with accelerating growth.</p>
<h2>&nbsp;</h2>
<h2>The Role</h2>
<div>
<div style="text-align: justify;">As Business Development Director, you'll own the full new-business supply-side pipeline for publisher partnerships in North America. You'll identify, pitch, negotiate, and close deals with Tier 1 publishers, media owners, and strategic supply-ecosystem partners. You'll be a pubX evangelist, translating the power of agentic advertising and AI-driven yield optimization into a commercial story that resonates with senior publisher leadership.</div>
<div style="text-align: justify;">&nbsp;</div>
<div style="text-align: justify;">This isn't account management or renewals. This is new business. You'll hunt, prospect, and close — working with some of the most sophisticated digital media businesses in the world with pubX’s heritage and brand as a publisher first tech builder of excellence behind you.</div>
<div>&nbsp;</div>
</div>
<h3>What You’ll Do</h3>
<ul>
<li>Grow pubX's publisher portfolio by prospecting and closing new partnerships with Tier 1 and Jounce Bellwether-caliber publishers, media owners, and digital properties across North America</li>
<li>Build and manage a high-velocity pipeline of publisher opportunities through outbound prospecting via phone, email, LinkedIn, industry events, virtual meetings, and onsite presentations</li>
<li>Act as the primary pubX evangelist for agentic advertising — articulating how autonomous sales agents, AI-driven yield optimization, and first-party data monetization create differentiated revenue for publishers</li>
<li>Close high-value deals and negotiate commercial terms that align publisher incentives with pubX's growth objectives, working collaboratively with the North American President and wider leadership tea</li>
<li>Identify areas of opportunity and industry trends — including shifts in supply path optimization, Prebid adoption, privacy regulation, and agentic AI — to position pubX's offerings ahead of the market</li>
<li>Demonstrate deep product knowledge of pubX's Bid Intelligence, agentic marketplace, and first-party data capabilities to senior publisher stakeholders (CROs, SVPs of Programmatic, Heads of Ad Tech)</li>
<li>Represent pubX at key industry events (POSSIBLE, Digiday, Beeler Tech, Prebid Ascent, AdExchanger, Programmatic I/O, and others) to build visibility, generate leads, and cultivate relationships</li>
<li>Maintain accurate pipeline records and communicate goals, forecasts, and results to leadership with clear, data-driven reporting</li>
<li>Collaborate cross-functionally with Product, Engineering, and Customer Success to feed publisher insights into the roadmap and ensure seamless onboarding of new partners</li>
</ul>
<h3>What We’re Looking For</h3>
<div>We're looking for an experienced, commercially driven professional with a hunter mentality who has deep relationships across the publisher and programmatic ecosystem.</div>
<ul>
<li>7+ years of experience in publisher development, business development, or new-business sales within AdTech, programmatic advertising, or the broader digital media ecosystem</li>
<li>An established network of publisher and media owner contacts — particularly among Tier 1 properties and Jounce Bellwether-recognized portfolios (e.g., publishers like Dotdash Meredith, Fandom, Raptive, Yahoo, Paramount, and similar-scale operations)#</li>
<li>Strong understanding of the programmatic supply chain — header bidding (Prebid), supply path optimization, bid-stream dynamics, SSP/DSP relationships, and publisher yield economics</li>
<li>Fluency in first-party data, identity, and privacy — you understand why publisher first-party data is increasingly valuable and can articulate how agentic AI unlocks its potential</li>
<li>Proven track record of closing high-value deals with complex, multi-stakeholder publisher organizations, including the ability to sell into CRO, SVP, and VP-level decision makers</li>
<li>Entrepreneurial mindset — you're comfortable building the playbook, not just following one. You've thrived in scaling environments where you need to be resourceful, self-directed, and creative</li>
<li>Exceptional communication skills — you can deliver a compelling in-person pitch to a room of senior publisher executives as easily as you write a sharp cold email</li>
<li>Comfort with AI and emerging technology — you don't need to write code, but you should be excited by agentic AI and able to credibly discuss how autonomous agents are reshaping programmatic advertising</li>
<li>Curiosity and creative thinking around new revenue opportunities — uncovering new revenue streams and opportunities whilst building publisher relationships, and turning those ideas into product.</li>
<li>Bonus (Not Required): Experience selling into publishers already recognized by Jounce Media as Bellwether portfolios. Knowledge of the Advertising Context Protocol (AdCP) or involvement in AgenticAdvertising.org initiatives. Previous work in a startup or high-growth AdTech environment. Familiarity with pubX's existing publisher partners or the Prebid ecosystem.</li>
</ul>
<h3>Who This Role Will Suit</h3>
<p>This role suits commercial leaders who have a genuine passion for publisher technology and the open web. You believe publishers deserve better monetization tools than the industry has given them, and you're energized by the idea of bringing a genuinely differentiated product — agentic advertising — to market.</p>
<div>You like a mix of strategic thinking and hands-on execution. You're as comfortable mapping out a quarterly territory plan as you are picking up the phone to cold-call a publisher CRO. You're motivated by the early-stage opportunity: meaningful equity, a seat at the leadership table, and the chance to shape how pubX grows across North America.</div>
<div>&nbsp;</div>
<div>We're a distributed team that works asynchronously, so comfort with remote collaboration and clear written communication is important. We also use AI tools extensively across the business — including agentic coding tools like Cursor and Claude Code — and expect commercial team members to embrace AI-native workflows.</div>
<div>&nbsp;</div>
<h3>Interview Process</h3>
<p>Our process is designed to be practical and respectful of your time.</p>
<div>
<ol>
<li>CV &amp; Profile Review: Relevant experience, publisher network, and commercial track record</li>
<li>Cultural Fit (30 mins): Motivation, role fit, and alignment with pubX's mission and agentic vision</li>
<li>Commercial Deep-Dive (60 mins): Pipeline strategy, publisher engagement scenarios, and deal-closing approach</li>
<li>Leadership Conversation (45 mins): Meet the North American President and wider leadership team</li>
</ol>
</div>
<h2>&nbsp;</h2>
<h2>What We Offer</h2>
<div>
<div>
<div>What We Offer</div>
<ul>
<li><strong>Competitive Salary + Stock option bonus</strong> - Early-stage equity in a fast-growing company</li>
