Manager - Product Manager

About us Fospha is the marketing measurement platform trusted by the world’s leading consumer brands. Our Measurement OS unifies attribution, incrementality testing, and media mix modelling into a single operating system that helps marketing teams understand what’s really driving growth - and act on it with confidence. We’ve scaled globally over the past few years, with hundreds of top-tier clients in online retail, measuring many billions of dollars in media spend. Fospha has moved beyond our core measurement products into automation and incrementality, giving brands visibility into not just what happened, but executing on what happens next!

As a Product Manager, you'll own problems - not features. We work in lean, high-autonomy teams where people and agents collaborate to frame hypotheses, validate them, ship what works, and kill what doesn't. This role will primarily focus on data connector coverage for Fospha's principal platform partners - ensuring that we are always ahead of the curve on ingesting and providing measurement for their advertising products. You’ll work closely with platform partner technical teams, Fospha technical teams, and our commercial team to prioritise, build, and maintain the connectors that underpin everything Fospha does.

• Own connector coverage end-to-end: problem discovery through shipping, measuring, and iterating, framing problems as testable hypotheses and running efficient, fast experiments before committing engineering effort.
• Sequence the roadmap to balance short-term commercial impact (revenue, retention, churn) with long-term product vision.
• Shape the analysis rather than consume it: define the metrics and thresholds that drive decisions, not justify ones already made.
• Work cross-functionally with Data Science, Engineering, Design, and Commercial, and build direct technical relationships with principal platform partners so that API changes, launches, and deprecations are anticipated before they hit customers.
• Use AI tools daily (drafting, prototyping, analysis) and push the team to find new ways of working with them.

We hire for how you think and how you ship. Have commercial instinct: connect product work to revenue, retention, and growth, and ship something that unlocks value this quarter while building toward a bigger bet. LLMs embedded into PRD drafting, data exploration, prototyping, and analysis, not just brainstorming. Bonus for agentic workflows or MCP integrations. Shape the analysis and bias to action: name the metric, describe the hypothesis, explain the trade-offs, and ship imperfect over polished, with the judgement to know when good enough isn't. Thrive at the technical boundary: you've built or managed products on third-party APIs and understand that they change without notice, you're fluent in ad platform data (campaign hierarchies, attribution windows, conversion events; Commercial instinct, analytical rigour, and the drive to ship matter more than job title history.

Seek inclusion & diversity: we help colleagues in need and close loops, making sure our work is complete and has lasting impact. We care about the customer, feel their pain and love building product that solves their biggest problems.

Competitive salary and bonus. Opportunities for learning and development within the Blenheim Chalcot venture network. 25 days holiday, in addition to 8 bank holidays. Your birthday off! Daily office snacks and treats.
