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. Measurement will always be at our core – but we’re now expanding who we serve and how, opening up entirely new parts of the commerce ecosystem. The roadmap from here is the most ambitious in the company’s history, and we’re hiring the people who’ll make it real. The Role 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. You'll work alongside an expert group of technical leaders and AI agents as part of our AI‑first operating model. 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. Every new ad format, API change, or product launch from platforms like TikTok, Google, Meta, Snap, Pinterest, and Amazon needs to be reflected in Fospha before our customers or competitors notice the gap. This is a technically grounded, client and partner‑facing role. 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. Key Responsibilities

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.

What Are We Looking For You should apply if you:

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. Default to hypotheses, not feature requests: frame problems as beliefs to test, design experiments to validate them, and treat invalidation as a win. Are AI‑fluent in practice: 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 judgment 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; ideally hands‑on with two or more of Meta, Google, TikTok, Amazon, or Snap Marketing APIs), and you can have productive engineering conversations about ingestion, rate limiting, and error handling without writing the code yourself.

You don’t have to be a career PM. Some of the strongest product people here came from engineering, customer success, or domain expertise and discovered that they think in products. Commercial instinct, analytical rigour, and the drive to ship matter more than job title history. Our Values and Principles

Seek inclusion & diversity: we create an environment where everyone feels welcome, and people are encouraged to speak and be heard.
