Senior Manager Product Planning in London

A decade of building – and we're still accelerating.

Flo is the world's #1 health & fitness app worldwide on a mission to build a better future for female health.

Now, we're building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.

As Senior Product Manager for Predictive Growth at Flo, you'll own Flo's predicted Lifetime Value (p LTV) platform across i OS, Android, and Web. p LTV is the shared signal behind UA bidding, budget allocation, creative-testing prioritisation, finance forecasting, and roadmap decisions across the organisation — making it one of the highest-leverage PM roles in growth.

You'll work with a team of data scientists, machine learning engineers, and data engineers running Flo's production p LTV models across short-horizon (intra-day) and long-horizon (M15+) predictions.

You'll also help scale Flo's in-house agentic experimentation system — already delivering 30%+ quality gains — and contribute to the next generation of Flo's marketing measurement stack, including Marketing Mix Modeling and incrementality testing.

Proven experience owning machine-learning or data-driven products in production — predictive scoring, propensity, ranking, forecasting, or similar data-rich products.

Strong fit for current Product Managers; Hands-on delivery instincts — equally comfortable in Jira (writing specs, defining epics, refining the sprint backlog, unblocking the team) as in strategic planning and stakeholder management.

Hands-on partnership with data science and machine-learning engineering teams — partnering on model evaluation, retraining cadence, feature decisions, and release discipline.

Strong analytical fluency — SQL proficiency, comfort interpreting model evaluation metrics, and the habit of interrogating performance at segment, cohort, and campaign level rather than blended aggregates.

Demonstrated ability to influence senior cross-functional stakeholders across marketing, finance, analytics, and engineering — translating technical model behaviour into commercial decisions.

Comfortable in fast-paced, ambiguous environments — balancing platform investments against fast-cycle experimentation, with shifting priorities and competing demands.

Working knowledge of mobile and web user acquisition — how bidding, attribution, and campaign optimisation actually work, including privacy frameworks such as SKAN/ATT or Privacy Sandbox.

Exposure to Marketing Mix Modeling, incrementality testing, holdout design, or causal inference techniques.

Owning Flo's p LTV product roadmap end-to-end across i OS, Android, and Web — driving accuracy improvements, expanding feature coverage, extending prediction horizons, and pushing p LTV into new decision domains (creative testing, product roadmap, pricing, hypothesis validation) alongside its existing UA and Finance use cases.

Partnering with data scientists and engineers on feature strategy — deciding which inputs the model consumes and ensuring those features are available reliably in production.

Operating rigorous release discipline — gated rollouts, shadow-mode evaluation, drift detection, automated retraining, and post-launch calibration — so production models stay accurate as data distributions and platform policies evolve.

Working closely with data scientists and analysts to investigate model quality issues — country-level miscalibration, cohort drift, signal anomalies — and feeding findings back into the next iteration.

Helping scale Flo's agentic ML experimentation system from hundreds toward thousands of model runs — compounding quality gains back into production.

Reporting model performance and strategic recommendations into monthly leadership reviews and quarterly investment decisions.
