About the role

We are looking for a highly independent Senior Product Manager to build a major new capability inside one of our live consumer web products, for an existing base of active users. You will be fully responsible for it end to end - researching what users actually need, defining the concept, producing the designs and prototypes yourself with AI tools, writing the backlog, shipping it with engineering, and then driving adoption and engagement after launch.

This is a high-ownership role suited for someone who thinks in products, not tickets. You will not be handed a spec, a designer, or a research team: you decide what to build, prove it with evidence, and get it live inside a product people already use every day - which means new work has to earn its place without degrading what already works.

Responsibilities

• Own the research behind what we build -user needs, behaviour in the current product, and the competitive landscape

• Turn findings into a clear, defensible product thesis the team can build from

• Produce high-fidelity, build-ready designs and clickable prototypes using AI design tools

• Define the end-to-end user journey, from first discovery of the feature to repeat use

• Keep new surfaces consistent with the existing product's design system and patterns

• Own a single prioritised backlog with clear sequencing, scope, and honest timelines

• Write developer-ready specs with acceptance criteria, edge cases, and measurable outcomes

• Run planning and delivery with the engineering team through to verified release

• Verify shipped work against spec, and reject what falls short of standard

• Define the metric tree for the feature - discovery, activation, task completion, repeat use

• Own the experiment roadmap: prioritize, instrument, read results, and act on them

• Build and maintain the dashboards you and the business make decisions from

• Collaborate with the Managing Director to align the roadmap with business goals

Qualifications

• 5+ years in product management on live consumer web products with a substantial active user base

• Proven track record shipping a significant new capability inside an existing product, not only standalone launches

• Demonstrated ability to run discovery yourself - user research, behavioural analysis, and competitor analysis

• Advanced, daily use of AI tools to produce high-fidelity, build-ready designs and clickable prototypes without a dedicated designer

• Strong quantitative skills: funnels, cohorts, and experiment design in a product analytics tool (Mixpanel, Amplitude, or equivalent), with working SQL

• Experience writing technical specs and running backlog and sprint delivery end to end (Jira, Linear, Notion, or equivalent)

• Working technical fluency: able to discuss implementation trade-offs with engineers credibly

• Evidence-driven - you can show the data or the test behind every product decision you defend

• Highly structured operator - builds repeatable research, spec, and experiment systems

• Comfortable being the only product person in the room, and making the call

• Clear, direct communicator who operates effectively in a remote environment
