About this role
Senior Product Manager | Hybrid, London |
We're looking for a Senior Product Manager to join a small, fast-moving team building an agentic AI platform for the built environment. The platform turns messy, document-heavy project data into evidenced, auditable findings, with every finding cited back to its source. It's already used by major UK infrastructure programmes and by organisations in insurance and financial services.
The company is entering a critical growth phase. This role is about making sure every client deployment strengthens the core product, so the business scales as a platform rather than as a bespoke services firm.
About the role
This is a hands-on product role. We're specifically looking for someone who understands how AI and retrieval systems work under the hood, not someone who manages them from a distance. You'll work closely with the CEO and engineering every day, so sound judgement, clear specs and the confidence to say no matter more here than process.
What you'll be doing
Owning the roadmap: turning strategy, client feedback and engineering constraints into a clear, prioritised planDeciding what gets built as core platform capability, what's delivered through configuration with partners, and what isn't built at allWriting specs in Linear that engineering can build from directlyBuilding a repeatable demo engine: sector templates, synthetic datasets and role-based viewsOwning the entity model as a core product capabilityExplaining to senior clients how the platform reaches its findings and why they can be trusted
What we're looking for
5+ years in B2B SaaS or enterprise product management, ideally taking complex platforms from proof of concept to enterprise rolloutHands-on understanding of retrieval, embeddings, vector search, chunking, context windows, and where models failExperience evaluating AI output, including building ground truth and spotting a model that's confidently wrongHeavy everyday use of AI to speed up your own product, research and design workStrong at reading a brief, finding the real need and coming back with a focused proposalThrives in a lean scale-up where priorities shift week to week, and owns their work without being chased
Nice to have
Experience in construction, infrastructure or complianceFamiliarity with ISO standards and regulatory frameworks
Why join
Real ownership of how a category-defining product takes shapeHard, interesting problems where trust is the productWork alongside the CEO and engineering daily, with your impact visible from day oneJoining at a critical growth phase, with clients already in place
If you want to build an AI product that serious organisations rely on, and you can explain exactly how it works, we'd love to hear from you
