Senior Product Engineer - Full Stack

Senior Product Engineer (hybrid/remote, you must be UK Based) We're looking for a Senior Product Engineer to join a small, high-trust engineering team building a next-generation platform while supporting an existing live product for enterprise clients. The role You'll own features end-to-end — from ambiguous problem to shipped solution — working directly with product, research and occasionally clients rather than building to fully specified tickets. Expect real ownership: shaping architecture, resolving ambiguous requirements, and being a source of judgement for the wider team. You'll also scope work clearly enough to hand to contractors when extra capacity is needed. Tech stack

• Backend: PHP/Laravel, microservices architecture, BFF (Backend for Frontend) pattern
• Frontend: React, SPAs
• Cloud: AWS (Lambda, Glue, S3, Bedrock, CloudFront)
• Data: Power BI, AWS data lake, HubSpot (CRM)
• Tooling: Jira, Confluence, GitHub
• Plus microservice-oriented architecture and document databases more broadly, with heavy use of AI-assisted coding, QA and CI/CD tooling (including Claude Code and Anthropic models) as standard practice What we're looking for
• Genuinely strong engineering ability across the stack — AI tools should accelerate a good engineer, not substitute for one
• Fluency with AI coding tools and an appetite to use them to ship faster, well-considered work
• Sound judgement on abstractions and system design, able to spot when AI-generated code is (or isn't) actually right
• A track record of owning larger, less-defined problems at whatever level that's occurred
• Comfortable with genuine ambiguity, curious about the product and users, not just the code
• Regtech/fintech experience preferred
• Strong communicator, self-managing, proactive — brings ideas rather than waiting for direction Practicalities
• UK-based, must be employable via PAYE
• Remote-friendly (current team is remote), though first day must be in person and some office attendance is encouraged, especially during probation
• No people management responsibilities
• Small team, minimal process, direct access to the people setting product direction Process: video interview → technical/skills assessment → final video interview
