The Role

We're looking for a Product Engineer to help build our core consumer product. This is a full-stack role with Python at its core; you'll own problems end-to-end across APIs, async data pipelines, databases, integrations, infrastructure, and web/mobile when needed.

• Shape product ideas directly with the CTO and founders, making pragmatic technical decisions
• Use AI development tools extensively while owning the quality and correctness of everything you ship
• Help maintain a strongly typed, well-tested, well-observed codebase
• Take ownership beyond your immediate area: infra, database queries, CI/CD, mobile when needed

Requirements

• 5+ years of professional software engineering experience
• Excellent Python engineering skills and strong fundamentals
• Experience building asynchronous systems or data-processing workflows with significant concurrent/background work
• Strong experience shipping real products, ideally consumer-facing
• Demonstrated zero-to-one experience building new products or major features where the answers weren't already known
• Strong product xwzovoh judgment you care about the outcome, not just the implementation
• Comfortable working across a modern full-stack environment
• Experience with a modern frontend framework such as React
• Track record of taking loosely defined problems through to shipped solutions
• Clear communicator, comfortable collaborating with technical and non-technical teammates
• Comfortable operating in ambiguity and adapting as you learn
• In-office role, UK-based

• React Native / consumer mobile experience
• Experience in a regulated environment (healthcare, fintech)
