Senior Product Engineer - Remote

Senior Product Engineer - Python / Product - UK, Remote Are you the kind of engineer who wants to design systems and shape products, not just pick up tickets? We’re hiring a Senior Product Engineer into a small, remote-first team that owns the “supply” side of a research platform. What you’ll be doing: This isn’t a “sit in the corner and code what you’re given” role. You’ll be: * Working hands-on across backend (Python) and frontend * Designing and explaining systems end-to-end (high-level diagrams, data flows, trade-offs) * Dealing with a large monolith that’s being modularised and improved * Solving core problems like: * how experts get onto the platform without long waitlists * how the right people see the right things at the right time * Pairing with Product to shape scope, priorities, and “what good looks like” * Using data and real user feedback to decide what to do next There’s a lot of thinking, not just implementing. What they care about: Yes, they want a strong Python engineer. But more importantly, they want someone who: * Thinks in systems, not just tickets * Can explain why they made certain technical decisions * Cares about business and customer impact, not just code quality * Pulls their weight in a small, high-trust, fully-remote team On the technical side, you’ll need: * Solid Python experience building non-trivial backend systems * Willingness to work full stack: * Vue is ideal, or strong modern JS framework + appetite to learn Vue * Comfort with cloud (GCP preferred; AWS is fine if fundamentals are strong) * Experience with larger/evolving codebases (monolith experience is a plus) * Ability to sketch and talk through system designs and trade-offs You don’t have to know everything. But you do need to be senior in Python and able to own problems end-to-end. Why this is worth a look: Most roles are “build this feature in your lane”. This isn’t. * You’ll have real ownership in a critical part of the platform (participant supply & distribution) * You’ll work across design, code, and product decisions – not just one layer * You’ll do it fully remote, anywhere in the UK, with a team that actually cares about engineering quality and people If you’re a strong Python engineer who enjoys full-stack work, systems design, and real product impact, this is the kind of role where you can actually shape how things work
