# Product Engineer (Mid-Level / Senior)

Join Sunsave, a fast-growing company revolutionizing the energy industry. As a Product Engineer or Senior Product Engineer, you'll own problems end to end, from shaping requirements to running solutions in production. You'll work closely with users, ship early, and build AI-native solutions. This is a full-stack role based in London, with a competitive salary, equity, private health insurance, and flexible working. Missions Own problems end to end, from shaping the requirements to running the solution in production. Work directly with users to shape the simplest solution, and say no when a requirement solves the wrong problem. Put first versions in front of real users fast, learn from real use, and drop what doesn't work. Profil recherché You've built and run production software at a fast-growing product company. We care more about what you've built, and how you think, than about your title. Builds with AI: You use coding agents (Claude Code, Cursor or similar) every day. You delegate the implementation, never the thinking, and you own every line you merge. Product-driven: You talk to users, challenge requirements, and can show a decision that changed what you built.
