Product Engineer

ABOUT THE ROLE This is a product-focused engineering role at the intersection of customer discovery, end-to-end delivery, and engineering culture. You'll tackle mission-critical problems for energy retailers — turning complex domain challenges into intuitive, production-grade experiences — on a small, high-ownership team where your work directly moves the business forward. WHAT YOU'LL DO - Sit directly with customers to dissect problems and build product intuition that shapes engineering decisions. - Ship end-to-end solutions across the full stack, taking features from discovery all the way to production. - Use AI-native development tools (e.g., Cursor, Claude Code) as force multipliers to accelerate impact. - Own zero-to-one problems such as dunning workflows and customer portal re-engineering. - Prioritise ruthlessly — deciding what to build, what to skip, and when to kill initiatives. - Solve core energy retail challenges: billing, procurement, customer retention, and cost optimisation. - Shape engineering culture, tooling, and processes, and help raise the bar when hiring. WHAT WE'RE LOOKING FOR - 2+ years of software engineering experience shipping end-to-end, full-stack products to production. - A demonstrable track record of owning zero-to-one problems from discovery through production — we assess what you've built. - Strong full-stack capabilities and comfort owning entire systems independently. - Hands-on experience with AI-native development tools and the mindset to treat them as first-class instruments. - Experience solving billing, procurement, retention, or cost-optimisation problems in energy retail or a comparable consumer-facing domain. - Experience influencing engineering culture, tooling, and processes in an early-stage team. - High ownership, strong judgment, and genuine comfort operating in ambiguity at high velocity. - Bonus: contributions to core products in high-engineering-bar environments or notable open-source projects. COMPENSATION & BENEFITS Salary range: €80,000 – €120,000 per year. Visa sponsorship is not available. LOCATION On-site in Berlin, Germany. Remote applications are not considered for this role.
