Product Engineer

About the Role This is a product-focused engineering role at the intersection of customer discovery, full-stack delivery, and engineering culture. You'll work on 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 shapes the business. What You'll Do Sit with customers to dissect problems and develop product intuition that drives engineering decisions. Ship end-to-end features across the stack, taking work from discovery all the way to production. Leverage AI-native development tools to accelerate output and amplify individual impact. Own zero-to-one problems such as dunning workflows, customer portal re-engineering, and billing systems. Prioritise ruthlessly — deciding what to build, what to skip, and when to kill initiatives. Solve core energy retail challenges across billing, procurement, retention, and cost optimisation. Shape engineering culture, tooling, and processes, and help raise the hiring bar as the team grows. What We're Looking For 2+ years of software engineering experience delivering full-stack products end-to-end to production. A track record of owning zero-to-one problems from discovery through launch — we care about what you've shipped. Strong full-stack capabilities and comfort owning systems across the entire product surface. Hands-on experience with AI-native development tools (e.g., AI code assistants) as everyday force multipliers. Experience — or deep interest — in energy retail domains: billing, procurement, customer retention, or cost optimisation. Demonstrated ability to thrive in ambiguity and operate with extreme ownership in early-stage environments. Experience influencing engineering culture, tooling, or process in a small or growing team. Background in high-engineering-bar environments or meaningful open-source contributions is a plus. Compensation & Benefits Salary: €80,000 – €120,000 per year. Visa sponsorship is not available for this role. Location On-site in Berlin, Germany . Remote applicants cannot be considered for this position.
