Product Engineer

ABOUT THE ROLE This is a product-focused engineering role at a small, mission-driven energy tech company building AI-first software for electricity retailers across Europe. You will sit at the intersection of customer discovery and end-to-end delivery, turning complex energy domain challenges into intuitive, production-grade experiences that move the business forward. WHAT YOU'LL DO - Spend time with customers to uncover real problems and build product intuition that drives engineering decisions. - Ship full-stack features end-to-end, from discovery through production deployment. - Use AI-native development tools such as Claude Code and Cursor as force multipliers to accelerate delivery. - Own zero-to-one problems like dunning workflows, customer portal re-engineering, and other core energy retail challenges. - Decide what to build, what to skip, and when to kill initiatives based on strong judgment and ownership. - Tackle core energy retail domains including billing, procurement, customer retention, and cost optimization. - Help shape engineering culture, tooling, and processes, and raise the bar when recruiting. WHAT WE'RE LOOKING FOR - A strong track record of shipping real, end-to-end full-stack products; demonstrated work matters more than years on a resume. - Evidence of technical exceptionality through high-bar organizations, outstanding shipped projects, competitive programming, research, or founding experience. - Comfort owning the full stack and thriving in ambiguous, early-stage environments. - Fluency with AI-native development tools and a mindset that treats them as genuine productivity multipliers. - Experience at a seed to Series C startup and comfort with high-velocity ownership. - Interest or experience in energy retail problems such as billing, procurement, customer retention, or cost optimization. - Strong university background in a relevant field. - German fluency at a professional level (C1 or above). COMPENSATION & BENEFITS Salary range: 80,000 to 120,000 EUR annually. Visa sponsorship is not available for this role. LOCATION On-site in Berlin, Germany (Mitte), primarily five days per week. Remote applicants will not be considered.
