Product Engineer

ABOUT THE ROLE Join a small, product-focused engineering team at an early-stage energy technology company. You will work directly with customers and own end-to-end solutions for energy retailers, turning complex operational needs into intuitive, production-ready products. WHAT YOU'LL DO - Work with customers to understand their problems and use those insights to guide product and engineering decisions. - Deliver full-stack features from discovery through production. - Use AI-native development tools to accelerate implementation and increase your impact. - Own zero-to-one projects, including customer payment and retention workflows and portal improvements. - Prioritize opportunities, make sound build-or-skip decisions, and stop initiatives when appropriate. - Build solutions for energy retail needs such as billing, procurement, customer retention, and cost optimization. - Help shape engineering practices, tooling, and team growth. WHAT WE'RE LOOKING FOR - Approximately 2 to 13 years of experience, with a strong record of shipping real products; exceptional project work and demonstrated technical ability matter more than tenure alone. - Hands-on full-stack engineering skills and experience delivering products end to end, from discovery to production. - Comfort with AI-native development tools such as Claude Code or Cursor. - Fluent German proficiency at C1 level or above. - High ownership, strong judgment, and the ability to work effectively in an ambiguous, early-stage environment. - Experience or a strong interest in energy retail, including billing, procurement, retention, or cost optimization. - A technical individual contributor profile, rather than a management-only role. COMPENSATION & BENEFITS Base salary: €80,000 to €120,000 annually. Visa sponsorship is not available. LOCATION On-site in Berlin, Germany, typically five days per week.
