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.
