Product Engineer

About the Role

Join a small product engineering team at an early-stage energy technology company. You will work closely with customers and take full-stack solutions from discovery to production, helping simplify complex energy retail challenges through 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.

• Build and ship end-to-end features across the stack, from early discovery through production.

• Use AI-native development tools such as Claude Code or Cursor to accelerate development and expand your impact.

• Own zero-to-one initiatives, including customer payment and retention workflows and customer portal improvements.

• Make thoughtful decisions about what to build, defer, or stop, based on user and business needs.

• Address energy retail challenges such as billing, procurement, retention, and cost optimization.

• Help shape engineering culture, tools, and processes, and contribute to raising the team's technical bar.

What We're Looking For

• Typically 2 to 13 years of experience, with shipped product work and demonstrated technical ability valued more than résumé tenure.

• Strong full-stack skills and experience taking products from discovery through production.

• Fluency in German at C1 level or higher.

• Comfort using AI-native development tools as practical force multipliers.

• Evidence of exceptional technical ability through shipped projects, founding work, competitions, research, or comparable experience.

• Experience or strong interest in energy retail, including billing, procurement, customer retention, or cost optimization.

• High ownership, sound judgment, and comfort working in an ambiguous early-stage environment.
