Product Engineer

About the Role

This is a product-focused engineering role at a fast-moving energy technology company, sitting at the intersection of customer discovery, full-stack delivery, and engineering culture. You will own mission-critical problems for energy retailers, turning complex domain challenges into intuitive, production-grade experiences. The team is small and mission-driven, so your work will have a direct and visible impact on the business.

What You'll Do

• Spend time with customers to dissect problems and build product intuition that directly shapes engineering decisions.

• Ship end-to-end solutions across the full stack, taking features from discovery through to production.

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

• Own zero-to-one problems including dunning workflows, customer portal re-engineering, and similar initiatives.

• Prioritize and curate the roadmap, deciding what to build, what to skip, and when to kill an initiative.

• Solve core energy retail problems across billing, procurement, customer retention, and cost optimization.

• Shape engineering culture, tooling, and processes, and help raise the bar when recruiting.

• Adapt quickly to new tools and methods, and bring the broader team along with you.

What We're Looking For

• A clear track record of shipping real, end-to-end full-stack products from discovery through production. We assess what you have built, not years on a resume.

• Strong full-stack capabilities with comfort owning systems end to end.

• Demonstrated technical exceptionality through high-bar organizations, standout shipped projects, competitions, research, founding work, or similar strong evidence.

• Fluency using AI-native development tools as genuine force multipliers.

• High ownership and strong judgment, with the ability to thrive in ambiguity and early-stage environments.

• Experience in or a strong interest in energy retail domains such as billing, procurement, customer retention, or cost optimization.

• Native or near-native German fluency (C1 or above) is required for this role.
