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).
