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).

Salary range: 80,000 to 120,000 EUR annually . Visa sponsorship is not available for this role.

Location

On-site in Berlin, Germany (Mitte), primarily five days per week. Remote applicants will not be considered.
