Product Engineer

Department: Engineering

Location: Berlin

Employment Type: FullTime

About the Role

We're a small, mission-driven energy technology company building a full-stack platform that enables hardware manufacturers and energy providers to offer dynamic electricity plans to European households. Our team operates at the frontier of AI-assisted development, licensed electricity retail, and complex domain engineering — and we're looking for a product-focused engineer who thrives at the intersection of customer discovery, end-to-end delivery, and engineering culture.

This is a high-ownership, zero-to-one role. You'll work directly with customers, shape the product, and ship production-grade experiences that move the business in a measurable way.

What You'll Do

• Sit with customers to dissect problems and develop product intuition that drives engineering decisions.

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

• Use AI-native development tools (e.g., Claude Code, Cursor) as genuine force multipliers for your output.

• Own zero-to-one problems — think dunning workflows, customer portal re-engineering, billing infrastructure.

• Prioritize ruthlessly: decide what to build, what to skip, and when to kill an initiative.

• Solve core energy retail challenges: billing, procurement, customer retention, and cost optimization.

• Shape engineering culture, tooling, and processes, and help raise the bar as the team grows.

• Adapt quickly to new tools and methods, and bring teammates along to the frontier.

What We're Looking For

Must-haves:

• A track record of shipping real product work — we assess what you've built, not just years on a résumé.

• 2+ years of software engineering experience delivering end-to-end, full-stack products to production.

• Proven end-to-end ownership of zero-to-one problems, from discovery to live product.

• Hands-on experience with AI-native codebases and AI-assisted development tools.

• Comfort solving billing, procurement, customer retention, or cost-optimization problems in a consumer-facing or energy retail domain.

• Experience shaping engineering culture, tooling, and processes in a small or early-stage team.

• High ownership mindset with strong judgment and an ability to thrive in ambiguity.

Nice to have:

• Background in energy retail, utilities, or adjacent regulated industries.

• Contributions to high-engineering-bar environments or notable open-source projects.

• Experience operating with extreme ownership in a high-growth, fast-moving startup.

Compensation & Benefits

• Salary: €80,000 – €120,000 per year, depending on experience.

• Early-stage equity participation.

• Direct influence over product direction and engineering culture at a pivotal stage.

Location

• On-site in Berlin, Germany (Mitte area). Remote work is not available for this role.

• Visa sponsorship is not available — candidates must have existing authorization to work in Germany.
