On-site Product Engineer role in Berlin for a mission-driven energy tech startup; full-stack ownership from discovery to production, using AI-assisted development tools. 2+ years experience, salary €80-120k, no visa sponsorship.
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.
