Product Engineer

About the Role

We're a fast-moving, mission-driven energy technology company building the infrastructure that powers dynamic electricity plans for European households — and we're looking for a Product Engineer to sit at the intersection of customer discovery, end-to-end delivery, and engineering culture.

This is a high-ownership, zero-to-one role on a small team operating in a complex, regulated domain. You'll work directly with customers, shape what gets built, and ship production-grade solutions to real problems in energy retail — billing, procurement, customer retention, and cost optimization. We're an AI-first team and treat AI-native tooling as a core force multiplier, not an afterthought.

We're based in Berlin (Mitte), Germany. This role is fully on-site. Visa sponsorship is not available.

What You'll Do

• Sit with customers to dissect problems and develop product intuition that directly guides engineering decisions.
• Ship end-to-end solutions across the full stack — from discovery through to production.
• Use AI-native development tools (e.g., Claude Code, Cursor) to accelerate output and increase your impact.
• Own zero-to-one problems such as dunning workflows, customer portal re-engineering, and other core product surfaces.
• 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 as the team grows.
• Help recruit and raise the engineering bar across the team.
• Adapt quickly to new tools and methods, and bring the team along to the frontier.

What We're Looking For

Must-haves (dealbreakers):

• Demonstrated track record of owning zero-to-one problems from discovery to production — we assess what you've shipped, not just years on a résumé.
• 2+ years of software engineering experience delivering end-to-end, full-stack products to production.
• Hands-on experience with AI-native codebases and AI-assisted development tools (e.g., Claude Code, Cursor).

Strong requirements:

• Experience solving billing, procurement, customer retention, or cost-optimization problems in an energy retail or similar consumer-facing domain.
• Ability to ship end-to-end features that measurably reduce costs or improve customer experiences in production.
• Experience shaping engineering culture, tooling, and processes in a small or early-stage team.

Nice to have:

• Experience building or contributing to core products in high-engineering-bar environments or successful open-source projects.
• Comfort operating with extreme ownership and thriving in ambiguity within a high-growth environment.

Compensation & Benefits

• Salary: $80,000 – $120,000 per year (USD equivalent)
• High-impact role with significant scope to shape the product and engineering culture
• Work on mission-critical problems at the frontier of energy technology in Europe
• Small, senior team with strong ownership culture and fast feedback loops

Location

• Berlin, Germany (Mitte) — on-site
• Visa sponsorship is not available for this role
