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
