Product Engineer
Job description
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
