About the Role
We're a pre-seed energy technology company on a mission to make energy free for European households. As a licensed electricity retailer, we build an AI-first, full-stack platform that enables hardware companies and energy providers to launch dynamic electricity plans — abstracting all legal and operational complexity into a clean API layer.
We're looking for a product-focused engineer who sits at the intersection of customer discovery, end-to-end delivery, and engineering culture. You'll own mission-critical problems for energy retailers and turn complex domain challenges into intuitive, production-grade experiences. This is an early-stage role with real ownership and outsized impact.
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, taking features from discovery all the way to production.
-
Leverage AI-native development tools (e.g., Claude Code, Cursor) as force multipliers to accelerate delivery and increase your impact.
-
Own zero-to-one problems — such as dunning workflows, customer portal re-engineering, and billing engine improvements.
-
Prioritize and curate the roadmap: decide what to build, what to skip, and when to kill an initiative.
-
Solve core energy retail challenges including billing, procurement, 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 the broader team along to the frontier.
What We're Looking For
Must-haves:
-
2+ years of software engineering experience delivering full-stack, end-to-end products to production.
-
A demonstrated track record of shipping real product work — we assess what you've built, not just your résumé.
-
Proven experience owning zero-to-one problems from discovery through to production.
-
Hands-on experience with AI-native codebases and AI-assisted development tools (e.g., Claude Code, Cursor).
-
Strong full-stack capabilities and comfort owning end-to-end systems.
-
High ownership mindset with the ability to thrive in ambiguity and early-stage environments.
Strongly preferred:
-
Experience solving billing, procurement, customer retention, or cost-optimization problems for an energy retailer or similar consumer-facing domain.
-
Experience shaping engineering culture, tooling, and processes on 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.
-
Background in energy technology, smart hardware integrations (e.g., EVs, heat pumps), or European energy markets.
Compensation & Benefits
-
Salary: €80,000 – €120,000 per year, depending on experience.
-
Early-stage equity opportunity on a mission-driven team.
-
Visa sponsorship: Not available — candidates must have the right to work in Germany.
