About the Role
This is a founding engineering role at an early-stage B2B energy tech startup building an AI-powered platform that helps industrial companies optimise energy procurement and manage consumption in response to live market conditions. You'll join a small, ambitious team and have direct influence over product direction, technical architecture, and customer outcomes — from day one.
What You'll Do
-
Own the full product lifecycle from design through deployment, working closely with founders and customers.
-
Translate product objectives into concrete requirements through direct customer collaboration.
-
Design simple, iterative solutions to complex energy procurement and optimisation problems.
-
Build performant backend services for a data-intensive, real-time application.
-
Develop intuitive, elegant user interfaces for a complex decision-support system.
-
Train time-series forecasting models for power consumption and renewables production.
-
Develop linear optimisation algorithms that reduce customer energy costs.
-
Help shape the core tech stack and engineering culture of a fast-growing startup.
What We're Looking For
-
2+ years of software engineering experience delivering scalable web applications in a startup or high-intensity environment — this is a dealbreaker requirement.
-
Proven track record of delivering full product features end-to-end, independently, in close collaboration with customers.
-
Strong software engineering fundamentals: robust, maintainable, scalable web application development across backend and frontend.
-
Experience building backend services for data-intensive applications and frontend UIs for complex decision-support systems.
-
Hands-on experience or strong interest in time-series forecasting and/or linear optimisation.
-
Familiarity with PostgreSQL, TypeScript, React, and Python; FastAPI or Supabase experience is a bonus.
-
A genuine product mindset — you think about user impact, not just code quality.
-
Background as a generalist engineer, startup founder, or early CTO is a strong plus.
-
Curiosity about energy markets, complex data systems, and ambiguous, fast-moving problems.
Compensation & Benefits
-
Salary: €85,000 – €140,000 per year
-
Visa sponsorship: Not available
Location
Hybrid — primarily on-site in Munich, Bavaria, Germany, with flexibility for occasional remote work.
