Job Description

Our Virtual Power Plant is a one-of-a-kind platform to provide grid services with sonnenBatterie-systems. By connecting household battery energy storage systems to our VPP, sonnen allows its customers to participate in ancillary services such as frequency control and demand response, further enabling the renewable energy revolution.

What you will do to help drive energy transition:

  • Contribute to a distributed Virtual Power Plant controlling tens of thousands of home battery systems across 8 countries in real time
  • Design, analyze, and improve algorithms for grid services — FCR, intraday trading, demand response, and spot optimization
  • Develop algorithms that optimize energy use within individual households, balancing self-consumption and cost savings under dynamic energy prices
  • Build and run simulations to model real battery behavior and validate algorithmic decisions
  • Analyze data streams to monitor system health and develop new signals that add value to the VPP
  • Implement protocols, backend services, and client features in a production Elixir/Rust codebase

What you will need on that journey:

  • Experience with Elixir, Rust, or Erlang — or strong motivation to learn. We hire at all experience levels.
  • Solid foundation in algorithms and mathematics; you enjoy working through problems that don't have obvious solutions
  • Comfortable reasoning about distributed systems, concurrency, or real-time constraints — or eager to develop that understanding
  • Experience with functional programming (Clojure, OCaml, Haskell, Scala) or Python is a plus
  • Fluent in English. German is a plus.
