We’re looking for an engineer who understands the power grid — not just from a code perspective, but from a physics and systems point of view. You’ll help us simulate real-world electrical infrastructure, from transformers and overhead lines to fault conditions and power flow behaviours.

This is not a typical software developer role. You should be someone who enjoys working with simulation models, has a solid background in electrical engineering, and is confident turning physical behaviours into clean, maintainable C++ code.

Overview

We’re seeking an engineer who can translate physical electrical systems into robust software simulations, focusing on grid behaviour and reliable execution across platforms.

Responsibilities

• Develop and maintain C++-based simulation models for electrical grid behaviour
• Focus on short-circuit modelling, power flow, and grid stability
• Collaborate with domain experts to translate physical systems into simulation logic
• Work across Windows and Linux environments, depending on team/project
• Optionally contribute to tooling in Python and Qt framework
• Participate in technical discussions and knowledge sharing across a 60-person software team

What You Bring

• 4+ years of experience in C++ programming (ideally simulation-oriented)
• Background in electrical power systems or energy grid modelling
• Knowledge of short-circuit behaviour, transformer modelling, and system faults
• Strong mathematical thinking; ability to turn formulas and grid logic into software
• Comfortable working with both Windows and Linux environments
• Bonus: Experience with Python or GUI development using Qt
• German language is required (C1-C2)

Seniority

• Mid-Senior level

Employment type

• Full-time

Industry

• Services for Renewable Energy
