C++ Software Developer - Aachen - Up to 90k - 80% Remote

About us

Join a specialised engineering team developing simulation software for the electric grid. This role is ideal for an electrical engineer or simulation-focused developer with strong C++ skills, who understands how to model physical systems like transformers, short circuits, and power lines — and enjoys converting technical knowledge into performant code.

We are particularly interested in candidates with experience in short circuit analysis, or a strong willingness to develop into that domain alongside our current subject matter expert.

Tasks

Key Responsibilities:

• Design and implement simulation software in C++ for power system analysis

• Model physical behaviours (e.g. short circuit, power flow, transformer behaviour) through code

• Contribute to simulations used by major utility and infrastructure clients

• Collaborate with domain experts and other engineers to refine algorithms and models

• Support both Windows and Linux development environments

• (Optional) Support GUI development or tooling in Python or Qt

Profile

Your Profile:

• Degree in Electrical Engineering, Power Systems, Applied Physics, or similar

• At least 4 years of professional experience in C++ development, ideally in a technical/simulation context

• Experience or interest in short circuit calculation or power system simulation

• Familiarity with grid infrastructure concepts (e.g. transformers, lines, fault behaviour)

• Comfortable working with both Windows and Linux toolchains

• Strong analytical thinking and system modelling mindset

• German language skills (B2+ preferred); English also acceptable if open to learning

We offer

What’s Offered:

• Flexible working (hybrid options)

• Supportive team with technical mentoring (especially for short circuit analysis)

• Stable team structure

• Transparent hiring process and long-term growth mindset
