For over 20 years, we have been a driving force in the expansion of renewable energies. We generate, store and deliver green energy around the globe - with wind, solar, biogas and hydrogen. Around 1,000 employees at various locations worldwide share our mission: to generate renewable energy sustainably for a livable earth.

Become a part of the ENERTRAG team at our location in Berlin as System Optimization Engineer (m/f/d) and let's advance the energy transition together.

Job Description

• You work with the System Planning team to perform techno-economic optimisation of Power-to-X projects, guided by specific project assumptions from the project developers.

• You develop and maintain software tools that support the optimisation efforts of ENERTRAG's System Planning team, ensuring they are effective and up to date.

• You ensure code versioning, collaboration, and management using Git, following best practices for branching, merging, and pull requests.

• You adhere to clean coding principles and participate in code reviews to maintain high software quality and consistency.

• You identify performance bottlenecks and optimize code to improve efficiency and scalability.

• You help to develop and extend new optimisation models, implementing them in a suitable programming language (e.g., Python).

• You prepare and present results in a clear and comprehensible manner, using visualisation techniques to enhance understanding.

• You write reports for internal reviews and decision-making, and conduct site inspections as needed.

Qualifications

• You have completed a degree in engineering, physics, mathematics, or a related field, with a specialization in applied mathematics (optimisation, operations research) or energy being a strong advantage.

• You have at least 4 years of hands-on experience in software development, with advanced proficiency in Python and Git.

• You have an understanding of energy economics and expertise in numerical optimisation (linear/non-linear programming).

• You have relevant professional experience in energy system modelling (capacity expansion and production-cost modelling), or have gained experience in energy system modelling and energy economics during post-graduate studies.

• You demonstrate a structured approach to work, strong teamwork abilities, and a high level of determination.

• Experience with open energy modelling tools for electricity generation and transmission expansion planning, such as PyPSA, Balmorel, or Calliope, is a plus.

• You are fluent in English and German a plus.
