Internship: Thermal Systems Engineer
At Entropic, we’re building software to decarbonize industrial heat, one of the biggest challenges in the energy transition, 20% of worldwide emissions. Engineers play a key role in this transition, but very often time is lost to manual and repetitive work. Our platform automates engineering for industrial energy projects, turning factory data into simulations and project proposals. Our platform makes engineers work 10X faster and lets them focus on what really matters: designing efficient and effective energy systems. We’re a growing, young and motivated team with backgrounds in energy, thermodynamics, and software. This is a chance to join a climate tech startup at the intersection of AI, software and engineering, already working with some of Europe’s largest factories.
The Opportunity
We’re looking for a Thermal Systems Engineer who loves turning physical systems into usable software models. You will work on the heart of our platform, developing and optimizing heat and energy models for industrial sites.
You will build models for technologies like heat pumps and thermal energy storage, capturing their physics and behavior under real-world conditions. You’ll then explore how to optimize their operation using energy prices and industrial load curves. When your model performs well, it will be implemented directly into our software, helping factories cut emissions and energy costs.
What You Will Do
Build physics-based simulation models for industrial heat technologies.
Develop simple, robust optimization for heat networks and operations.
Validate and benchmark models with supplier and site data (and stress-test edge cases).
Work with our product and development teams to integrate your models into the platform.
Improve internal docs, plots, and small tools that make other engineers faster.
Skills We Look For
Python: Comfortable writing clean, testable code.
Background: Chemical, Mechanical, or Process Engineering.
Experience: You’ve built a simulation or optimization project before (coursework or side project both count).
Mindset: You like turning physical models into simple and effective solutions. You care about impact, not just code or theory.
Nice to have: Familiarity with thermodynamics libraries, basic control/optimization and industrial data (timestamps, gaps, units).
Why Join Entropic?
Impact: Work on one of the most meaningful problems in climate tech and see your work in use at real factories.
Team: Join a young, ambitious, and growing team
Culture: We keep it fun. We often have drinks and have team activities about every other month (padel, karting, whatever gets us hyped).
