The Team
We are a start-up located in Trondheim, Norway. The goal of ThermoPhys is to make recent advances and developments from research on CCS, hydrogen and ammonia accessible and useful to the industry and accelerate the green transition.
A cloud-based software and APIs are currently under development. If you would like to contact us to try the software, to contribute or collaborate, the most efficient way to contact us is by using the mail address, or by using the contact form that both can be found at the bottom of this page.

Dr. Morten Hammer works full time in ThermoPhys, and is responsible for the technology development. He has a part time position as adjunct professor at NTNU and he has been the lead developer of the Thermotools repository since 2011. Morten has worked as a senior research scientist at SINTEF Energy and been part of the development of the flow assurance software called OLGA. He has decades of experience with thermodynamics, process engineering and CCS.

Dr. Øivind Wilhelmsen is the Chief Executive Officer of ThermoPhys. He has won several national and international research awards, co-authored more than 100 scientific articles and two text books on thermodynamics and hydrogen technology. He also works as Professor at NTNU, where he chairs the thermodynamics group.

Dr. Ailo Aasen is Chief Developer in ThermoPhys. He placed top five in the Norwegian Mathematics and Physics Olympiads (2009), received the Stubban prize for "promising young mathematicians" at NTNU (2014), and earned the EFCE Excellence Award in Thermodynamics and Transport Properties (2021) for his PhD. Ailo has a decade of experience as a research scientist in SINTEF Energy, solving challenges in CCS, ammonia and hydrogen technologies.
Open position as a fullstack developer in ThermoPhys
Full Stack Developer – Build software that decarbonizes the future
At ThermoPhys, we decode the physics and chemistry behind the green transition. Our models calculate thermophysical properties—thermodynamics, chemistry, and transport phenomena—with skill that’s earned us international recognition. These aren’t just academic exercises: they ensure the safety and reliability of technical solutions for clean energy, carbon capture, and beyond. Now, we’re scaling up.
In 2025, we need a talented Full Stack Developer to turn these state-of-the-art models into robust, user-friendly tools. This isn’t just another web dev role. You’ll be our go-to expert for bridging hardcore science with scalable software—owning the stack from API design to frontend polish.
What You’ll Contribute
- Python mastery – Bridge high-performance computational code with modern web stacks.
- API development (OpenAPI, FastAPI) – Build the pipelines that expose complex calculations to the world.
- Frontend development (React) – Design interfaces that make thermodynamics intuitive.
- Databases (PostgreSQL, MySQL) – Structure data for speed and reliability.
- Cloud deployment (Azure, Docker) – Containerize models for seamless scaling and absolute reproducibility in the cloud.
Why Join?
- Impact: Your work accelerates clean energy, carbon capture and storage, and beyond.
- Resourceful peers: Collaborate with award-winning scientists.
- Ownership: Competitive salary + equity. This isn’t a cog-in-the-machine role.
- Flexibility: A focus on results, not rigid schedules.
- Growth: Lead web development—we’ll rely on your expertise to set the standard.
Practical info
- Flexible employment: Full-time preferred, but we’ll consider part-time or summer roles for the right candidates.
- Workplace: Lerkendal, Trondheim.
- Deadline: Continuous review of applications.
