Your mission Why do an internship with us? You don’t want to run simulations just for slides – you want your work to influence real decisions? At C1 Green Chemicals, your models directly support process concepts that move from equations to pilot‑scale reality. What you build here has measurable impact on how sustainable chemical processes are designed. About us Cl Green Chemicals AG develops and scales new chemical processes from lab to pilot scale. Our teams span catalysis, synthesis, engineering and technical operations. Simulation plays a key role in deciding which technologies are built, tested and scaled – not as theory, but as a practical engineering tool. <h3>What you will do</h3><ul><li>Build and run steady‑state and/or dynamic process simulations</li><li>Integrate and adapt kinetic sub‑models within existing simulation environments</li><li>Support early‑stage technical assessments of process concepts</li><li>Assist with CAPEX/OPEX estimations using existing templates and assumptions</li><li>Document assumptions, calculation paths and results in a clear, reproducible way</li><li>Develop small programming tools or scripts for data handling, analysis or reporting</li><li>Collaborate closely with engineering and lab teams – your results will be used further</li></ul> Your profile Must‑haves<ul><li>Enrolled in a Bachelor´s or Master’s program (chemical engineering, process engineering or similar)</li><li>Mandatory internship as required by your study regulations</li><li>Strong fundamentals in thermodynamics, reaction engineering/kinetics and separations</li><li>Hands‑on experience with process simulation software (e.g. Aspen Plus/HYSYS, gPROMS)</li><li>Python skills (NumPy, Pandas, plotting, basic automation)</li><li>Analytical mindset, structured documentation and strong ownership of your tasks</li></ul>Nice‑to‑haves<ul><li>Experience with dynamic simulation or model simplification</li><li>Exposure to pilot‑scale or scale‑up topics</li><li>Advanced AI skills, e.g. machine learning for parameter estimation, surrogate models, AI‑based optimization or automated analysis of large simulation datasets</li><li>Curiosity to question models and assumptions, not just run them</li></ul> Why us? <h3>What we offer</h3><ul><li>Close mentoring and clearly defined work packages with real impact</li><li>Hands‑on work on actual engineering decisions, not academic exercises</li><li>Modern tools and structured methods at the interface of simulation and engineering</li><li>Insight into building sustainable chemical technologies up to pilot scale</li><li>Option to continue with a Master’s thesis, if it’s a good fit</li><li>Compensation according to company standards</li></ul>

C1 develops new, climate-friendly chemical production processes by rethinking chemical reactions from the atomic level all the way up to production scale. The first innovation to spin out of our quantum-chemistry platform is a novel, proprietary methanol catalysis. This groundbreaking technology disrupts a century old chemical production process and enables us to unlock non-fossil feedstocks for the production of green methanol. Green methanol will play a pivotal role in the defossilization of the carbon-based chemical industry and is poised to become the alternative fuel of choice for net-zero shipping. The market for green methanol is expected to grow to appr. $200 billion per year by 2050. The resulting CO2 saving potential of green methanol is several gigatons per year (several percentage points of current global CO2 emissions). Our aim is to realize as much of that potential as fast as possible.
