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.
What you will do
- Build and run steady‑state and/or dynamic process simulations
- Integrate and adapt kinetic sub‑models within existing simulation environments
- Support early‑stage technical assessments of process concepts
- Assist with CAPEX/OPEX estimations using existing templates and assumptions
- Document assumptions, calculation paths and results in a clear, reproducible way
- Develop small programming tools or scripts for data handling, analysis or reporting
- Collaborate closely with engineering and lab teams – your results will be used further
Your profile
Must‑haves
- Enrolled in a Bachelor´s or Master’s program (chemical engineering, process engineering or similar)
- Mandatory internship as required by your study regulations
- Strong fundamentals in thermodynamics, reaction engineering/kinetics and separations
- Hands‑on experience with process simulation software (e.g. Aspen Plus/HYSYS, gPROMS)
- Python skills (NumPy, Pandas, plotting, basic automation)
- Analytical mindset, structured documentation and strong ownership of your tasks
Nice‑to‑haves
- Experience with dynamic simulation or model simplification
- Exposure to pilot‑scale or scale‑up topics
- Advanced AI skills, e.g. machine learning for parameter estimation, surrogate models, AI‑based optimization or automated analysis of large simulation datasets
- Curiosity to question models and assumptions, not just run them
Why us?
What we offer
- Close mentoring and clearly defined work packages with real impact
- Hands‑on work on actual engineering decisions, not academic exercises
- Modern tools and structured methods at the interface of simulation and engineering
- Insight into building sustainable chemical technologies up to pilot scale
- Option to continue with a Master’s thesis, if it’s a good fit
- Compensation according to company standards
About Us
Re-inventing chemistry
We develop disruptive chemical production processes by rethinking them from the atomic level all the way up to production scale.
We explore new chemistries by employing quantum-chemical simulations and transfer them into proprietary production technology.
Designing green processes
We develop & scale our new technologies based on renewable feedstocks & energy. From the very first steps in the development of a production process, we design it to enable closed carbon loops. Without compromise.
Defossilizing industries
With our climate-friendly chemical technologies we support industries in their net zero journey. Our first disruption is the proprietary C1 methanol technology. It unlocks green methanol production by overcoming long-standing challenges.
Working student essentials
What this Engineering working student role in Berlin means for you: the weekly-hours rules, the social-contribution perks, and what international students should check before applying.
Weekly hours
Working students may work up to 20 hours a week during the semester and full-time during the breaks. Staying within this keeps your student status and the Werkstudent benefits.
Working student rulesSocial contributions
Under the Werkstudentenprivileg you're exempt from health, care and unemployment insurance contributions — only pension insurance applies. That leaves more net pay than a regular job.
Check your insuranceInternational students
Non-EU students can work 140 full or 280 half days per year (raised from 120/240 in March 2024). A working student contract usually fits within this — confirm the exact limits printed on your residence permit.
