Your mission

C1 Green Chemicals AG develops and scales new chemical processes from the lab to pilot scale. Our value lies in research data, patents, and exclusive catalysis IP. A robust, sovereign IT setup is therefore mission‑critical.

Our research depends on stable and secure IT operations. In this role, you are responsible for day‑to‑day IT operations at C1 Green Chemicals AG – infrastructure, security, and devices.

• Ensure data sovereignty for sensitive research and IP data
• Microsoft 365 & Azure administration: tenant, Entra ID, applications, and operations
• Device management (Intune or equivalent) for laptops & smartphones (BYOD), clean onboarding/offboarding
• Set up and operate VPNs and secure remote access
• Linux server operations, including SLURM cluster for DFT compute (WEASEL/ORCA) and tested disaster recovery
• Continuous IT security monitoring, system hardening, access control, and audit‑grade traceability
• Prepare software and infrastructure cost comparisons for management decisions
• Act as the central IT point of contact across the company
• manage AI access (tokens, budgets) and serve as an internal AI point of contact
