Job Description We are looking for a motivated Linux System Administrator with programming and automation skills to join our service team supporting the Flight Dynamics Division at the European Space Operations Centre (ESOC) in Darmstadt, Germany. The team provides engineering and operational support for the Flight Dynamics Platform, the mission-critical infrastructure used to prepare and operate multiple spacecraft missions. The role combines Linux system administration, infrastructure automation, platform engineering, IT security, end-user support, and software development within a operational environment. We are particularly looking for someone with a strong operational and system administration mindset who is also comfortable developing, testing and maintaining supporting tools, scripts, and system software components as needed. This is a customer-facing role requiring close day-to-day interaction with Flight Dynamics engineers. The successful candidate should be comfortable providing technical support, troubleshooting complex issues, and communicating effectively with both technical and non-technical stakeholders. The position is part of a highly skilled team of six engineers with complementary areas of expertise spanning Linux and FreeBSD system administration, software engineering, software build and configuration control, automation, storage technologies, networking, security, and operational support. Candidates are not expected to already master every technology listed in this profile. We welcome applications from both junior and experienced engineers: junior candidates should demonstrate strong technical foundations and a willingness to learn, while more experienced candidates are expected to contribute independently and bring deeper expertise in one or more relevant domains. Due to the operational nature of the role, regular on-site presence at the customer premises is required, particularly during testing, simulations, launches, and contingency activities. When operationally feasible, occasional teleworking near the customer site may be permitted. Candidates must also be eligible to obtain and maintain the required security and export control clearances, including ITAR/EIR-related compliance requirements where applicable.
