IT Admin / System Administrator (m/f/d)
Our infrastructure is the backbone of everything we do at OKAPI:Orbits. As IT Administrator, you are the go-to technical expert for all IT matters in the company.

About the role
Our infrastructure is the backbone of everything we do at OKAPI:Orbits. As IT Administrator, you are the go-to technical expert for all IT matters in the company. No senior above you, no escalation path upward. You make independent decisions about how our infrastructure runs today and what it should look like tomorrow.
You take full ownership of our IT landscape: from on-premise servers and Docker infrastructure to laptops across all operating systems, Microsoft 365, network security, and long-term hardware and server planning. You'll be supported by a trainee (Auszubildender) who you mentor and develop as part of the role.

Key responsibilities
- Servers & Infrastructure: Operation and administration of our Linux servers (Ubuntu), including on-premise services like GitLab, SonarQube, and other tools running in Docker
- Strategic IT Planning: Long-term planning and evolution of our hardware and server infrastructure. You decide what we procure, replace, or rebuild and when.
- End Devices: Management and support of Windows, Linux, and macOS devices, from procurement to setup.
- Network & Security: Management of our network infrastructure, VPN configuration, and implementation of IT security policies
- Microsoft 365 & Intune: Administration of Azure AD, Exchange, Teams, SharePoint, and device management and policies via Microsoft Intune (MDM/MAM)
- Backup & Recovery: Development and maintenance of backup strategies and recovery processes
- Mentoring: Day-to-day technical guidance and development of our IT trainee
- Documentation: Thorough documentation of all systems, processes, and configurations so knowledge stays in the team
What you bring
Must have
- Degree, apprenticeship, or equivalent practical experience in IT (e.g. computer science, IT systems administration, or similar). We care about what you can do, not just how you got there.
- At least 2–3 years of experience in a comparable role. You know what you're doing and know when to ask questions.
- Ownership and decision-making confidence: You are the IT expert in the company, working without a technical manager above you. You make technical decisions independently and align with management on larger investments and budget questions, so you need to be able to justify decisions clearly and make a case for costs.
- Linux (preferably Ubuntu): server and desktop administration, shell scripting, package management
- Docker: hands-on experience operating and troubleshooting containerised applications
- Networking fundamentals: TCP/IP, DNS, DHCP, VPN configuration (e.g. WireGuard, OpenVPN)
- IT Security: solid understanding of security concepts, patch management, access controls, and system hardening
- Microsoft 365 & Intune: Azure AD, Exchange Online, Teams, licence and user management, and device management via Microsoft Intune across Windows, Linux, and macOS
- Hardware: experience with procurement, setup, and maintenance of end-user devices
- English: B2 or above. Our internal communication and documentation is in English.
Nice to have
- Experience with Terraform, Ansible, or other infrastructure-as-code tools
- Familiarity with Kubernetes or container orchestration
- Experience with SonarQube or similar code quality tooling
- Experience mentoring trainees or junior colleagues. You know how to pass on knowledge without doing everything yourself.
- German B2+. Useful for dealing with local vendors and authorities, but not a blocker.
- Background in a startup or scale-up environment where you shaped things, not just maintained them.
What we offer
A permanent contract, a real budget to learn, and a team that reviews its own benefits with the people who use them. Flexible core hours, 30 days of holiday, a subsidized pension, Hansefit, a BahnCard, and workation for more than a month a year.
Who you’ll work with
“You will own a slice of the platform end to end. Nobody here hands you a ticket and walks away.”

How we work
How we work
- Reality over abstractionReal catalogues, real physics, real orbital data. Demos run on the same engine that flies for customers.
- Clarity over decorationOperational tools earn their place by what they let you decide, not by what they look like at trade shows.
- Audit by defaultEvery decision is stamped, versioned, and exportable. There is no undocumented path.
- No conflict of interestWe do not operate satellites. Our only incentive is the accuracy of the assessment.
- Calm in the roomOperations work is high-stakes. The platform lowers the stress level, not amplifies it.
