Careers at office.one.
Want to keep IT running and help make it better? At Planetary Systems IT GmbH, people with different strengths work together. We’re looking for someone who thinks ahead, takes responsibility and wants to become a long-term member of our team.
IT Systems Administrator (all genders)
Do you enjoy understanding how systems work, finding root causes and putting practical solutions in place? At office.one, we support small and medium-sized businesses. We build long-term relationships with our customers, looking after workstations, Microsoft 365, servers, networks, backups and telephony.
We work with customer environments and our own infrastructure in Berlin data centres. Everyone has different strengths. You contribute your experience and work alongside colleagues whose skills complement yours.
Your responsibilities
- Windows Server and Active Directory: Maintain existing environments, manage users and permissions and help the team develop systems further.
- Microsoft 365, Exchange and Entra ID: Support setup, administration and migration so that email and collaboration work reliably.
- Networks and security: Set up networks, firewalls, Wi-Fi and secure access, and review existing configurations.
- Incident investigation: Find root causes systematically, document your work and explain next steps clearly to customers.
- Maintenance and backups: Check systems, updates and backups, with a focus on being able to restore an environment when it matters.
- Servers and virtual environments: Depending on your strengths, contribute to server, remote desktop and cloud environments and our own infrastructure.
- IT projects: Help with migrations, new workstations and infrastructure changes, including working with our customers’ software providers.
- PowerShell and automation: Simplify recurring tasks and help make processes clear and efficient.
- Hardware and on-site visits: Install server and network hardware and support customers on site when needed.
What you bring
- Practical experience administering and supporting IT systems.
- Knowledge of the technical areas above and a willingness to develop your strengths.
- A structured, independent approach focused on solutions.
- Curiosity about technology and an interest in understanding how things fit together.
- A sense of responsibility for customer systems and data.
- Enjoyment of teamwork and clear communication with customers and software providers.
You don’t need to be a specialist in every area. Your practical skills, how you work and how we complement one another matter more than a particular qualification.
How we work together
We are a technically focused team with a flat organisational structure. We share knowledge and work through difficult cases together. Our request intake process brings enquiries together so that we can assess urgency, find the right colleague and give tasks our full attention.
We’re looking for someone who thinks ahead, contributes ideas and wants to develop our work and customer relationships over the long term.
What you can expect
- A competitive salary.
- A friendly team and a flat organisational structure.
- A modern office near Berlin Südkreuz.
- A BVG public transport pass.
- Fresh fruit and our office dog.
