IT Administrator

HOW WE WORK

• Ownership from day one: IT support is yours. You decide how to organize it, with the backing of our CTO and Security team.
• Structure over firefighting: We'd rather you fix a problem once and automate or document it than fix it ten times. Building simple, self-service processes is part of the job.
• AI as a daily tool: We use AI tools like Claude across the company, including in IT. Whether it's drafting documentation, writing a small script, or troubleshooting an unusual error, we expect you to use AI actively to work faster and smarter.
• Close to Security: You'll work hand in hand with our Security & Compliance function. They define policies for devices and access; you put them into practice.

YOUR PROFILE

You'll be a great fit if you have:

• Fluent English.
• Hands-on experience in IT support or IT administration, ideally in a company running on Macs and SaaS tools
• Experience with an MDM and/or identity provider (JumpCloud, Jamf, Kandji, Okta, Google Workspace, or similar), or the demonstrated ability to learn tools like these quickly
• A service mindset. You're friendly, responsive, and patient, and you take pride in colleagues being unblocked quickly.
• A structured way of working. You keep track of open tickets, document what you do, and follow through.
• Comfort with light scripting or automation (shell, Python, or low-code tools), or the motivation to build this skill, ideally with AI assistance

Bonus points for:

• Experience administering Google Workspace and Slack
• Experience with hardware lifecycle management and IT asset inventory
• Basic networking knowledge (WiFi, VPN, DNS)
• Exposure to ISO 27001 or other security frameworks (access reviews, device compliance)
• Experience in a fast-growing startup environment

PRACTICAL DETAILS

This role is based in Berlin with regular presence in our office, since a core part of the job is hands-on: setting up devices, helping colleagues in person, and keeping office IT running. Outside of that, we're flexible about hours and remote days.

WHY US?

• Real impact: You'll build the IT function of a Series C company from the ground up and shape how 100 people work every day.
• Competitive compensation: A competitive salary above the market average.
• Top-notch equipment: A new MacBook Pro to ensure you have the best tools for the job.
• A great team: Regular company off-sites and team events that connect us as people, not just colleagues.
• Job security: A permanent contract in a stable, well-funded company.
