Job description

At IQM, we build world-leading quantum computers for the well-being of humankind. We design systems to tackle computational challenges beyond the practical limits of classical machines. Our work sits at the edge of science and engineering. It's complex, demanding, and deeply collaborative. We turn deep research into reliable, full-stack systems that drive discoveries in fields like medicine, energy, and technology, reshaping how the world computes.

Join the team that gives quantum a heartbeat.

The work

We're looking for a Senior System Administrator I to take ownership of key technical services and help keep our infrastructure running smoothly, securely and reliably.

In this role, you will take ownership of designated technical IT services, executing development tasks and contributing to project roadmap initiatives. You'll monitor and optimize uptime for internal and customer-facing production systems, plan and carry out upgrade and maintenance activities, and handle day-to-day administration of our IT infrastructure.

Documentation is a key part of this role — you'll keep records for IT systems and services accurate and current. You'll also analyze logs to catch critical alerts and resolve issues proactively, and collaborate with cross-functional teams and vendors to design and evolve infrastructure and applications.

What You’ll Actually Do

• Take ownership and responsibility of named technical IT services
• Execute IT development tasks and project roadmap initiatives
• Monitor and optimize uptime for internal and customer-facing production systems
• Plan & perform upgrade and maintenance activities
• Document IT systems and services, keeping records current

• Experience in systematic documentation practices
• Understanding of IT support principles, information security, and business continuity
• Exceptional problem-solving skills and ability to work under pressure
• Fluent in spoken and written English; cross-cultural communication skills
• Service-driven individual with a proactive, hands-on mindset for supporting stakeholders
• Ability to work on-site in a hybrid model, based in either our Espoo or Munich office

Additional Skills That Are Considered As An Asset

• Networking
• Scripting/programming
• Databases

Why IQM?

• Full-stack quantum computing: From quantum hardware to software layers and beyond, we build across the full-stack.
• High-performance playground: We aim high, and we know sustainable performance only works when life outside work does too—hybrid setups, flexible hours.
• Never the smartest: Expect to learn constantly. You won't always be the smartest person in the room, and that's the point.
• Approachable leadership: Flat hierarchy, direct access. Feel free to approach any leaders. They're friendlier than they look!
• The sweet spot: Big enough to matter. Small enough to move fast. Growing between a startup and a corporation. We’re in the phase where top performers get noticed.
• Bigger than IQM: Our people build know-how for the entire quantum ecosystem. We publish papers, run hackathons, and help shape a market that's still being defined.

The future of computing won’t build itself. You might be one of the few who do.
