Job description

We are currently looking for a System Administrator to join the team in Delft.

“A good sysadmin is somebody who automates their own job away"

S[&T] is a hi-tech company located in Delft that has been realising specialised software projects, services, and consultancy for (amongst others) the space industry for over twenty-five years.

Our three-person IRS (IT, Resources, and Security) team supports about 100 users in their day-to-day activities. Our userbase is growing fast, and with that comes the need to strengthen our infrastructure and support team.

We’re looking for a System Administrator with a broad range of skills and interests — someone who enjoys solving technical puzzles, improving systems, and keeping things running smoothly behind the scenes.

Main responsibilities

A bit about our setup

We have a heterogeneous environment, meaning there’s always something interesting to work on:

• Linux servers, and a mix of Linux / Windows / macOS laptops.
• A combination of local, co-located, and cloud servers.
• Extensive use of Docker containerisation across our infrastructure.
• Microsoft 365 for collaboration and document sharing.
• A variety of self-hosted services including Firewall/ switches/ WiFi, DHCP/DNS, printers, GitLab, NextCloud, Mantis, Redmine, Jenkins, Grafana, Matomo dashboards, and more.

We also support and advise internal project teams, each with their own specific hardware, software, and security needs. S[&T] is ISO9001 and ISO27001 certified, so information security is a top priority in everything we do.

You’ll be hands‑on with things like:

• Onboarding and offboarding colleagues and their hardware.
• Maintaining and monitoring our machines, networks, and licenses.
• Providing first‑line support — from fixing issues to setting up new workspaces.

And you’ll have a say in the bigger picture:

• Structurally addressing security concerns.
• (Re)designing our network architecture for better performance and security.
• Improving our helpdesk setup and efficiency.
• Developing tools and processes to automate workflows, monitoring, and alerting.
• Keeping up‑to‑date with new technologies, trends, and security advisories.

Requirements

We’d love to find someone who:

• Communicates clearly in English — written and spoken — and actually enjoys helping people.
• We aim to be an IT team that others feel comfortable approaching, not one they avoid!
• Is confident working with Linux‑based systems, and can write scripts or small tools to make everyday tasks more efficient.
• Has some experience (or willingness to learn) Windows, macOS, or M365 administration — versatility is more important than knowing everything upfront.
• Scripting knowledge or affinity would be a big plus!

What we offer

A friendly and collaborative team where you can have a real impact. We value people who take initiative, enjoy learning, and care about doing things the right way — both technically and professionally.
