We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.

We are looking for an experienced, hands-on Senior IT Systems Administrator to help manage, maintain, and improve our IT infrastructure across Spain and our global locations.

In this role, you will work with a broad range of technologies, including servers, virtualization, storage, and high-availability systems. You will play a key role in keeping our infrastructure reliable, secure, and scalable as Diamond Foundry continues to grow.

This is an exciting opportunity for someone who enjoys solving complex technical challenges, taking ownership of critical systems, and working closely with a global IT team. We value practical experience, problem-solving skills, and a willingness to learn and grow.
