About the role

Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. 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.

Responsibilities

  • Manage, maintain, and improve critical IT infrastructure, ensuring reliability, performance, and availability across our locations.
  • Support and troubleshoot servers, virtualization platforms, storage, networking, and high-availability environments.
  • Maintain security, identity management, and access controls across enterprise systems.
  • Coordinate infrastructure upgrades, installations, migrations, hardware lifecycle activities, and vendor relationships.
  • Contribute to infrastructure improvements, technical documentation, and best practices to support our growing operations.

    • Requirements

  • 7+ years of experience in systems administration or IT infrastructure roles, preferably in complex enterprise environments. A relevant degree or equivalent practical experience is a plus.
  • Strong hands-on experience with enterprise servers, virtualization, and high-availability or clustering environments.
  • Experience administering Windows environments, Active Directory, and Remote Monitoring and Management (RMM) tools.
  • Strong troubleshooting and problem-solving skills, with the ability to independently manage complex infrastructure issues.
  • Professional proficiency in English and Spanish, with availability to work onsite in Zaragoza and travel within Spain when needed. Experience with Linux systems and/or database administration is desirable but not required.
    • Diamond Foundry believes in supporting our employees from the workplace to their personal and home life. We provide eligible employees with an opportunity to enroll in a variety of benefit programs, generally including health insurance, flexible spending accounts, retirement savings plans, life and disability insurance programs, and a number of programs that provide for both paid and unpaid time away from work.
