## Job description

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 seeking a highly experienced Senior IT Data Systems Administrator to architect, scale, and optimize our mission-critical IT infrastructure across Spain and our global locations. As a key technical lead, you will drive the stability, security, and operational excellence of our technology stack, balancing high-level infrastructure strategy with proactive systems management. The ideal candidate will bring deep expertise in clustering, high-availability environments, and enterprise networking, with solid experience in Linux systems and/or database administration. You will be instrumental in evolving our IT operations, providing architectural guidance, and collaborating cross-functionally to ensure our systems effectively support our rapid, large-scale growth.

## 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.

## Market Standing
- **Valuation**: Not disclosed (was a unicorn as of Series B). Revenue of $350M (annual) indicates strong growth.
- **Key Metric**: Annual Revenue: $350M (as of most recent data). Total Funding: ~$523M+ across multiple rounds (Series A, B, venture, debt).
- **Notable Investors**: Not explicitly listed in provided data, but funding history includes multiple institutional investors.
- **Growth Signals**: 5 years profitable; >90% global market share for large diamond wafers; headcount up 23.5% YoY (to 259 employees); active job postings up 54.2% YoY; building the largest solar + battery farm in Europe to power its Spain foundry.

## Competitive Advantages
- **Vertically integrated manufacturing**: Designs and builds its own reactor technology and runs all operations in-house, enabling rapid scaling and cost control.
- **First-mover in diamond wafers**: Claims >90% global market share for large single-crystal diamond wafers.
- **Extreme material advantage**: Diamond has 17,200x the semiconductor merit of silicon, offering a massive physics-based moat.
- **Green manufacturing**: Crystallizes greenhouse gas into diamond using zero-emission energy; byproducts are oxygen and water.
- **Profitability**: Rare for a hardware unicorn; has been profitable for 5 years.

## Strategic Focus
- **Near-term (2023+)**: Place a diamond behind every high-power chip, solving the thermal bottleneck for AI, EVs, and 5G/6G.
