## 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 looking for an industrial equipment engineer to build, install, maintain and troubleshoot plasma reactors and other critical manufacturing equipment. You'll be working with an experienced team of process engineers, maintenance technicians locally and collaborating with mechanical, electrical, and software engineers in the US. Your goal will be to install new equipment in DF Spain, achieve maximum productivity for our production line through improving equipment capabilities and troubleshooting problems on the line.

## Responsibilities

- Installing, commissioning, upgrading, and maintaining plasma reactors (CVD tool) and other critical manufacturing equipment.
- Troubleshooting industrial control/electrical systems, including high-voltage power supplies, controllers, sensors, pumps, PLC’s, valves, and other devices.
- Tracking and reporting on equipment uptime/downtime, root cause analysis, overall equipment efficiency, mean time between failure and the like.
- Working with manufacturing technicians, plan and execute upgrades and retrofits to improve tool reliability and process capabilities.
- Writing procedures and checklists, assisting and training maintenance.

## Requirements

- Bachelor's degree in Electrical, Mechanical, Electronics Engineering or similar engineering discipline.
- 2+ years of hands-on engineering experience with manufacturing equipment.
- Ability in project planning and management, with the capacity to thrive in multidisciplinary teams to solve complex problems.
- Must be available to complete a training period in the United States. Additionally, this role involves ad-hoc short-term international travel to the U.S. to fulfill project needs.

- **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.
- **Mid-term (2033+)**: Deliver diamond semiconductors (transistors) that outperform silicon by orders of magnitude.
- **Operational**: Scaling production capacity in the US (Wenatchee, WA) and Spain (Trujillo), including building a massive solar+battery farm.
- **R&D**: Advancing heteroepitaxy and bonding processes in labs in the US and Germany.

## Why Work Here
