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 versatile Mechanical Engineer to provide comprehensive engineering support to the Systems & Automation Engineering group within our Advanced Factory environment. This role bridges the gap between mechanical design, automation, and industrial systems, helping to implement, optimize, and maintain advanced manufacturing equipment. The ideal candidate will combine solid engineering fundamentals with a hands-on approach, collaborating closely with automation engineers, controls specialists, and production teams to drive continuous improvement, ensure equipment reliability, and support the scaling of our high-tech factory operations.

Responsibilities

  • Systems Engineering Support: Assisting the Systems & Automation team in the design, integration, and deployment of advanced manufacturing equipment, factory automation systems, and electro-mechanical hardware.

  • Equipment Optimization & Troubleshooting: Diagnosing, analyzing, and resolving complex technical glitches or performance bottlenecks in active production lines, implementing modifications to improve equipment uptime and process efficiency.

  • Project Execution & Layout Design: Planning and executing equipment upgrade projects, utilizing CAD software (AutoCAD/SolidWorks) to update factory layouts, technical drawings, and system schematics as hardware evolves.

  • Cross-Functional Collaboration: Acting as a technical liaison between the automation group, maintenance technicians, and external vendors to ensure hardware installations align with operational needs and safety standards.

  • Documentation & Preventive Maintenance: Creating and updating Standard Operating Procedures (SOPs), maintenance plans, and technical documentation to ensure long-term reliability and standardized handling of automated equipment.

Requirements

  • Bachelor’s degree in Industrial Engineering, Mechanical Engineering, Mechatronics, or a closely related technical discipline.

  • 3 to 5 years of versatile engineering experience in high-tech manufacturing, automated assembly lines, or advanced industrial environments.

  • Solid multi-disciplinary baseline with familiarity in industrial automation components, low-voltage (LV) electrical installations, control systems, or pneumatic equipment.

  • Proficiency in CAD tools (such as AutoCAD or SolidWorks) for modifying layouts and mechanical/electrical schematics, alongside strong problem-solving skills.

  • Fluent in English and Spanish, with the communication skills needed to work effectively within an international, fast-paced engineering team.
