Mechanical Engineer

Founded by Jeff Holden — serial entrepreneur, ex-Amazon SVP and Uber’s first Chief Product Officer — the company has raised $250 million to date.

About the Role

We’re hiring a Mechanical Engineer to invent and build precision machinery for our Matter Compiler™ platform. You’ll turn demanding process requirements into automated machines, developing robotics and equipment for laser micromachining, deposition, fluid handling, and bonding.

You’ll own designs from early concepts through qualification and deployment, working alongside experienced engineers who will challenge your thinking and help you grow. Our in-house labs, machine shop, and Hybrid Fab give you the tools to build, test, and refine your ideas quickly and see your machines operate.

What You’ll Do

• Conceive, design, build, and qualify precision mechanisms, robotic axes, end effectors, and process hardware that enable new manufacturing capabilities.
• Work from first principles to solve coupled problems in mechanics, thermal behavior, and process physics, balancing precision, throughput, and reliability.
• Build and instrument prototypes, test your predictions, and investigate unexpected results. Carry what you learn through design improvements, qualification, and deployment.
• Work directly with electrical, software, and process engineers to integrate motion, sensing, controls, and mechanical hardware into complete machines.
• Produce clear CAD models, drawings, BOMs, and technical documentation that let others build, test, and maintain your designs.

What You’ll Need

• 3+ years designing and building complex mechanical or mechatronic systems.
• Strong engineering fundamentals and depth in at least one area such as machine design, precision engineering, thermal systems, fluids, or materials.
• Proficiency in CAD, mechanical drawings, and tolerancing, with practical knowledge of manufacturing processes.
• Hands-on experience fabricating, assembling, testing, and debugging hardware.
• Curiosity to explore unfamiliar technical problems, initiative to develop and test ideas, and willingness to seek feedback and follow through.
• B.S. in Mechanical Engineering or equivalent experience.

Bonus Points For

• Experience with high-vacuum equipment, laser or optical systems, precision robotics, or fluid and electrochemical systems.

The compensation for this position also includes equity and benefits.
