About The Position

As a Mechanical Engineer at Atomic Semi, you'll design, iterate on, and build specialized equipment for semiconductor fabrication.
We're looking for hands-on engineers across various disciplines to design, iterate on, and build complex systems. Whether tackling heavy design challenges, integrating mechanical, optical, and electronic components, or automating production and manufacturing processes, our philosophy is to get things built and tested in days or weeks—not months—with a focus on viable solutions that meet real production needs.
We're hiring for a range of experience levels across several specialized teams:
The Positioning Team focuses on systems-level engineering, designing, prototyping, and building semiconductor fab equipment and subsystems related to lithography, motion, and metrology.
The Vacuum Team is responsible for designing, prototyping, validating, and scaling core semiconductor fabrication equipment. Tool families include Anneal, Deposition, Etch, and Supporting Infrastructure, with goals for each ranging from fundamental design to automation readiness to manufacturing scale-up.
The Packaging Team is responsible for designing, manufacturing, and overseeing the fabrication processes for semiconductor packaging devices. This position emphasizes designing, iterating on, and building specialized equipment for the manufacturing flow, such as laser ablation machines, reflow ovens, and automated metal plating facilities.
The Automation Team develops robotic automation systems to rapidly produce semiconductor packaging devices.
