About Atomic Semi
Atomic Semi is building a small, fast semiconductor fab.
It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.
We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.
Smaller is better. Faster is better. Building it ourselves is better.
We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.
Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.
About the team
The packaging engineering team is responsible for developing a novel method to rapidly produce semiconductor packaging devices. We design, prototype, build our own fabrication equipment, and develop novel processes. We have assembled a specialized team skilled in machine design, physics, and chemistry to achieve this.
About the role
As a Mechatronics Engineer at Atomic Semi, you'll design and iterate on specialized equipment for semiconductor packaging fabrication.
We're looking for a hands-on engineer with experience building complete systems (like laser machines, reflow soldering oven, or 3D printers) who can integrate mechanical, optical, and electronic components.
The ideal candidate thinks from first principles, moves quickly from concept to functional prototype, and has experience with optomechanical design. Our philosophy is to get things built/tested in days or weeks, not months, with a focus on viable solutions that meet real production needs.
Responsibilities
Design and iterate on machines and subsystems for semiconductor packaging fabrication
Create mechanical designs including frames, components, and assemblies
Integrate optical and electrical components in system assembly, including wiring, optics alignment, and electronics
Collaborate with cross-functional teams to continuously improve fabrication processes and equipment
Source components and materials while working with vendors to meet project specifications
Required Experience
Proven experience in mechanical and electromechanical system design
Hands-on experience building, prototyping, and assembling complex systems
Some experience with optomechanical system design
Basic coding skills for equipment control
Degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Automation, or Physics
Nice-to-have
A master's degree and 3+ years of relevant experience
Home workshop/lab experience, demonstrated passion for hands-on engineering
Experience building laser machines with comprehensive knowledge of laser system components
System integration expertise across mechanical, electrical, and software domains
Some Circuit design capabilities for custom control systems and instrumentation
