Senior Test Development Engineer

About Atomic Machines

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler™ technology. This full-stack technology enables new classes of micromachines to be designed and built by offering manufacturing processes and a materials library that is inaccessible to semiconductor manufacturing methods. It promises to unlock MEMS manufacturing for the many device classes frustrated by semiconductor methods and to open up entirely new product classes. The Matter Compiler™ technology fully realizes the digital manufacturing dream: bits and raw materials go in, and complete, functional micromachines come out.  The Atomic Machines team has also created an exciting first device – one that was only made possible by the existence of the Matter CompilerTM technology – that we will be unveiling to the world soon.

Our offices are in Emeryville and Santa Clara, California.

About The Role:

We are seeking a Senior Test Development Engineer with a strong electrical engineering background to join our growing Test team. At Atomic Machines, we are building a novel robotic manufacturing platform—the Matter Compiler™—from the ground up. This enables us to explore entirely new materials and processes, making possible a class of devices that cannot be fabricated in conventional fab environments. From a test perspective, this means we design novel tests, frequently build our own hardware, and ultimately integrate those tests into a fully automated production framework.

As part of the test group, you will work on complex multidisciplinary problems. You will have the opportunity to define novel tests from initial specifications through initial design, design and build custom hardware, and integrate it into a complete system. Your test development can include mechanical fixturing, circuit board design, firmware development, integration of existing equipment, and analysis of resulting data. You will work closely with colleagues from Device Design, Go-To-Market, and Production to specify, implement, and validate tests.

In addition to a strong electrical engineering background, the ideal candidate will bring strong first principles thinking, creativity, and a generalist mindset. There are typically multiple approaches to developing any test, and navigating design/fabrication/results tradeoffs is where someone with a first principles approach will excel.

What You'll Do

• Develop novel test instrumentation from initial specification through validation
• Collaborate with cross-functional teams in device design, product development, and manufacturing to develop new classes of tests driven by customer and product requirements
• Integrate off-the-shelf instrumentation with existing and custom tests
• Design and build circuit boards for test instrumentation
• Design and implement novel test functionalities
• Document test instrumentation design and operating procedures
• Transfer tests from development to production
• Maintain test development facilities

What You'll Need

• 5+ years of experience in circuit design, instrumentation development, or test engineering.
• Demonstrated experience in full board development from initial circuit concepts through PCB layout, including defining specifications, validating functionality at the schematic level, and executing PCB layout
• Designing with Altium 365
• Deep understanding of analog and mixed-signal circuit design
• Experience implementing analog system control using microcontrollers
• Familiarity with hardware-level communication protocols
• Ability to develop microcontroller code in C
• Strong documentation skills for clear hardware handoff to system-integration teams
• Proficiency with standard electronic test equipment
• Experience developing instrumentation, including constructing and managing error budgets
• Solid hands-on lab skills, including soldering, hardware build/test, and iterative refinement
• A first-principles mindset — you question assumptions, reframe problems from the ground up, and approach challenges with a foundational understanding rather than relying solely on precedent.
• Bachelor's degree in Electrical Engineering or Physics. A PhD in a hard science or engineering discipline is strongly preferred.

Bonus Points For

• High current (500A+) or high voltage (1kV+) systems experience
• Experience developing with the STM32 microcontroller platform
• Experience with reliability or environmental test systems
