Senior Mechanical Integration & Test Engineer

Role Summary

About fab2

The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves.

We're looking for exceptional, hands-on people who can iterate to the limits of what's possible.

fab2 was founded by Sam Zeloof https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). 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.

We are looking for a Test Engineer to be the critical interface between every team at fab2. You will get to work across every tool we are building, applying a deeply scientific mindset to characterize tools, intuit potential problems, and diagnose complex failures.

This is a dedicated test and applications role. You'll know you've succeeded when you build and execute test plans that improve the design of our tools in your first month. By month 3, you will be autonomously solving highly complex problems for our positioning tools, and by month 6, your impact will scale across multiple teams and systems. Our philosophy is to get things built/tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve built!

Responsibilities

• Own the end-to-end characterization of tools, defining criteria to measure, running software tests, pushing the limits of our hardware, and logging failure to inform engineering decisions
• Build software testing programs from scratch
• Diagnose complex system errors by sitting down with electrical, mechanical, and software teams to map out problem matrices and track down root causes
• Lead with rigorous and concise written and verbal communication
• Set clear timelines and hold yourself and cross-functional teams accountable for rigorous documentation and testing standards

Requirements

• 2 years of experience as a test engineer or applications engineer with a demonstrated command of best practices in finding and diagnosing errors
• Ability to write code and create automated testing programs from scratch
• Hands-on capability to build and run electrical tests
• Strong mechanical intuition combined with a highly detail-oriented, scientific mindset
• Clear, fast verbal and written communication skills to effectively interface across multiple engineering disciplines

Nice-to-have

• Prior experience with mechanical design
• PCB design experience

About the Company

The Tool Software team builds the software that runs fab2's semiconductor fabrication tools. We work across the stack, from microcontroller firmware and real-time control to Linux applications for calibration, diagnostics, simulation, build/release infrastructure, and over-the-air deployment.

Our software sits close to the hardware and directly affects tool performance, uptime, process repeatability, and fab throughput. We partner closely with electrical, mechanical, process, and fab teams to bring new equipment online and scale it into production.
