Job description

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 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 Precision Team operates on the nanometer scale. We make lithography, metrology and motion systems that pattern, inspect and characterize our chips in order to push our process to lower nodes.

About the role
We are seeking a highly skilled and hands‑on Optomechanical Engineer to join our team. This role is for someone who has internalized precision machine design as a discipline and has a proven track record of rapidly prototyping complex optical systems and advancing them to the next stage of production. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve actually built!
The core responsibility of the job is the design, assembly, testing, and debugging of new electromechanical and optical systems. You’ll be responsible for building new systems as well as integrating off‑the‑shelf products, such as motion stages and metrology equipment.

Responsibilities

• Design, prototype, and develop precision electro‑mechanical/optical components and systems

• Build new systems and integrate off‑the‑shelf products, such as motion stages and metrology equipment.

• Perform detailed analysis and simulations to evaluate system designs and meet constraints

• Work with suppliers to source components and materials

Required Experience

• Bachelor's degree or higher in Mechanical Engineering.

• 6+ years of industry experience in electromechanical or optics system design and analysis

• Working fluency in precision machine design fundamentals: exact‑constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysis

• Mechanical 3D CAD experience

• Experience designing and simulating optical systems (Zemax preferred)

Nice‑to‑have

• Formal training in precision engineering

• Experience at an early‑stage startup

• Familiarity with firmware, controls, or electrical engineering

Working at fab2

We’re an early‑stage hardware startup with solid funding, world‑class advisors, and offices in Austin, TX and San Francisco, CA.

Compensation: fab2 is committed to fair and equitable compensation practices. The annual salary range for this role is $130,000 – $200,000. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in fab2.
