Entry Level Thermal Engineer Jobs in Austin, TX (NOW HIRING)

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.

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.

We are seeking a highly skilled and hands-on Mechanical Engineer to join our team. You will be responsible for designing, prototyping, and building the mechanical systems in our semiconductor fabrication equipment, from stages and frames up to complete systems.

This role is for someone who has internalized precision machine design as a discipline and has a proven track record of rapidly prototyping complex precision 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!

• Design and iterate on precision machines, motion stages, structural loops, metrology frames, opto-mechanical mounts, test fixtures, and inspection tooling targeting sub-micron to nanometer performance
• Lead mechanical system integration, alignment procedures, and cross-team coordination with electrical, controls, and optics engineers
• Drive mechanical design of frames, stages, and assemblies with GD&T, tolerance analysis, and a practical eye toward manufacturability and assembly
• Rapidly prototype, build and characterize new designs on the bench using a variety of tools and characterization equipment
• Select and integrate precision components: bearings, encoders, interferometers, actuators, isolators, and dampers
• Develop error budgets and tolerance stack-ups; identify and mitigate dominant error sources (thermal, vibrational, structural, kinematic)

• 3 years designing and building precision mechanical systems that had to hit real accuracy and repeatability targets
• Working fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysis
• Hands-on prototyping, fabrication, assembly, and alignment experience — you're comfortable on a mill, on a granite surface plate, and behind an interferometer
• Experience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators)
• Experience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMs

• Formal training in precision engineering
• Experience at an early-stage startup
• Familiarity with firmware, controls, or electrical engineering
• Opto-mechanical design and alignment experience

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

fab2 is committed to fair and equitable compensation practices. We're hiring this role from mid-level through staff. The annual salary range for this role is $105,000 - $200,000. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in fab2.

• Generous Paid Time Off inclusive of Holidays and Sick Time
• Visa Sponsorship
• Life and Disability Insurance
• Paid Parental Leave
• 401(k) retirement plan
• Weekly Learning & Development opportunities
• Commuter Benefits including Parking and Late Night Uber rides from the office
• Lunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts
