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 Process Team sits at the heart of our in‑house device development, driving the design of each new generation of tools. This is unlike any role at a traditional foundry—we simultaneously develop recipes, apply novel materials, test and characterize our chips, and troubleshoot tools.

About the role

As a Device Engineer at fab2, you’ll play a critical role in bridging process development, and electrical test. Your work will focus on characterizing semiconductor devices, designing and automating test infrastructure, and extracting key electrical parameters to inform process improvements. This is a hands‑on, high‑ownership role that requires both deep technical understanding and strong collaboration with process, test, and design engineers.

We're looking for someone who’s excited to work across disciplines developing probe cards, designing test structures, running electrical characterization, and building automation infrastructure. A background in device physics and experience with CMOS modeling (e.g., BSIM) will be valuable, especially for parameter extraction and feedback into process development.

You’ll have the opportunity to work across the full testing stack from test structure design to silicon fabrication and data analysis. Your contributions will help shape how we validate and improve our CMOS processes in a fast‑paced, startup environment.

Responsibilities

• Collaborate with process and electrical engineers to design probe cards and test structures
• Design and fabricate CMOS test chips for characterization and calibration
• Develop and implement test plans to extract key device parameters (e.g., threshold voltage, mobility, leakage)
• Deploy parameter extraction tools and methods (e.g., BSIM models) to characterize devices and model performance
• Analyze test data to provide feedback to process engineers, helping improve materials and process flows
• Develop and maintain test automation infrastructure for streamlined electrical characterization
• Document test results and characterization findings clearly and rigorously

Required Experience

• BS, MS, or PhD in Electrical Engineering, Applied Physics, or a related field
• Strong understanding of CMOS device physics and electrical characterization
• Experience with probe station operation
• Familiarity with parameter extraction techniques and device modeling (e.g., BSIM)
• Experience with lab instrumentation and test automation
• Hands‑on experience with semiconductor device fabrication and test structures

Nice‑to‑have

• Experience with process development kits (PDKs) and test chip layout
• Experience with cleanroom fabrication and full CMOS process flow
• Experience conducting reliability testing and analysis

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 $110,000 – $180,000. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in fab2.

Benefits

• Medical, Dental, and Vision insurance
• 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

We are an equal‑opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.

Export Control Analysis: This position involves access to technology that is subject to U.S. export controls. Any job offer made will be contingent upon the applicant’s capacity to serve in compliance with U.S. export controls.
