R&D Device Engineer

R&D Device Engineer At Fab2The 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 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.As an R&D Device Engineer at Fab2, you are the vital link bridging process development, electrical test, and integration. You will define initial transistor architectures and drive deep diagnostic analysis. In this hands-on, high-ownership role, your characterization and parameter extraction will contribute to achieving our targets in device performance, scaling, power, cost and production time.Responsibilities:Design device architectures and tailor novel transistor structures to meet device specificationsExecute tape-outs and test key designsPerform electrical characterization (I-V/C-V) on transistors and MOSCAPs across process splits to establish baseline device behaviorDissect complex electrical and physical data to pinpoint bottlenecks and inform material and flow improvementsExtract core device parameters to construct foundational technology performance modelsRequired experience:MS or Ph.D. in Electrical Engineering, Applied Physics, Solid State Physics, or a closely related fieldRigorous understanding of advanced CMOS/MOSFET device physics and solid-state electronics fundamentalsExperience with semiconductor device measurement (I-V/C-V) and probe station operationStrong skills in data analysis and scripting to accelerate testing and learning cycles.A knack for translating complex device physics concepts clearly to cross-functional partners.Nice-to-have:Familiarity with semiconductor simulation software (e.g., TCAD, HSPICE) and practical experience with Process Design Kits (PDKs) or test chip layoutProficiency in scripting languages (such as Python or MATLAB) to automate testing workflows and large-scale data analysisHands-on experience within a cleanroom environment and a comprehensive understanding of the full CMOS manufacturing process flowBackground in executing semiconductor reliability testing (e.g., HCI, NBTI/PBTI, TDDB) and incorporating degradation mechanisms into process feedbackWe'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: Fab2 offers the following benefits, subject to applicable eligibility requirements:Medical, Dental, and Vision insuranceGenerous Paid Time Off inclusive of Holidays and Sick TimeVisa SponsorshipLife and Disability InsurancePaid Parental Leave401(k) retirement planWeekly Learning & Development opportunitiesCommuter Benefits including Parking and Late Night Uber rides from the officeLunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and SpindriftsWe 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.
