Staff R&D Device Engineer

About the role

As an Staff 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 specifications
• Execute tape-outs and test key designs
• Perform electrical characterization (I-V/C-V) on transistors and MOSCAPs across process splits to establish baseline device behavior
• Dissect complex electrical and physical data to pinpoint bottlenecks and inform material and flow improvements
• Extract core device parameters to construct foundational technology performance models

Required experience

• Ph.D. in Electrical Engineering, Applied Physics, Solid State Physics, or a closely related field
• Rigorous understanding of advanced CMOS/MOSFET device physics and solid-state electronics fundamentals
• Deep experience with semiconductor device measurement (I-V/C-V) and probe station operation
• Strong 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 layout
• Proficiency in scripting languages (such as Python or MATLAB) to automate testing workflows and large-scale data analysis
• Hands-on experience within a cleanroom environment and a comprehensive understanding of the full CMOS manufacturing process flow
• Background in executing semiconductor reliability testing (e.g., HCI, NBTI/PBTI, TDDB) and incorporating degradation mechanisms into process feedback

• Working at fab2
• We’re an early-stage hardware startup with solid funding, world-class advisors, and labs/offices in Austin, TX, Lockhart, TX, and San Francisco, CA.
