Staff Device Engineer - San Mateo, CA, United States
$120,000 USD yearly
Originally posted 8 July 2026 by the employer.
Develop physics-based models for acoustic resonators using proprietary XBAR technology.
About the role
As a Staff Device Engineer on the Product Integration team, you will lead the development of physics-based models to advance acoustic resonator performance, manufacturability, and reliability. You will work closely with RF designer, technology, and software teams to apply device-level insight toward high-performance RF filters and XBAR technology.
What you'll do
- Lead the development and improvement of physics-based models that enhance acoustic resonator simulation accuracy and support overall RF filter performance. - Direct the analysis of acoustic, electrical, and thermal behaviors to identify performance limits, trade-offs, and mitigation strategies. - Oversee the review and interpretation of large-scale RF data and measurement results to improve modeling fidelity and inform design and technology decisions. - Support experimentation, prototyping, and characterization activities contributing to technology advancement and product development milestones. - Contribute to the continued development of XBAR device knowledge and mentor engineers working on device modeling, characterization, and performance optimization.
What you'll need
- Master’s or PhD in Engineering, Physics, Materials Science, or a related field. - 6+ years of industry experience in device engineering, RF/acoustics, modeling, or semiconductor/MEMS. - Strong expertise in acoustic/RF device modeling (XBAR, SAW, BAW, MEMS). - Proficiency with Python, MATLAB, and FEM tools such as COMSOL or FEMTET. - Demonstrated ownership of major device models, methods, or systems with minimal supervision.
Nice to have
- Hands-on experience with SAW, BAW, XBAR, or MEMS device design or characterization. - Background in semiconductor, MEMS, or acoustic filter fabrication and process integration. - Strong proficiency with FEM/multiphysics tools (e.g., COMSOL, FEMTET). - Experience supporting technology or product development for high-volume commercial applications.
