FBAR Filter Designer

About the role

We are seeking an FBAR Filter Designer to lead the development of high-performance RF Front-End (RFFE) solutions. You will own the design lifecycle—from acoustic resonator synthesis to full module integration—bridging the gap between die-level physics and system-level hardware for 5G and Wi-Fi standards.

Responsibilities

• Design & Synthesis: Design high-Q FBAR filters and multiplexers using optimized topologies.
• Layout & Floor Planning: Own the physical die layout and package integration, optimizing for parasitics and thermal dissipation.
• Module Co-Design: Manage the interface between acoustic die, laminate, and PCB to ensure signal integrity and target performance.
• EM Co-Simulation: Lead 3D EM simulations to model package-level parasitics, interconnects, and coupling.
• Yield & Verification: Perform Monte Carlo and corner analyses to ensure robust performance for high-volume manufacturing (HVM).
• Collaboration: Partner with process, modeling, test, module, and other design teams to correlate simulations with measured lab data and drive design iterations.

Requirements

• Acoustic/RF/Microwave Expertise: Deep understanding of FBAR/BAW/SAW physics or extensive experience in RFFE module integration and RF/microwave circuit theory.
• Simulation Mastery: Expert proficiency in ADS and 3D EM tools (e.g., HFSS, CST, or Sonnet).
• System Knowledge: Strong grasp of RFFE architectures, including carrier aggregation and coexistence specifications.
• Communication: Excellent verbal and written skills; ability to explain complex technical trade-offs to cross-functional teams and stakeholders.

Qualifications

• PhD (EE/Physics) with 7+ years experience OR Master’s with 10+ years experience in RF/Microwave design (Acoustic Filter or RFFE Module).
• Proven track record of successful tape-outs or high-volume product releases.

Pay

The annual base salary range for this position is USD 143,800.00 to USD 230,000.00.

Benefits

• Discretionary annual bonus and opportunity to receive new hire equity grant plus annual equity awards.
• Medical, dental, and vision plans.
• 401(K) participation including company matching.
• Employee Stock Purchase Program (ESPP).
• Employee Assistance Program (EAP).
• Company paid holidays, paid sick leave, and vacation time.
• Paid Family Leave and other leaves of absence in accordance with applicable laws.
