Sr. BAW Device Engineer (Starlink/Akoustis)

SpaceX is actively developing technologies to enable human life on Mars and connect the world through Starlink, the world's largest constellation of satellites. Akoustis, a wholly owned subsidiary of SpaceX, provides industry-leading RF filters using patented XBAW technology to support this mission. XBAW technology leverages a MEMS-based thin film transfer process, enabling tailored piezoelectric material synthesis for optimized resonator performance, including superior figure of merit from coupling and Q factor.

About the role

As a Senior BAW Device Engineer, you will play a critical role in developing and improving XBAW resonators and supporting filter designs. You will perform FEM simulations and experimental DOE to enhance the figure of merit of BAW resonators, with a focus on efficient process integration and reduced cycle time for lean filter development.

Responsibilities

• Develop and improve FEA setups (COMSOL, HFSS) for BAW resonator simulations and optimization
• Improve the performance of bulk acoustic wave resonators for RF filter applications
• Develop and enhance thin film bulk acoustic wave resonator processes for better performance, accuracy, high yield, and short cycle time
• Support BAW filter design with dimensions and process integration
• Define and generate resonator equivalent circuit models for use in filter design
• Plan experimental setups with multiple parameters
• Perform scientific and statistical analysis of RF test results of BAW resonators
• Support problem-solving in filter design, reliability, and yield improvement

Qualifications

Basic Qualifications

• Bachelor’s degree in an engineering discipline
• 5+ years of experience with semiconductor devices, RF, antenna, or communication systems (internship and extracurricular experience is applicable)

Preferred Qualifications

• Advanced degree in an engineering or STEM discipline
• 10+ years of experience in BAW/MEMS technology
• 10+ years of semiconductor device experience
• Strong background in RF BAW resonator physics and technology development
• Strong background in RF circuits and electromagnetics
• Understanding of statistical analysis of characterization and modeling data for evaluation of DOE
• Understanding of equivalent device circuit models to support IC designs

Additional Requirements

• Must be willing to work extended hours and weekends as needed to meet critical milestones
