BAW Filter Design Engineer

About the role

Akoustis, a subsidiary of SpaceX, is seeking a dedicated BAW Filter Design Engineer to join the Starlink team and contribute to the expansion of global connectivity. In this role, you will own the full design lifecycle of bulk acoustic wave filters, ensuring they meet the stringent performance and reliability standards required for satellite communication systems. You will be responsible for translating complex system requirements into robust filter designs that enable seamless RF performance in a demanding space environment. The position requires close collaboration with cross-functional teams to align filter development with the broader objectives of the Starlink network and Akoustis technology roadmap. You will leverage advanced simulation and measurement techniques to solve challenging electromagnetic and mechanical packaging problems. Success in this role depends on your ability to manage multiple design iterations while maintaining clear documentation and communication. You will play a critical role in advancing the manufacturability and performance of RF front-end components that directly impact the quality of service for end users.
