Job description

the company was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today the company is actively developing the technologies to make this possible, with the ultimate goal ofenabling human life on Mars.

BAW DEVICE ENGINEER (STARLINK/AKOUSTIS)

Akoustis is now operating as a wholly owned subsidiary of the company, providing industry leading RF filters using patented XBAW technology to help drive the mission of making human life multi-planetary and connecting the world through Starlink.We design, build, launch, and operate the world's largest constellation of satellites, enabling us to operate a global internet network unbounded by traditional ground infrastructure limitations. The root of the company’s success so far lies in our mission to keep all engineering and production in-house, which enables a tight feedback loop, nimble decision-making, and speedy deliverables. With millions of daily users worldwide already online, Starlink is truly a game-changer and levels the playing field for those who were previously unconnected.

XBAW technology utilizes MEMS-based thin film transfer process, enabling a broad range of piezoelectric material synthesis and compositions tailored for specific application needs with enhanced material properties and an optimized resonator performance including superior figure of merit from coupling and Q factor. Our Device Engineers plays a critical role in developing and improving XBAW resonators and supporting filter designs. This person will perform FEM simulations and experimental DOE to improve the figure of merit of BAW resonators, with an emphasis on developing efficient process integration and reduced cycle time for lean filter development.
