About the Job

Requirements

A bachelor's degree in electrical engineering or another engineering discipline is required.
At least 5 years of experience in radio-frequency filter design, focused on bulk acoustic wave or surface acoustic wave filters, is required.
Experience with electromagnetic simulation tools such as HFSS, CST, ADS, or COMSOL is required.
Experience with radio test and measurement equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, and network analyzers is required.
Must be willing to work extended hours and weekends as needed to meet critical milestones.

Responsibilities

Design and develop bulk acoustic wave filters from concept to production, including specification definition, simulation, characterization, front-end and back-end testing, architecture design, and performance optimization.
Perform advanced electromagnetic simulations using tools such as HFSS, ADS, or COMSOL to model bulk acoustic wave filter performance, optimize designs, and ensure manufacturability.
Design radio-frequency modules integrating bulk acoustic wave filters, including layout, packaging, and integration with other radio-frequency components such as amplifiers, switches, and antennas.
Optimize filter performance for insertion loss, return loss, bandwidth, and out-of-band rejection while meeting size and cost constraints.
Work with process engineers, layout designers, and system architects to integrate bulk acoustic wave filters into larger radio-frequency systems.
Develop test plans, perform radio-frequency measurements, and validate filter performance using tools such as network analyzers and spectrum analyzers.
Create detailed design reports, simulation results, and technical documentation to support design reviews and production handoff.
Stay informed about industry trends and advances in bulk acoustic wave technology and contribute to next-generation radio-frequency solutions.

Desired Qualifications

A master's degree or PhD in electrical engineering with an emphasis in radio-frequency or antenna engineering is preferred.
Experience with fifth-generation wireless, Wi-Fi, or Internet of Things radio-frequency front-end module design is preferred.
Familiarity with microelectromechanical systems fabrication processes for bulk acoustic wave filters is preferred.
Knowledge of mixed-signal design and co-simulation with analog and digital circuits is preferred.
Experience with scripting languages such as Python or MATLAB to automate simulation and testing workflows is preferred.

SpaceX 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 SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

SR. BAW FILTER DESIGN ENGINEER (STARLINK/AKOUSTIS)

Akoustis is now operating as a wholly owned subsidiary of SpaceX, 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 SpaceX’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 a superior figure of merit from coupling and Q factor.

About the Company

SpaceX

Builds rockets and runs Starlink satellite internet

SpaceX builds and launches reusable rockets and spacecraft for NASA, the military, and companies, and it runs Starlink, a satellite internet service for homes and businesses. In 2020, its Dragon capsule became the first privately built spacecraft to carry astronauts to the International Space Station. Its Falcon 9 rocket lands its first stage so the booster can fly again, which cuts launch costs, while Starlink beams internet from low-orbit satellites to small dishes for a monthly fee. SpaceX also owns xAI, maker of the Grok chatbot and owner of the social network X, and is building Starship, a fully reusable rocket meant to carry people to the Moon and Mars. Elon Musk founded SpaceX in 2002, and it is based in Starbase, Texas.
