Sr. BAW Filter Design Engineer; Starlink​/Akoustis

Bastrop, TX

Space

X 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 Space

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

Akoustis is now operating as a wholly owned subsidiary of Space

X, 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.

• Responsible for designing and developing BAW filters from concept to production, including specification definition, simulation, characterization, front‑end and back‑end testing, architecture design, and performance optimization.
• Perform advanced EM simulations using tools such as HFSS, ADS, or COMSOL to model BAW filter performance, optimize designs, and ensure manufacturability.
• Design RF modules integrating BAW filters, including layout, packaging, and integration with other RF components such as amplifiers, switches, and antennas.
• Optimize filter performance for key metrics such as insertion loss, return loss, bandwidth, and out‑of‑band rejection, while meeting size and cost constraints.
• Work closely with process engineers, layout designers, and system architects to ensure seamless integration of BAW filters into larger RF systems.
• Develop test plans, perform RF measurements, and validate filter performance using tools like network analyzers and spectrum analyzers.
• Create detailed design reports, simulation results, and technical documentation to support design reviews and production handoff.
• Stay updated on industry trends and advancements in BAW technology, contributing to the development of next‑generation RF solutions.

• Bachelor’s degree in electrical engineering or other engineering discipline.
• 5+ years of experience in RF filter design with a focus on BAW or SAW.
• Experience in EM simulation tools (e.g. HFSS, CST, ADS, or COMSOL).
• Experience with radio test and measurement equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, and network analyzers.

• Master’s degree or PhD in electrical engineering with emphasis in RF/antenna engineering.
• Experience with 5G, Wi‑Fi, or IoT RF front‑end module design.
• Familiarity with MEMS fabrication processes for BAW filters.
• Knowledge of mixed‑signal design and co‑simulation with analog/digital circuits.
• Experience with scripting languages (e.g., Python, MATLAB) for automation of simulation and testing workflows.

• Must be willing to work extended hours and weekends as needed to meet critical milestones.
• To conform to U.S. Government export regulations, applicant must be a U.S. citizen, lawful permanent resident, refugee, asylee, or otherwise eligible to obtain required authorizations from the U.S. Department of State.
