BAW Filter Design Engineer (Starlink/Akoustis)

United States Digital Space LLC; Lockhart (TX); On-site; USD 110,000 - 170,000; Full time

Job summary

Akoustis seeks a BAW Filter Design Engineer to translate concepts into scalable production for Starlink applications. You will design, simulate, and optimize BAW filters while interfacing with process, layout, and test teams to ensure manufacturability and robust performance.

The role requires a bachelor’s in electrical engineering, 1+ year RF/antenna experience, and hands-on EM tool proficiency (HFSS/CST/ADS/COMSOL). Prior exposure to 5G/Wi‑Fi is a plus. On-site presence in Texas is expected.

Qualifications

• Bachelor’s degree in electrical engineering or other engineering discipline.
• 1+ years of experience with RF, antenna, or communication systems (internship and extracurricular experience is applicable).
• 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.

Responsibilities

• 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

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 of enabling human life on Mars.

BAW FILTER DESIGN 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 a superior figure of merit from coupling and Q factor.
