We partner with leading universities and national labs to solve deep technical challenges in wireless communication, data movement, and infrastructure design.
If you're excited by elegant systems, complex architecture, and creating the blueprint for something truly groundbreaking, this is your moment.
About the Role
As Senior/Lead RF Engineer, you'll design and validate next-generation mmWave RF front-ends and antenna systems. Working directly with our Wireless Tech Lead, you’ll take a hands-on role in RF hardware development—from simulation and circuit design to lab testing and production integration.
This role offers deep technical ownership in a small, elite team, with the opportunity to influence the RF roadmap for some of the world’s most advanced wireless systems.
What You’ll Do
Lead RF hardware design from concept through prototyping and production
Simulate and implement mmWave RF circuits, front-ends, and antenna systems
Build and validate custom RF modules for ultra-high-speed wireless links
Perform link budget analysis and optimize for performance and reliability
Establish RF testing protocols and validation workflows
Collaborate with digital/FPGA, embedded, and mechanical engineering teams
Drive RF hardware roadmap and lead field trials, demos, and production testing
Interface with component suppliers, manufacturing partners, and test labs
What We’re Looking For
6+ years of hands-on experience in RF or mmWave engineering
Proficiency with EM simulation tools (CST Studio, HFSS, ADS)
Deep understanding of impedance matching, RF front-end design, and power amplifiers
Expertise with lab measurements: VNA, spectrum analyzers, anechoic chamber setups
Experience bringing RF hardware from prototype to production
Background in antenna design or high-frequency PCB layout
Strong communication skills and the ability to mentor junior engineers
Familiarity with manufacturing processes and cost optimization
