• Design and bring-up of RF boards (filters, LNAs, mixers, switches, power amps, etc.)

• Test setup automation using Python (SCPI, PyVISA) for metrics like EVM, P1dB, SNR, ACLR

• Hardware testing with VNAs, signal generators, spectrum analyzers, and SDRs

• Antenna trade studies and performance validation

• EMI/EMC compliance reviews, shielding, grounding strategies

• Support for PDR, CDR, and pre-launch test campaigns

Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering or related field

• 2–5 years of experience in RF hardware development or satellite comms systems

• Familiarity with RF performance metrics (EIRP, G/T, noise figure, group delay, IP3, etc.)

• Hands-on experience with lab test equipment (VNA, spectrum analyzer, signal gen, etc.)

• Proficiency with tools such as Altium, MATLAB, Python, PyVISA

• Experience building and testing SDR-based systems

• Working knowledge of antenna types and RF path loss in space environments

• Ability to work in-person or willingness to relocate to Palo Alto, CA

• Willingness to travel for work
