hirify.global develops radar satellite systems and a coordinated constellation for creating high-resolution, real-time 3D maps of Earth.

What you will do

• Develop RF and high-speed measurement solutions for radar payloads and satellite avionics hardware.
• Characterize RF components and subsystems, including LNAs, PAs, mixers, synthesizers, filters, transceivers, and antenna arrays.
• Design test fixtures, harnesses, calibration methods, and de-embedding procedures.
• Develop and execute board- and system-level functional and environmental test plans.
• Debug RF and high-speed subsystems, analyze test data, quantify measurement uncertainty, and recommend improvements.
• Maintain and calibrate RF test equipment and facilities while supporting acceptance, qualification, and flight-readiness decisions.

Requirements

• BS degree in Electrical Engineering, Physics, or a related STEM field, with at least 2 years of related experience.
• Proficiency with RF laboratory equipment, including vector network analyzers, spectrum analyzers, signal generators, power meters, oscilloscopes, and logic analyzers.
• Strong understanding of S-parameters, impedance matching, gain, compression, noise figure, phase noise, intermodulation, and link budgets.
• Experience with calibration, de-embedding, fixture removal, measurement errors, and mitigation strategies.
• Programming or scripting proficiency in Python, C++, or MATLAB, plus the ability to work with Linux terminals and file systems.
• Must meet U.S. ITAR eligibility requirements, including U.S. citizenship, lawful permanent residence, protected individual status, or eligibility to obtain the required U.S. authorizations.

Nice to have
