Job Description

Principal Phased Array Antenna Engineer - Radar Payloads

Location

Seattle, WA

Salary: up to $275,000 Gross Per Annum + Stocks/Shares + Brilliant benefits package

You'll join a venture-backed space technology company building the flight-ready electronically scanned antenna arrays at the heart of next-generation spaceborne radar missions.

Our state-of-art antennas need to deliver the gain, efficiency, bandwidth, scan performance, sidelobe control, polarization purity, and calibration accuracy that advanced SAR and target-tracking payloads demand and we're looking for the engineer who can own that problem end to end.

As Principal Antenna Engineer, you'll have ownership of the antenna end to end: requirements and architecture (including interfaces to adjacent systems), EM design, prototype build, measurement, calibration, and qualification.

You'll be the technical owner translating radar performance needs into flight-ready hardware, with a direct line to payload integration and launch.

Day to day, you'll

Own phased-array antenna design and EM modeling, from requirements through architecture and trade studies

Build and measure prototypes, correlating EM models to test data

Optimize and calibrate array performance across frequency and scan angle

Develop beam-steering and alignment methods, working closely with RF, FPGA/DSP, and software teams

Support spacecraft integration and environmental qualification

Mature antenna hardware from prototype to a flight-ready, repeatable product

You'll bring

Expert-level design experience with phased-array / electronically scanned antennas — array theory, impedance and mutual coupling, scan behavior, and polarization

Hands-on experience with beamforming and array calibration

High-frequency PCB, feed, and passive RF component design

Proficiency with EM simulation tools such as HFSS, CST, or FEKO

Programming/scripting skill in Python or MATLAB for modeling and data analysis

Experience with VNA and near-/far-field antenna measurement

Experience carrying RF hardware through space qualification

You'll also need to be hands-on, rigorous, self-driven, and take full ownership of outcomes, with strong first-principles EM judgment, discipline about correlating models to test data, and comfort operating with ambiguity and evolving requirements; while collaborating closely across RF, digital, mechanical, thermal, and software disciplines.

This role may require access to U.S. export-controlled information and may require the ability to obtain a U.S. government security clearance. Candidates must be a U.S. citizen to be eligible.
