Reflector/Feed Antenna Engineer - TeraWave

Application close date: 07/7/2026 Location: United States, Washington, Seattle Responsibilities Reflector Architecture – Lead design and trade studies for high‑gain reflector systems (Cassegrain, Gregorian, Offset‑fed) meeting strict gain, beamwidth, and sidelobe requirements at E‑band. Feed System Development – Own the mmWave feed chain, including corrugated horns, OMTs, and diplexers supporting dual‑circular polarization for 71‑76 GHz (downlink) and 81‑86 GHz (uplink). EM Simulation – Model large‑aperture performance using PO/GTD tools (GRASP/TICRA) and full‑wave solvers (HFSS/CST), optimizing spillover, illumination, and aperture efficiency. Tolerance & Sensitivity – Perform mechanical and thermal sensitivity analyses on surface RMS error, feed alignment, vertex offsets, and structural deformation. Cross‑Functional Integration – Work with Mechanical and Thermal teams to select low‑CTE materials and manufacturing processes that preserve RF performance in space environments. Test & Verification – Define test plans and lead anechoic‑chamber characterization of flight hardware, focusing on axial ratio, isolation, and high‑frequency gain patterns. Vendor & Build Management – Interface with specialized E‑band fabrication vendors, ensuring manufacturability and guiding hardware from EM concept to flight‑ready configuration. Basic Qualifications Education – B.S. in Electrical Engineering with 5+ years RF antenna experience, or M.S./Ph.D. with 3+ years. Electromagnetics – Deep understanding of EM theory applied to reflector geometries and aperture efficiency optimization. Design Leadership – Demonstrated ownership of a reflector or complex feed‑system program from concept through hardware delivery. Simulation Tools – Proficiency with PO/GTD tools (TICRA/GRASP) and 3D full‑wave solvers (HFSS, CST). Feed Chain Expertise – Experience designing dual‑CP feed systems with strong axial‑ratio and isolation performance. mmWave Testing – Familiarity with 70+ GHz measurement techniques, including far‑field/near‑field testing and waveguide‑band VNA calibration. Preferred Qualifications Advanced Degree – Ph.D. in EE with focus on mmWave EM, antennas, or quasi‑optics. EBand Flight Heritage – Experience designing hardware for 71‑76 / 81‑86 GHz space systems, including thermal‑stability considerations. Component‑Level Specialization – Expertise with OMTs, septum polarizers, corrugated horns, and high‑rejection diplexers. Tolerance & POGO Analysis – Demonstrated ability to analyze reflector surface RMS and feed alignment sensitivities. Advanced Manufacturing – Experience with CNC micromilling, diffusion bonding, or additive manufacturing for E‑band components. Material Science – Knowledge of low‑CTE materials (Invar, graphite‑cyanate ester) and their RF behavior across extreme thermal gradients.
