What You’ll Do
Design ESA radiating elements: topology selection, bandwidth/dual-pol targets, matching/isolation, and manufacturable stack-up definitions.
Own body-integrated array layout: aperture sizing, element spacing, partitioning/multi-face placement, and mitigation of blockage and platform-induced distortion.
Lead element-to-array EM design closure: converge element, array, and platform coupling performance to meet scan, sidelobe, polarization, and efficiency targets.
Define and execute the calibration strategy: amplitude/phase alignment, channel consistency across temperature, calibration fixture/flow definition, and repeatable performance closure.
Drive optimization loops from measurement feedback: identify dominant error sources (coupling, edge effects, drift, assembly tolerances) and update design and calibration accordingly.
Job Requirements
BS/MS in EE, electromagnetics, RF/microwave, communications, or equivalent practical experience.
5+ years in phased arrays / ESA / antenna arrays, with proven end-to-end ownership from design through measurement and iteration.
Strong fundamentals and hands-on skills in array behavior: scanning, sidelobe control, polarization, efficiency, mutual coupling, edge effects, and error sensitivity.
Practical experience with array calibration and error sources: amplitude/phase errors, temperature drift, phase noise, channel consistency, and compensation methods.
Proficiency with at least one EM tool: HFSS, CST, FEKO (platform-coupled / radome-aware simulations strongly preferred).
Proficiency in MATLAB and/or Python for modeling, beam table generation, test automation, and data analysis.
Hands-on lab/measurement capability: VNA and OTA/anechoic workflows; able to diagnose issues from RF chain to radiation patterns.
Ability to produce clear engineering deliverables: design rules, interface/control specs, test plans, calibration procedures, risk lists, and production recommendations.
Strong cross-functional collaboration skills with RF, mechanical, embedded, and system teams.
Preferred
Ku/Ka satcom terminal experience, or adjacent mmWave array experience (e.g., 28 GHz).
Distributed / conformal / multi-facet arrays integrated onto a body structure, including blockage and platform-induced distortion mitigation.
Packaging and manufacturability experience (AiP/AoB), tolerance sensitivity analysis, and production calibration/DFT planning.
Deep understanding of material and radome impacts (composites, metallic structures, coatings, dielectric variability).
Joint bring-up experience across RF front-end + UDC + timing/sync + compute platform (coherence, spurs, phase-noise budgeting).
