Job summary

Assured Space Access Technologies, Inc. in Irvine, CA is seeking a Microwave Engineer to design the passive and active microwave hardware for phased array and radar systems.

You will take structures from EM models through fabrication, focusing on loss, isolation, power handling, and manufacturability in a repair/overhaul environment. The role requires 7+ years of hands-on microwave design experience, strong S-parameters knowledge, and proficiency with HFSS/CST and ADS/AWR tools.

Qualifications

• Bachelor’s degree in electrical engineering or physics with emphasis on applied electromagnetics and microwave engineering.
• 7+ years of hands-on microwave component and assembly design experience through at least 20 GHz, with exposure to 40 GHz designs.
• Strong command of transmission line theory, S-parameters, impedance matching, filter synthesis, and network analysis.
• Proficiency with 3D electromagnetic solvers such as HFSS or CST Microwave Studio, and with circuit simulators such as Keysight ADS or Cadence AWR Microwave Office.
• Hands-on vector network analyzer measurement skills, including multi-port calibration, de-embedding, and fixture design.
• Ability to obtain and maintain a U.S. Secret clearance; U.S. citizenship required.
• On-site work in Irvine, CA.

Responsibilities

• Design, simulate, and validate passive microwave structures including filters, diplexers, directional couplers, power dividers and combiners, transitions, and waveguide assemblies operating from 0.5 to 40 GHz.
• Design microwave transmission line structures, such as microstrip, stripline, grounded coplanar waveguide, and substrate-integrated waveguide, including impedance control, mode suppression, and loss budgeting on low-loss laminates.
• Perform 3D electromagnetic analysis using HFSS, CST Microwave Studio, or equivalent tools, and correlate simulated performance with measured S-parameters, identifying and resolving discrepancies.
• Develop high-power microwave designs with attention to peak and average power handling, thermal dissipation paths, breakdown and corona margin, and passive intermodulation performance.
• Design and integrate MMIC-based and hybrid microwave assemblies, including chip-and-wire layouts, bond-wire compensation, hermetic packaging, and cavity-resonance mitigation.
• Establish measurement approaches and test fixturing, including multi-port calibration, de-embedding, time-domain gating, and correlation between fixtured and in-situ results.
• Support fault isolation, rework, and requalification of microwave assemblies returned for repair and overhaul, and define repeatable, documented repair processes.
• Collaborate with antenna, RF, mechanical, and manufacturing engineers to close mechanical, thermal, and interface requirements early in the design cycle.
• Mentor junior engineers on microwave design fundamentals, measurement discipline, and troubleshooting methodology.
• Support technical reviews, risk assessments, and project documentation.
• Travel as needed to facilities, test ranges, or vendor sites for evaluations and integrations.
