RF Engineer II (RF and Microwave Hardware Design)

Location: Seattle, Washington; on-site laboratory and hardware-development environment

Company

hirify.global develops intelligent autonomous systems designed to protect service members and civilians.

What you will do

• Design RF and microwave modules from requirements and architecture through schematic capture, layout, bring-up, verification, qualification, and production release.
• Develop active and passive RF circuits, including amplifiers, filters, multiplexers, switches, limiters, couplers, attenuators, detectors, and frequency-conversion stages.
• Design RF front-end assemblies that meet gain, noise figure, output power, linearity, efficiency, stability, isolation, and out-of-band rejection requirements.
• Perform circuit and electromagnetic analysis using ADS, AWR, HFSS, or CST, and correlate simulations with measured hardware performance.
• Create and review RF and mixed-signal PCB designs, then plan and execute laboratory characterization and automated testing.
• Diagnose instability, oscillation, intermodulation, self-interference, desense, thermal drift, mismatch, leakage, and electromagnetic coupling issues while collaborating across engineering, manufacturing, and test teams.

Requirements

• Bachelor’s degree in Electrical Engineering, Applied Physics, or a related field, or equivalent practical experience.
• Typically 1+ years of relevant post-undergraduate experience for L2 or 2+ years for L3; demonstrated technical capability and scope are more important than years alone.
• Hands-on experience designing, building, or debugging RF or microwave circuits, modules, or PCB assemblies through measured verification.
• Knowledge of S-parameters, impedance matching, transmission lines, stability, gain, noise figure, linearity, compression, nonlinear products, isolation, and cascaded RF performance.
• Experience with controlled-impedance RF PCB layouts, grounding, shielding, component placement, laboratory instruments, and calibration methods.
• Ability to work on-site in a laboratory and hardware-development environment.

Nice to have

• RF front-end experience in airborne, defense, space, robotics, or other high-reliability systems.
• Experience with GaN or GaAs power amplifiers, MMICs, LNAs, switches, limiters, frequency converters, or high-selectivity filters.
• Experience with Altium Designer, thermal and RF packaging design, EMI/EMC qualification, and design for manufacturability and test.
• Experience developing characterization or data-analysis tools with Python, MATLAB, or similar tools.
• Ability to obtain an S//SAR security clearance if required by the program.

Culture & Benefits

• Hands-on work in a laboratory and hardware-development environment.
• Cross-functional collaboration with mechanical, thermal, avionics, communications, antenna, manufacturing, and test engineers.
• Participation in environmental and electromagnetic qualification, supplier engagement, ground testing, and flight testing.
• Opportunities to contribute to design reviews, share technical knowledge, and support interns and less-experienced engineers.
