We are seeking an RF and Microwave Hardware Design Engineer to design and deliver compact, high-performance RF modules for airborne and ground systems. You will own active and passive RF circuits, PCB assemblies, packaging interfaces, laboratory verification, and transition to production. The center of gravity of this position is hands-on module design rather than top-level communications architecture, waveform development, or link-budget ownership. 


WHAT YOU’LL DO:

  • Own RF and microwave module designs from requirements and architecture through schematic capture, component selection, layout, bring-up, verification, qualification, and production release. 
  • Design active and passive RF circuits such as low-noise amplifiers, power amplifiers, filters and multiplexers, RF switches, limiters, couplers, attenuators, power detectors, and frequency-conversion stages. 
  • Develop RF front-end assemblies that meet gain, noise figure, output power, linearity, compression, efficiency, harmonic and spurious-emission, stability, isolation, and out-of-band rejection requirements. 
  • Perform circuit and electromagnetic analysis using tools such as Keysight ADS, Cadence AWR, HFSS, or CST, and correlate models with measured hardware performance. 
  • Create and review RF and mixed-signal PCB designs, including controlled-impedance routing, grounding, shielding, stack-up definition, power distribution, and placement of sensitive or high-power components. 
  • Plan and execute laboratory characterization using network analyzers, spectrum analyzers, signal generators, noise-figure analyzers, power meters, oscilloscopes, and automated test equipment. 
  • Diagnose difficult hardware issues involving instability, oscillation, intermodulation, self-interference, desense, thermal drift, mismatch, leakage, and electromagnetic coupling. 
  • Work closely with mechanical, thermal, avionics, communications, antenna, manufacturing, and test engineers to integrate RF hardware into size-, weight-, power-, cooling-, and environmental constraints. 
  • Develop verification methods, production test strategies, calibration approaches, and clear technical documentation that make designs repeatable and manufacturable. 
  • Support environmental and electromagnetic qualification, supplier engagements, hardware integration, ground test, and flight test as needed. 
  • Contribute to design reviews, share technical knowledge, and mentor other engineers at a level appropriate to the position. 
  • Perform other duties as assigned. 
  •  
     
     
     
     
     
     
     
     
     
     

REQUIRED QUALIFICATIONS:

  • Bachelor's degree in Electrical Engineering, Applied Physics, or a related field, or equivalent practical experience. 
  • Hands-on experience owning an RF or microwave circuit, module, or PCB assembly through fabrication, bring-up, debugging, and measured verification. 
  • Strong understanding of S-parameters, impedance matching, transmission lines, stability, gain and noise figure, linearity and compression, nonlinear products, isolation, and cascaded RF performance. 
  • Experience creating or reviewing RF PCB layouts with controlled impedance, grounding, shielding, component placement, and signal-integrity considerations. 
  • Proficiency with common RF laboratory instruments and calibration methods, with the ability to distinguish hardware behavior from measurement artifacts. 
  • Ability to use simulation and measured data to make sound design decisions, document tradeoffs, and close requirements with objective evidence. 
  • Clear written and verbal communication skills and the ability to work effectively with cross-functional engineering and manufacturing teams. 
  • Ability to work on-site in a laboratory and hardware-development environment. 
  •  
     
     
     
     
     
     

PREFERRED QUALIFICATIONS:

  • Experience with RF front ends for airborne, defense, space, robotics, or other high-reliability systems. 
  • Experience integrating GaN or GaAs power amplifiers, MMICs, LNAs, switches, limiters, frequency converters, or high-selectivity filter technologies. 
  • Experience designing for simultaneous transmit and receive operation, high-power RF, intermodulation control, adjacent-band rejection, or co-site interference and desense. 
  • Experience with Altium Designer and one or more RF or electromagnetic simulation environments such as ADS, AWR, HFSS, or CST. 
  • Working knowledge of thermal design, RF packaging, connector and cable interfaces, tolerance analysis, and design for manufacturability and test. 
  • Experience with EMI and EMC design and qualification for military or aerospace hardware. 
  • Experience developing automated characterization or data-analysis tools in Python, MATLAB, or a similar environment. 
  • Experience transitioning RF hardware from prototype through qualification and low-rate production. 
  • Ability to obtain a U.S. security clearance, including access at the S/SAR level, if required by the program. 
  •

What We Do

At Shield AI, you won't wait years to see your work reach the field. You'll build hardware and software that operates in the real world right now, in the hands of the people who depend on it. Hivemind, our AI pilot, has been flying since 2018. It has flown more than 30 platforms, including an F-16, and it now sits under a U.S. Air Force production contract for Collaborative Combat Aircraft. When you write code or shape a system here, you contribute to technology with a proven flight record and a clear production future. V-BAT flies intelligence, surveillance, and reconnaissance missions with an operational record that stretches from Ukraine to the Indo-Pacific. It delivers eyes where they matter most, in the most demanding conditions on earth. The teams behind it watch their work get tested where the stakes are real. X-BAT takes its first flight this year. It's an AI-piloted fighter that needs no runway, built to operate where traditional aircraft can't. Join now and you help shape a program at its earliest, most formative stage. That's the kind of ground-floor work that defines a career. Do the most impactful work of your life, on problems that matter. Autonomy at this level asks a lot of you. You'll take on problems in perception, planning, and control that few teams anywhere are equipped to solve. You'll work across disciplines, from aerospace and robotics to machine learning and systems engineering, alongside people who hold themselves to an exacting standard and expect the same from you. Our mission is clear: protect service members and civilians with intelligent systems. That purpose runs through every decision, every design review, and every deployment. It's why the work here carries a weight you can feel. Ready to join our mission? Explore our open roles and find where you fit.

Why Work With Us

Founded in 2015 by a former Navy SEAL, Shield AI builds AI pilots and uncrewed aircraft. Veterans aren't an afterthought here, they're at every level. It's why the work carries weight: AI pilots and uncrewed aircraft flying real missions, from Ukraine to the Indo-Pacific, protecting service members and civilians.
