Principal RF & Microwave Engineer

Principal RF & Microwave Engineer – Directed Energy / Counter-UAS
Company: Hexon Technology
Location: 100% Remote
Type: Full-Time or Founding/Consulting-to-Full-Time

About Hexon
Hexon Technology is building ATLAS, an edge-based defense platform designed to combine sensors, persistent tracking, intelligent decision support, and multiple effectors into a unified system for protecting critical infrastructure and sensitive environments.
Our objective is to build a platform capable of detecting, understanding, prioritizing, and responding to emerging threats, including unmanned aerial systems.
We are expanding ATLAS into counter-UAS and directed-energy applications and are looking for a senior RF technical leader to help establish this capability from the ground up.
The Role
We are seeking a Principal RF & Microwave Engineer who can serve as the technical lead for our RF and directed-energy development efforts.
This is not a narrow design role.
You will help define the RF architecture, evaluate technical approaches, establish laboratory and test capabilities, develop prototypes, recruit additional specialists, and integrate RF hardware with the ATLAS command-and-control platform.
The ideal candidate combines the architectural experience of a chief engineer with the ability to remain deeply hands-on.
Relevant backgrounds include:
High-power RF and microwave systems
Directed-energy research and development
Electronic warfare
Radar systems
Active electronically scanned arrays and phased arrays
RF power electronics
Counter-UAS systems
Defense RF systems
What You’ll Do
Serve as the technical authority for Hexon’s RF and microwave engineering efforts
Develop system-level RF architecture for future ATLAS-integrated counter-UAS capabilities
Lead RF/microwave modeling, simulation, prototyping, characterization, and testing
Evaluate RF sources, amplifiers, antennas, arrays, power architectures, and supporting technologies
Develop requirements and interfaces between RF hardware and ATLAS
Work with antenna, embedded, FPGA, power, thermal, mechanical, controls, and software engineers
Establish safe laboratory development and test processes
Lead electromagnetic compatibility and interference considerations across the platform
Help define verification, validation, instrumentation, and test requirements
Evaluate commercial components and potential technology partners
Translate operational counter-UAS requirements into engineering requirements
Help recruit and mentor a larger RF/direct-energy engineering organization as the company grows
Work directly with Hexon’s founder and ATLAS engineering team on technical strategy and product development
What We’re Looking For
Required
10+ years of professional RF, microwave, radar, EW, directed-energy, or closely related engineering experience
B.S. or higher in Electrical Engineering, RF Engineering, Applied Physics, or a related discipline
Deep understanding of RF/microwave systems and electromagnetic principles
Experience taking sophisticated RF hardware from concept through prototype and testing
Experience with RF simulation, measurement, instrumentation, and laboratory development
Strong understanding of antennas, RF propagation, amplifiers, signal chains, and RF system architecture
Ability to work across hardware and software boundaries
Experience leading multidisciplinary engineering efforts
Ability to operate in an early-stage environment where you will both design the architecture and work directly on the hardware
Highly Desired
Experience in one or more of the following:
High-power microwave systems
Directed-energy systems
Counter-UAS
Electronic warfare
Radar
Phased arrays / AESA
Beamforming
High-power RF amplifiers
GaN RF systems
Pulsed-power systems
FPGA-controlled RF systems
Defense system integration
EMI/EMC engineering
What Makes This Different
We are not looking for someone to maintain an existing RF product.
You will have the opportunity to help define an entirely new capability within ATLAS.
The long-term objective is an architecture where ATLAS can integrate sensing, tracking, identification, decision support, and multiple counter-UAS effectors through a common command-and-control platform.
You would be one of the technical leaders responsible for turning that vision into real hardware.
Ideal Candidate
You have spent years building serious RF systems and have reached the point where you want more ownership.
You can sit at a whiteboard and architect a system in the morning, work with engineers in the lab that afternoon, brief leadership on technical risk the next day, and eventually build the engineering organization required to take the technology into the field.
If you’ve worked on advanced RF, radar, electronic warfare, counter-UAS, or directed-energy programs and want the opportunity to build something from the beginning, we’d like to talk
