Role Overview

We are seeking a mid-level RF & Antenna Design Engineer to design, develop, and validate RF and antenna solutions for aerospace, defense, SATCOM, electronic warfare, and commercial vehicle platforms, including rail and marine applications. This role is for an engineer who combines strong RF fundamentals, hands-on testing experience, and disciplined engineering documentation practices to deliver reliable, fielded hardware.

This is a technical individual-contributor role. While it does not include people management responsibilities, engineers at this level are expected to demonstrate design ownership, contribute to design reviews, and provide informal technical mentorship.

What You Will Do

RF & Antenna Design

· Design antennas and supporting RF circuitry from VHF through 6 GHz (exposure up to 26 GHz as needed)

· Perform EM simulation and RF analysis using industry-standard tools

· Derive requirements and develop RF/antenna architectures from system-level needs

· Develop, tune, and optimize prototypes for performance, efficiency, and manufacturability

Validation & Test

· Define and execute design verification and validation plans

· Perform antenna measurements including impedance, radiation patterns, gain, and efficiency

· Utilize RF lab equipment (VNA, spectrum analyzer, signal generator, etc.)

· Correlate measured data to simulation models

· Support antenna range testing, EMI/EMC testing, and environmental qualification

Hardware Implementation & Production Support

· Apply knowledge of PWB materials, dielectric properties (Dk/Df), and RF loss mechanisms in high-frequency designs

· Demonstrate working understanding of controlled impedance design, microstrip structures, and grounding techniques

· Collaborate with layout and mechanical teams to ensure sound RF implementation

· Support prototype fabrication, including hands-on build activities

· Create and maintain BOMs and design documentation

· Support transition from prototype to production and assist with field or production troubleshooting

Standards & Documentation

· Support designs intended to meet DO-160, MIL-STD-810, MIL-STD-461, or similar standards

· Produce clear engineering documentation and participate in design reviews

Required Qualifications

· Bachelor’s degree in electrical engineering or related field

· 2–7 years of RF and/or antenna engineering experience

· Demonstrated experience designing RF and antenna hardware from VHF through 6 GHz

· Hands-on experience with EM simulation tools

· Practical RF lab experience using VNAs and related test equipment

· Strong understanding of antenna theory, impedance matching, bandwidth optimization, and efficiency

· Working knowledge of phased array fundamentals, including array factors and amplitude/phase weighting techniques

· Ability to clearly document and communicate technical work, fluent with Microsoft 365

· Must be a U.S. Person as defined by ITAR, able to obtain and maintain a U.S. security clearance

Preferred Qualifications

· Experience designing or supporting systems up to 26 GHz

· Experience with phased array implementation and beam steering, including practical weighting methods

· Aerospace, defense, SATCOM, EW, rail, or marine industry experience

· Experience transitioning RF or antenna designs into production

· Hands-on prototype fabrication experience (machining and/or soldering)

· MATLAB or Python for RF analysis or automated test support
