Senior Radio Frequency Engineer (Contingent)

KIHOMAC•Oklahoma City, OK

About The Position

This position is contingent upon contract award. The Senior Radio Frequency Engineer will lead High Power Amplifier Circuit Card Assembly redesign to achieve strict Form‑Fit‑Function‑Interface compatibility. Responsibilities include planning and executing measurements of GFP/GFI hardware, deriving and verifying baseline parameters, developing correlated RF and thermal simulation models, and evaluating device topologies. The role also involves authoring and maintaining requirements in MBSE, producing SSS and ICS with full traceability, owning EMI/EMC and environmental planning, and preparing for SRR/PDR with Government stakeholders. Additionally, the engineer will coordinate U.S. vendor market surveys, manage NDAs, integrate supplier inputs, collaborate with program management on PMP and IMS, and mentor team members.

Requirements

Bachelor’s Degree in relevant engineering or science discipline required
8+ years experience designing, testing, and qualifying RF power amplifiers for radar or high‑power pulsed applications (L‑band preferred)
Hands‑on experience with BJT/LDMOS/GaN device selection, biasing, matching networks, and microstrip layout
Proficiency building high‑fidelity RF and thermal models (e.g., Ansys HFSS/Icepak) and correlating to measured data
Requirements engineering using MBSE tools (e.g., Cameo)
Authoring System/Subsystem Specifications and Interface Control Specifications
EMI/EMC planning and pre‑qualification per MIL‑STD‑461; environmental and ESS testing per MIL‑STD‑810
Must be a US citizen
If selected candidate does not have an active Clearance at level Secret or higher, one will be obtained upon hire
