Original job description

Description

POSITION OVERVIEW

We are seeking an experienced Position, Navigation, and Timing (PNT) and Navigation Warfare (NAVWAR) Test Engineer to lead the design, execution, and evaluation of resilient navigation test campaigns. Ideal candidates bring hands-on test and evaluation experience validating military avionics, guidance systems, and multi-sensor fusion architectures against active radio frequency (RF) jamming, meaconing, and sophisticated geo-spoofing threats.

KEY RESPONSIBILITIES

? Architect and execute hardware-in-the-loop (HITL), laboratory, and open-air flight test profiles simulating contested electromagnetic environments and multi-constellation GNSS spoofing attacks. ? Evaluate inertial navigation system (INS) aiding, M-Code military GPS receivers, controlled reception pattern antennas (CRPA), and anti-spoofing receiver autonomous integrity monitoring (RAIM) algorithms. ? Analyze high-rate telemetry, truth-source trajectories, and RF signal capture logs to quantify navigation degradation, time-to-alert metrics, and spoofing mitigation effectiveness. ? Develop automated test scripts and threat injection scenarios using industry-standard RF constellation simulators and software-defined radio (SDR) testbeds. ? Author comprehensive technical test reports, risk assessments, and system hardening recommendations for defense and aerospace engineering stakeholders.

REQUIRED QUALIFICATIONS

? Bachelor’s or Master’s degree in Electrical Engineering, Aerospace Engineering, Physics, or a related technical discipline. ? 5+ years of direct experience in PNT, GNSS/INS test and evaluation, or NAVWAR operations (such as service with the 746th Test Squadron / Central Inertial and GPS Test Facility). ? Deep technical fluency in GNSS signal structures (GPS L1/L2/L5, M-Code, Galileo, GLONASS), Kalman filtering, and tightly/ultra-tightly coupled GPS/INS architectures. ? Hands-on proficiency with RF signal generators, Spirent/Orolia GNSS simulators, spectrum analyzers, and data analysis tools (MATLAB, Python, or C++). ? Active Top Secret clearance with SCI eligibility.

PREFERRED QUALIFICATIONS

? Experience planning or executing open-air range testing at major DoD test ranges (e.g., White Sands Missile Range, Edwards AFB, or Eglin AFB). ? Familiarity with DoD PNT Open Systems Architecture (POSA) and Military Standard (MIL-STD) environmental/EMI/EMC testing.
