Field Engineer III

JT4, LLC provides engineering and technical support to multiple western test ranges for the U.S. Air Force, Space Force, and Navy under the Joint Range Technical Services Contract, better known as J-Tech II. JT4 develops and maintains realistic, integrated test and training environments and prepares our nation's war-fighting aircraft, weapons systems, and aircrews for today's missions and tomorrow's global challenges. **JOB SUMMARY - ESSENTIAL FUNCTIONS** A Field Engineer III performs as a lead on more complex field engineering assignments and performs a variety of engineering assignments involving technology applications involved in the installation, operation, testing, and maintenance of complex electronic/mechanical equipment and systems. Employee will be responsible for the following functions/duties: - Apply knowledge of design specifications for more complex systems/projects - Coordinate and work closely with other engineering, logistics, financial, and program management disciplines to define system specifications and requirements - Verify and comply with engineering documentation standards and test procedures - Prepare, deliver, and submit technical papers and perform engineering studies - Support development of technical proposals and provide comments on technical content and level of effort of the proposed scope of work - Develop, maintain, and produce technical documentation and system/subsystem specifications - Direct interface and liaison with customers at all levels from quotation to final design and test activities, design reviews, and technical working group meetings to comply with requirements and specifications - Conduct site visits, experimental investigations and analyze engineering problems, propose solutions and alternatives, and provide recommendations - Perform other job-related duties, as required **RANGE POSITION DESCRIPTION** The candidate filling this position will be responsible for the operation, maintenance, troubleshooting, repair, and modification of electronic instrumentation systems and associated support equipment used in test, measurement, and operational avionics environments. This position requires independent problem-solving skills, attention to detail, and the ability to work effectively in both backshop and field environments. This role requires heavy lifting as necessary to support shop operations. The potential candidate must possess a strong working knowledge of electronic systems and principles, including signal flow, circuit operation, fault isolation, and system-level troubleshooting down to the circuit board level utilizing specialized equipment such as a Huntron Tracker, Oscilloscope (O-scope), and multimeters. The position requires experience with radio frequency (RF) systems, RF hazard awareness, transmission lines, antennas, and associated test equipment used to evaluate and maintain communications and telemetry systems, including radar beacon transponder tuning. Candidates must demonstrate proficiency in wiring harness fabrication and repair (including Cannon-plug repair), connector installation and termination techniques, cable continuity verification, and the interpretation of technical drawings, schematics, and wiring diagrams. Experience with industry-standard connector types and cable assembly practices is highly desirable. Candidates must be able to perform mechanical teardown and reassembly strictly adhering to technical data. A thorough understanding of the Global Navigation Satellite System (GNSS), including system operation, receiver functionality, signal characteristics, and related support equipment, is required. The individual will be expected to support GNSS-based instrumentation and positioning systems in operational, developmental, and troubleshooting capacities, including the programming of data cards for real-time recording under rigid Range parameters. The position also requires strong computer skills, including familiarity with computer hardware, networ…
