Job Title: Sr Spec Systems Engrg Field Testing Lead

Job Code: 42407

Job Location: Yorba Linda CA

Job Schedule: 4/10: Employees work 10 hour days 4 days a week with every Friday off

Job Description:

Navigation Solutions delivers advanced military GPS and broader Position Navigation and Timing (PNT) capabilities that support mission requirements across weapon systems ground platforms airborne assets maritime systems and space environments. The engineer will collaborate closely with cross functional teams to ensure these systems meet performance reliability and integration requirements across all operational domains.
A key responsibility of this role is field testing GPS receivers in contested and threat representative environments. This includes planning executing and analyzing tests that assess receiver performance under conditions such as jamming spoofing intentional interference and degraded signal scenarios. The engineer will validate real world robustness characterize system behavior under mission-relevant stressors and ensure compliance with stringent military performance standards. These field activities require travel and coordination with external test ranges customers and mission partners.
Navigation Solutions products are engineered to provide resilient PNT performance for the warfighter operating in denied or degraded environments. This role directly ensures that GPS receivers and simulators maintain mission effectiveness when exposed to adversarial threats and operational challenges.

Essential Functions:

Develop and integrate Special Test Equipment (STE) for Functional Qualification Testing (FQT) Environmental Testing EMI testing and manufacturing support.

Perform hands-on system integration test deployment and execution roles.

Proficient in the operation and understanding of wireless/RF test equipment such as signal analyzers signal generators and spectrum analyzers.

Develop test automation including equipment drivers debug tools automation scripts database interfaces and reporting tools.

Collaborate with engineering quality assurance and production teams to ensure a smooth testing process and address issues discovered during Acceptance Test Procedures (ATP) and Factory Acceptance Tests (FAT).

Plan and set up complex production lab environments for end-to-end automation including knowledge of lab networks and power supplies.

Plan coordinate and execute field tests of GPS receivers in contested degraded and threatrepresentative environments including jamming spoofing and interference scenarios.

Develop detailed field test plans procedures and instrumentation setups to evaluate receiver performance resiliency and compliance with military requirements.

Operate and configure portable RF GPS and PNT test equipment during field missions ensuring accurate signal capture logging and analysis.

Collect analyze and interpret large datasets from field events to assess receiver performance identify anomalies and characterize system behavior under operationally relevant stressors.

Interface with external test ranges government partners program stakeholders and mission partners to schedule and conduct field activities.

Ensure proper handling configuration and verification of test assets including GPS receivers antennas and rangeprovided instrumentation.

Document field results through reports presentations and internal briefings to support design updates readiness reviews and customer deliverables.

Provide technical feedback to system engineering firmware software and hardware teams to drive corrective actions for issues discovered during field testing.

Support creation and refinement of threat models test profiles and operational scenarios to ensure alignment with modern adversarial techniques.

Assist in maintaining readiness of fieldtest kits including calibration of instruments verification of datalogging systems and management of testspecific hardware.

Must have a US Secret security clearance

Qualifications:
