Must have an active US Government Secret clearance (with a background investigation within the past 6 years or enrolled into Continuous Evaluation).
Must have the ability to obtain and maintain Special Access Program (SAP) clearance, within a reasonable amount of time as determined by business needs.
Experience in systems integration and test for complex aerospace/defense or mission systems (hardware + software).
Hands-on with HIL and/or SIL, including configuration control and data/instrumentation systems.
Experience developing/executing test procedures and analyzing data for flight or mission systems.
Demonstrated ability to solve complex test problems with ingenuity and creativity.
Strong written and verbal communication skills.
U.S. Citizenship is required for all positions with a government clearance and certain other restricted positions.

Nice To Haves

Experience with flight test and airworthiness/mission system Hardware/Software certification (e.g., flight release, safety of flight, mission approval).

Demonstrated use of “test like you fly” in lab and/or flight configurations.
Experience with test automation/data analysis tools (e.g., Python, MATLAB, LabVIEW).
Experience as technical lead or primary technical contact with customers/partners.

Responsibilities

Perform first-time integration and checkout of new integrated hardware and software capabilities.
Plan, develop, dry run, and perform formal execution of test procedures that produce certification-quality evidence.
Lead HIL/SIL testing; define and maintain representative “test like you fly” configurations (hardware, software, loads, instrumentation).
Perform data analysis of recorded data to support pass or fail disposition of success criteria.
Decompose system/software requirements into test objectives; ensure traceability from requirements through test results and certification artifacts.
Develop and review test plans, procedures, cards, and reports for verification, validation, and certification.
Analyze data, identify anomalies, support or lead root-cause investigations, and recommend corrective actions for airworthiness and mission capability.
Coordinate with and support systems engineering, software, hardware, airworthiness, safety, production, and ground/flight test operations to resolve issues and keep lab, ground, and flight test aligned.
Mentor less-experienced engineers in systems test, HIL/SIL methods, and certification-focused verification.
