- Active TS/SCI security clearance at the time of hire.
- Experience with GEOINT workflows.
- Experience with system-of-systems testing.
- Experience with test automation software such as JMeter, JUnit, TestComplete, or comparable tools.
- Experience analyzing system requirements, concepts of operations, system descriptions, or comparable technical documentation to develop test and evaluation approaches.
- Experience developing, maintaining, and executing test plans, test procedures, test cases, or evaluation criteria.
- Experience collecting, analyzing, interpreting, and documenting test data and technical results.
- Ability to identify functional or performance problems, investigate contributing factors, and recommend practical corrective actions.

- Experience supporting test readiness activities, demonstrations, formal test events, or comparable evaluation activities.
- Ability to document test status, results, risks, impediments, and recommendations for technical and program stakeholders.
- Experience coordinating test activities across engineering disciplines or external test organizations.
- Understanding of quality, reliability, verification, validation, and configuration-controlled test practices.
- Ability to independently lead defined test and evaluation efforts within an assigned technical scope.
- Strong technical writing, analytical, and verbal communication skills.
Preferred Qualifications
- Experience supporting U.S. Government, defense, intelligence, space, or other mission-critical programs.
- Experience developing or contributing to formal Government Test & Evaluation documentation, including Test & Evaluation Strategies, Test & Evaluation Master Plans, Event Test Plans, Test Readiness Assessments, or T&E Reports.
- Experience supporting system-level verification and validation across hardware, software, or integrated mission systems.
- Experience defining or improving test processes, quality-control standards, reliability practices, or broader testing programs.
- Experience providing independent technical observation or acting as a witness during system demonstrations or formal test events.
- Experience supporting acquisition, developmental test, operational test, or system acceptance activities.
