  • Support the development, integration, and validation of AI‑enabled capabilities by collaborating with cross‑functional teams throughout the software development lifecycle
  • Participate in program milestone events, including customer meetings, government testing events, and discrepancy report review boards

Qualifications:

Desired:

  • At least 2 years of professional experience as an ELINT analyst
