Hands‑on experience with flight‑test instrumentation (telemetry, high‑speed data acquisition, RF test equipment, DMMs, signal generators).
Proven flight‑test engineering experience, including test planning, execution, and data analysis for missile or aerospace systems.
Proficiency with Microsoft Office (Word, Excel, PowerPoint).
Proven record of documenting test plans, procedures, and reports
Active Secret clearance.

Nice To Haves

Excellent verbal and written communication skills; ability to present technical approaches, flight‑test results, and risk assessments clearly to diverse audiences.
Experience designing, developing, and implementing flight‑test methods, fault‑injection techniques, and specialized test equipment.
Ability to work independently with minimal direction and to lead larger flight‑test efforts.
Strong track record in writing flight‑test plans, procedures, and detailed post‑flight reports.
Knowledge of environmental‑stress‑screening (ESS) and reliability‑centered testing procedures for missile systems.
Demonstrated troubleshooting expertise in root‑cause‑corrective‑action (RCCA) analysis of flight‑test anomalies.
Experience in lab settings and bench set ups.

Responsibilities

Develop executable flight‑test plans that address technical specification verification, safety requirements, and range‑clearance constraints.
Work with internal and external customers to define instrumentation, telemetry, data‑capture, and post‑flight analysis requirements.
Coordinate flight‑range scheduling, launch vehicle integration, and support personnel to ensure safe and efficient test execution.
Conduct pre‑flight briefings, post‑flight de‑briefs, and real‑time flight‑test monitoring, including anomaly detection and mitigation.
Perform flight‑data collection, reduction, and dissemination to verification‑requirement stakeholders.
Author and publish flight‑test reports, data summaries, and certification packages that trace results back to program requirements.
Operate and troubleshoot flight‑test equipment such as telemetry receivers, high‑speed data loggers, RF spectrum analyzers, and signal generators.
Demonstrate expertise with data‑analysis tools such as MATLAB, LabVIEW, Excel, and scripting languages for rapid post‑flight processing.
Prepare briefings (Word, PowerPoint) for senior leadership, customer representatives, and technical review panels.
Continuously improve flight‑test processes, incorporate lessons learned, and implement best‑practice procedures.
Participate in and/or lead Technical Review Boards (TRRs), Flight Review Boards (FRBs), and other technical reviews related to flight testing.
