About the Role

We're looking for an Integration & Test Engineer to support the assembly, integration, and verification of large space structures and flight hardware. You'll work closely with design engineering, manufacturing, and test teams to ensure hardware is integrated safely, correctly, and efficiently. This role spans both hands‑on support on the build floor and technical development of test procedures, system checkouts, and integrated operations.

As an Integration & Test Engineer, you'll help define test setups, support mechanical/electrical/fluid system bring‑up, resolve integration issues, and ensure hardware meets flight‑ready requirements.

Responsibilities

• Support mechanical, electrical, and fluid system integration for flight and ground hardware
• Develop, refine, and execute test procedures for subsystem and system‑level tests
• Support functional checkouts, leak checks, pressure tests, electrical continuity tests, and integrated system operations
• Drive preparation of test equipment, ground support equipment (GSE), sensors, and instrumentation
• Assist in diagnosing integration issues and support corrective actions with engineering and technicians
• Review engineering drawings, electrical schematics, and interface control documents (ICDs)
• Ensure hardware is integrated in compliance with safety standards, configuration control, and quality requirements
• Support test data review, anomaly documentation, and issue tracking
• Participate in lifting, mating, and alignment operations for large assemblies
• Collaborate with manufacturing, design, quality, and operations teams during build‑to‑test handoffs
• Contribute to improvements of integration processes, test methods, and test documentation

About You

You enjoy working at the intersection of engineering design and real hardware. You're hands‑on, detail‑oriented, and comfortable supporting fast‑paced operations on the build and test floor. You can troubleshoot unexpected issues with a systematic approach, communicate clearly, and adapt quickly to changing priorities. You respect procedure but aren't afraid to recommend improvements.

Required Attributes

• 3–5+ years of experience in integration, testing, or systems‑focused engineering
• Experience with mechanical, electrical, or fluid system assembly or checkout
• Familiarity with test execution involving pressure systems, electrical systems, or avionics
• Ability to interpret engineering drawings, wiring diagrams, and fluid schematics
• Experience writing or executing test procedures
• Strong problem‑solving skills using first‑principles and hands‑on troubleshooting
• Bachelor's degree in Mechanical, Aerospace, Electrical, or related engineering field
• Comfortable working in fast‑paced environments with shifting priorities
• Ability to lift up to 25 lbs and work around large hardware
• Willingness to work evenings/weekends or travel occasionally to support critical operations
• This role will support programs for U.S. Government customers, including national security and defense-related missions. Candidates must be willing to work on Civil, Commercial, and Defense-related projects.

Bonus Points for

• Experience with integration or test of spacecraft, launch vehicles, aircraft, or other high‑reliability systems
• Familiarity with environmental testing (thermal, vibration, shock, pressure, EMI/EMC)
• Experience with leak testing, pressure systems, hazardous operations, or GN2/He/propellant systems
• Knowledge of instrumentation, sensors, and data acquisition systems
• Experience developing work instructions or supporting technicians during integration
• Experience in safety‑critical or configuration‑controlled environments
• Experience performing hands‑on mechanical or electrical assembly
