INTEGRATION & TEST ENGINEER II

Rocket Lab's Optical Systems division solves mission-critical space domain and Intelligence, Surveillance, and Reconnaissance (ISR) challenges for Department of Defense (DoD) and Intelligence Community (IC) customers. Our vision is to revolutionize the space-based payload market with innovative and novel designs for space, terrestrial, and airborne environments. Building on more than 20 years of electro-optical and infrared systems innovation from Geost, Optical Systems delivers solutions to the warfighter for responsive, scalable sensing solutions across all orbital domains.

As an Integration & Test Engineer II based at our Optical Systems site in Tucson, AZ. You will play a key role in the integration, alignment, calibration, and verification of advanced EO/IR payloads that support national defense space missions. This role is hands-on and highly technical, involving optical bench setup, metrology, environmental test readiness, and performance validation. You will work cross-functionally with Mechanical, Electrical, and Systems Engineering teams to ensure precise optical performance through every integration and test phase. Join a driven team of pioneers relentlessly tackling challenging projects, delivering on the impossible, and making an impact on the future of space!

WHAT YOU'LL GET TO DO:

• Lead integration, alignment, calibration, and verification activities for advanced EO/IR optical payloads used in spaceborne sensor systems
• Execute hands-on optical integration tasks including optical bench setup, alignment, metrology, and environmental test readiness—we build beautiful things
• Develop and refine test procedures, optical characterization methods, and performance-validation processes
• Support environmental tests (TVAC, vibe, shock), monitor optical performance, and ensure compliance with mission requirements
• Drive resolution of integration issues, test anomalies, and optical performance deviations—we hustle and we do the impossible
• Work cross-functionally with Mechanical, Electrical, Systems, and AIT teams to ensure seamless optical-mechanical-electrical integration
• Support customer reviews, data packages, and technical briefings
• Identify opportunities to improve alignment methods, test tooling, and data-analysis workflows
