Rocket Lab Optical Systems is seeking a Principal Integration & Test Engineer to lead integration, alignment, calibration, and verification of advanced electro-optical/infrared (EO/IR) payloads for spaceborne sensor systems supporting national defense space missions. This is a hands-on, highly technical role based in Tucson, AZ.
You will own the full lifecycle of optical payload integration and testing, including optical bench setup, metrology, environmental test readiness, and performance validation. Key responsibilities include:
• 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
• Develop and refine test procedures, optical characterization methods, and performance-validation processes
• Support environmental tests (TVAC, thermal-vacuum; vibe, vibration; shock), monitor optical performance, and ensure compliance with mission requirements
• Drive resolution of integration issues, test anomalies, and optical performance deviations
• Work cross-functionally with Mechanical, Electrical, Systems, and AIT (Assembly, Integration, and Test) 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
Rocket Lab's Space Systems division has enabled more than 1,700 missions, ranging from interplanetary exploration and in-space manufacturing to national security and defense initiatives.
