ABOUT ROCKET LAB

Rocket Lab is the end-to-end space company building rockets, spacecraft, and critical subsystems that keep the world connected, protected, expand humanity’s reach to the Moon, Mars, and beyond. We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us.

SPACE SYSTEMS

Rocket Lab’s Space Systems division builds complete spacecraft, precision payloads to the components and subsystems that allow them to thrive in space including solar panels, flight software, star trackers, optical systems, separation systems, and radios.

The Space Systems division has enabled more than 1,700 missions, ranging from interplanetary exploration, in-space manufacturing to national security and defense initiatives. We have built spacecraft, payloads, and components for missions to the Moon and Mars, working with partners including NASA, the Space Development Agency, and the U.S. Space Force. Whether it’s a single high-performance spacecraft, constellation, or the vertically integrated components that help get to space — our Space Systems division is empowering the boldest and most ambitious space missions.

SENIOR ASSEMBLY, INTEGRATION & TEST TECHNICIAN

Rocket Lab Optical Systems solves mission-critical space domain and Intelligence, Surveillance, and Reconnaissance challenges for Department of Defense and Intelligence Community 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, Rocket Lab Optical Systems delivers solutions to the warfighter for responsive, scalable sensing solutions across all orbital domains.

As a Senior Assembly, Integration and Test Technician for Rocket Lab Optical Systems in Tucson, AZ, you will have the opportunity to support Tranche 3 of the U.S. Space Development Agency's Proliferated Warfighter Space Architecture by integrating advanced electro-optical space payloads.

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

YOU’LL BRING THESE QUALIFICATIONS AS AN ASSEMBLY, INTEGRATION AND TEST TECHNICIAN:

• High school diploma and 4+ years of experience

• U.S. citizenship with ability to obtain and maintain a security clearance

• Experience in optical system integration, test, or verification

• Hands-on experience with optical alignment, metrology, interferometry, and imaging-system characterization

• Familiarity with optical benches, cleanroom practices, contamination control, and environmental testing

• Strong data analysis, troubleshooting, and problem-solving skills

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

• Experience with EO/IR payloads, infrared focal planes, or space-based sensor systems

• Experience implementing alignment procedures, test scripts, and verification plans

• Experience with automated test equipment or optical STE

This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production areas.
WHAT TO EXPECT

We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other’s backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.
