ABOUT ROCKET LAB

Rocket Lab is an end-to-end space company delivering responsive launch services, complete spacecraft design and manufacturing, payloads, satellite components, and more – all with the goal of opening access to space. The rockets and satellites we build and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations.  

Our Electron rocket has become the second most frequently launched U.S. rocket annually and has delivered more than 230 satellites to orbit, all while we work to develop Neutron, our upcoming medium-lift, reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds our extensive line of satellites, payloads, and their components, including spacecraft that have been selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope. 

SPACE SYSTEMS

At Rocket Lab, we’re not just launching rockets — we're building the future of space. Our Space Systems team builds everything from complete spacecraft, precision payloads to the components and subsystems that allow them to thrive in space, like solar panels, flight software, star trackers, optical systems, separation systems, radios, and more.

Our Space Systems team has enabled more than 1,700 missions, ranging from interplanetary exploration, in-space manufacturing to national security and defense initiatives. The team has 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 them get to space — our world class Space Systems team is empowering some of the boldest and most ambitious space missions.

PRINCIPAL ENGINEER, SPACE PAYLOADS – ACTIVE SECRET/TOP SECRET CLEARANCE

Rocket Lab’s Optical Systems (RLOS) 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 a Principal Engineer based at our Optical Systems site in Tucson, AZ, you will lead the design, development, and integration of next-generation space-based electro-optical sensor systems. As the definitive technical authority, you’ll guide a multi-disciplinary team through all phases of development – from requirements definition to integration, test, and sustainment – ensuring mission success while advancing innovation. This role offers the opportunity to make a direct impact on national security by delivering advanced space capabilities to our customers. 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:

• Own the technical baseline for programs: Serve as the technical authority across systems engineering, hardware, software, and test, ensuring requirements are achieved and the system delivers mission value
• Lead critical reviews: Chair program gate reviews from SRR through TRR, assessing design maturity, readiness, and risk posture
• Shape system architecture: Direct the development and integration of architectures spanning payload, ground systems, and mission operations
• Guide execution: Oversee engineering performance to deliver on cost, schedule, and technical objectives, including subcontractor oversight
• Champion engineering excellence: Enforce standards, processes, and quality while advancing Model-Based Systems Engineering (MBSE) and Digital Engineering
• Manage risk & opportunity: Own the program Risk Register, proactively mitigating risks and capturing opportunities to improve performance
• Engage with stakeholders: Act as the primary technical interface with customer technical teams, subcontractors, and RLOS leadership
• Support growth: Contribute to proposals, technical volumes, and reviews, helping shape future opportunities
• Mentor the next generation: Provide leadership and guidance to engineers across disciplines, fostering collaboration, knowledge transfer, and technical excellence

• Five+ years developing command & control, mission planning, or tactical ground systems for space assets
• Experience with CONOPS development and enterprise-scale architecture(s)
• Knowledge of advanced data exploitation, machine learning, and Automatic Target Recognition (ATR)
• Experience integrating multi-disciplinary engineering efforts across suppliers and subcontractors
• Leadership in the design, production, and integration of large-scale defense or aerospace systems
• Hands-on experience applying Model-Based Systems Engineering (MBSE) methods
• Track record of achieving technical, cost, and schedule commitments as a chief engineer or technical lead
• Excellent communication skills, with the ability to present complex technical solutions to executives, customers, and non-technical audiences
• Ability to build consensus across diverse stakeholders and make sound decisions under uncertainty

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.
