Principal Systems Engineer

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 Principal Systems Engineer for Rocket Lab Optical Systems in Tucson, AZ, you will be involved throughout the entire lifecycle of advanced space payloads in support of Tranche 3 of the U.S. Space Development Agency's Proliferated Warfighter Space Architecture.

WHAT YOU’LL GET TO DO:

• Support the development of system architecture for space-based optical instruments, subsystems, and payloads on airborne and space platforms, with emphasis on electrical architecture and controls integration
• Define, decompose, and manage system requirements with focus on electrical behavior, control functions, subsystem interactions, and overall system performance
• Develop and maintain technical documentation including architecture descriptions, interface control documents, electrical interface definitions, concepts of operations, state and mode descriptions, test plans, and verification artifacts
• Support development of electrical and functional architectures, including command and telemetry flow, power distribution, control logic, signal paths, timing, synchronization, and subsystem interaction
• Collaborate with hardware, software, firmware, and test teams to ensure the electrical architecture and controls implementation align with system requirements and mission intent
• Support the development, integration, and testing of space payloads to be integrated on spacecraft platforms
• Support hardware and software development teams with system-level test planning, debugging, integration, and execution of verification procedures; analyze data and recommend design refinements
• Participate in hardware and software verification and validation activities related to system behavior, electrical performance, controls implementation, and interface compliance
• Support architecture trades involving sensors, motor control, embedded electronics, power systems, command and data handling, and subsystem interfaces
• Participate in technical interchange meetings and project discussions with internal teams, customers, and external partners as needed
• Identify, assess, and help mitigate technical risks related to electrical architecture, controls implementation, and subsystem integration
• Support travel or off-site work as needed
• Perform other duties as assigned

QUALIFICATIONS YOU’LL BRING AS PRINCIPAL SYSTEMS ENGINEER:

• Bachelor’s degree in electrical, systems, or aerospace engineering; or other technical discipline
• 12+ years of engineering experience, including 3+ years supporting development programs and 2+ years in technical leadership, CAM, IPTL, or equivalent role
• Demonstrated systems engineering experience with emphasis on electrical architecture, subsystem integration, and controls focused development
• Strong electrical engineering background supporting complex aerospace, payload, avionics, or instrument systems
• Experience developing system requirements, interface definitions, and verification approaches for complex systems
• Strong background in electrical interfaces, control functions, avionics integration, or subsystem architecture
• Experience with requirements management and modeling tools such as JAMA, DOORS, Cameo, or similar tools
• Experience working across hardware, software, and firmware development throughout the lifecycle
• Familiarity with command and telemetry interfaces, power architectures, signal interfaces, timing, synchronization, and control logic
• Experience supporting integration and test, including troubleshooting electrical or controls-related issues at the subsystem or system level
• Strong ability to read, interpret, and develop electrical, interface, and system technical documentation
• Familiarity with aerospace development standards, environmental testing, and mission assurance practices

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

• Current SSBI clearance
• EO/IR payload integration experience
• Experience with spacecraft bus interfaces, payload electrical integration, avionics architecture, or embedded electronics
• Experience with pointing, stabilization, gimbals, motion control, focus/control electronics, or other closed-loop control applications
• Experience defining or troubleshooting electrical architectures for sensors, actuators, motors, power systems, or embedded controllers
• Hands-on expertise leading troubleshooting and resolution of system-level electrical or controls-related issues
• Demonstrated experience working with minimal supervision in complex projects
• Experience in astronomy, physics, or remote sensing
• Excellent communication and interpersonal skills with the ability to collaborate with multidisciplinary teams and explain complex implementation processes to other organization members
• Strong communication, task management, and cross-functional coordination skills

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.
