Rocket Lab Optical Systems, part of Rocket Lab's Space Systems division, is seeking a Principal Engineer for Space Payloads to lead the design, development, and integration of next-generation space-based electro-optical sensor systems. The division has enabled over 1,700 missions ranging from interplanetary exploration to national security and defense initiatives, with work spanning missions to the Moon and Mars in partnership with NASA, the Space Development Agency, and the U.S. Space Force.
In this role, you will serve as the definitive technical authority for space-based payload programs, guiding multi-disciplinary teams through all development phases from requirements definition through integration, test, and sustainment. You will own the technical baseline across systems engineering, hardware, software, and test; chair program gate reviews (SRR through TRR); and direct the development and integration of architectures spanning payload, ground systems, and mission operations. Your responsibilities include overseeing engineering performance to deliver on cost, schedule, and technical objectives, including subcontractor oversight; enforcing standards and processes while advancing Model-Based Systems Engineering (MBSE) and Digital Engineering; managing the program Risk Register; serving as the primary technical interface with customer technical teams and leadership; and mentoring engineers across disciplines to foster collaboration and technical excellence.
You will also contribute to proposals, technical volumes, and customer-facing reviews, helping shape future opportunities for the organization. This role offers direct impact on national security by delivering advanced space capabilities to Department of Defense and Intelligence Community customers.
