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. NEUTRON  Rocket Lab’s Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life. From designing and testing Neutron’s structures and components, to firing up its new Archimedes engines, to setting up Neutron’s launch pads and test sites across the United States, joining the Neutron team is your opportunity to help launch a new large rocket for the very first time.  PRINCIPAL STAGE FLUIDS ENGINEER As a Principal Stage Fluids Engineer, Neutron owns the design, build, test, and review of multiple fluid systems across the Neutron launch vehicle. Our team owns all plumbing and systems between the tanks and the engines. Your work within the Fluid Systems department will turn vehicle-level requirements into a fluid network that enables Neutron to operate with aircraft-like reusability and reliability. WHAT YOU’LL GET TO DO • Design plumbing systems, components, and their secondary structures. Provide feedback to your peers on their designs, drawings, and methodology. • Analyze these systems and components in the harsh and dynamic environments of launch. Review and provide feedback for critical structural analysis of fluid components and systems. • Model these systems to characterize and predict system behavior at all conditions. Understand and interpret models of others and work to improve efficacy of modelling. • Test and qualify these systems, components, and modules. • Manage requirements, realization, and implementation of systems in the larger launch vehicle context. • Integrate your hardware into the vehicle. • Review data from component, system, and vehicle level testing to optimize and improve future designs. • Collaborate with components, propulsion, structures, mechanical, operations, and flight software teams to develop and define vehicle functions. • Create tools to enhance the team’s analysis capabilities, streamline workflow and optimize launch operations. • Set the standard for design, production, and testing processes. Enforce these standards across the program and beyond. • Mentor and grow your peers to strengthen the overall team. YOU’LL BRING THESE QUALIFICATIONS AS A PRINCIPAL STAGE FLUIDS ENGINEER: • Bachelor’s degree in Mechanical Engineering or relevant engineering discipline. • 12+ years of experience in a hardware rich environment. • Experience with fluid components design and usage for valves, pressure vessels, flex elements & fittings. • Experience with DfM/DfAM, machining processes, and welding processes with a proven understanding of mechanical drafting and GD&T. THESE QUALIFICATIONS WOULD BE NICE TO HAVE: • 8+ years of experience in a fast-paced aerospace environment where you have completed difficult projects while collaborating effectively with other key groups. • Strong understanding of how to design for classic aerospace constraints: minimizing mass while maintaining manufacturability, function, and low costs. • Ability to earn trust, maintain positive professional relationships, & contribute to a culture of inclusion. • Experience working with a distributed team across the globe. • Advanced degree in a fluid mechanics-heavy field. • Experience with oxygen, methane, and/or cryogenic systems. • Experience using Siemens NX & Teamcenter. • Demonstrated ability to rally a team to make & execute good decisions in a fast-paced environment with limited information. • Experience with Aerospace Processes, Standards, and Workflows, from JIRA to AS9100. 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   Anticipated annual equity grant value is designed around function, level, experience, and other factors; realized value depends on vesting and stock-price performance.

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.    Important information: FOR CANDIDATES SEEKING TO WORK IN US OFFICES ONLY: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), Rocket Lab Employees must be a U.S. citizen, lawful U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum, or be eligible to obtain the required authorizations from the U.S. Department of State and/or the U.S. Department of Commerce, as applicable.
