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.
While other companies talk about it, we do it!
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.
SYSTEMS ENGINEER – MECHANICAL
As a Systems Engineer, you'll sit at the intersection of Neutron's mechanical and fluid systems, working across Thermofluids, Propulsion, GNC, and Structures to architect the launch vehicle to meet program objectives. You will drive topics such design topics and risks to resolution. Defining operating processes where they don’t exist today.
You will deliver cross functional support to teams to align Neutron’s mechanical and fluid system designs with the program’s strategy, requirements, operations and technical maturity phases.
Systems Engineers are strong communicators, who combine expertise in technical assessment to optimise system performance, and possess a depth of knowledge to be able to define process excellence for the project.
Successful candidates will thrive in ambiguity, and are excited to work in a small, high performing team focused on continued learning and growth. This position is ideal for a multidisciplinary engineer keen to hit the ground running in support of a complex project from critical design through to integration and launch.
This role is based in Auckland, New Zealand.
Join a driven team that’s tackling challenging projects, delivering on exciting missions, and making an impact on the future of space!
WHAT YOU'LL GET TO DO:
- Drive cross-functional teams to ensure mechanical and fluid systems integrate seamlessly to deliver the vehicle's objectives, proactively identifying system-level impacts to allow seamless integration.
- Work closely with design teams to verify requirements through analysis and test, ensuring that verification artefacts are documented and linked to requirements.
- Take ownership of emergent systems that don't have a natural home; architecting the solution and driving it through design, verification, and implementation.
- Define and improve interface management processes, closing the gap between early project tools and production suitable systems.
