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.
DEVELOPMENT ENGINEER II
Development Engineers deliver across a broad set of vehicle domains including structural (i.e. Propellant tanks, interstages, fairings), mechanical (i.e. stage separation, landing, aerodynamic control), fluid (i.e. pressurant, propellant management, ignition, HVAC), and thermal (i.e. thermal protection) systems.
This role will focus on vehicle structures, working closely with analysis and manufacturing engineers to help support the development of concepts, detailed designs, and drawing packages for metallic and composites components & assemblies. This role requires close work with more experienced engineers to deliver project contribution to the expectations of the company.
We are currently looking for candidates with experience in the following areas:
- Composites
- Moving Mechanical Assemblies
- Metallic Structures
- Fluid Routing
- Materials Engineering
WHAT YOU'LL GET TO DO:
- Produce & rapidly iterate conceptual designs in CAD for aspects of primary and secondary metallic and composite structures across the Neutron launch vehicle.
- Own design aspects of elements including composite inserts, laminates, joint details, metallic interfaces, and secondary structural elements, working closely with analysts to ensure designs are appropriately sized and structural & thermal requirements are met.
- Support with creating drawing packages & technical reports, working directly with the production team to ensure design for manufacture is maintained throughout the process.
- Produce test jigs / fixtures to aid with fabrication, assembly, and development testing of components & assemblies.
- Proactively identify and solve technical challenges to allow projects to proceed at pace.
