Job description

Development Engineer II - Thermal Protection Systems

Auckland, NZ

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.

DEVELOPMENT ENGINEER II – THERMAL PROTECTION SYSTEMS

As a Development Engineer II specializing in Thermal Protection Systems (TPS), you'll be at the forefront of designing cutting-edge vehicle structures that withstand extreme environments. Collaborating closely with analysis, design, and manufacturing teams, you'll transform innovative concepts into detailed designs and precision-engineered components using advanced metallic and composite materials. Your expertise in testing, control, modelling, and analysis will be critical to ensuring the performance and reliability of these systems. This is your opportunity to push the boundaries of engineering and contribute to the creation of next-generation aerospace technologies!

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 innovation by creating and rapidly iterating conceptual designs in CAD for cutting-edge thermal protection systems and subassemblies across metallic and composite structures for the Neutron launch vehicle.
• Design critical elements such as composite assemblies, material stack-ups, joint details, seals, fastening solutions, and metallic interfaces, while collaborating closely with analysts to ensure structural and thermal requirements are met with precision.
• Lead the creation of detailed drawing packages and assembly models, working hand-in-hand with the production team to ensure seamless design-for-manufacture throughout the process.
• Own, maintain, and manage analysis tools and methods for 1D and 2D/3D analysis of thermal performance of design features.
• Design and implement hardware, instrumentation, and test articles to streamline development testing and correlation of models, enabling efficient validation of components and assemblies.
• Support TPS solutions hands-on through qualification, manufacturing, and integration activities via direct engagement with interfacing technical teams.
• Collaborate with Thermofluids and structures teams as primary interface on aerothermal and TPS related tools and topics
• Inspire and empower the next generation of engineers by providing mentorship and technical guidance to junior team members, leveraging and creating technical documentation to enhance capabilities through analysis tools and thermal testing procedures.

YOU’LL BRING THESE QUALIFICATIONS:

• Aerospace, mechanical or mechatronic engineering degree or equivalent qualification
• 2 - 4 years of design experience, designing high performance mechanical or thermal systems
• A strong understanding of material science, thermodynamics, heat transfer, and aerodynamics, with specific focus on their application to TPS
• 2 years experience with CAD software and modelling tools for mechanical and thermal design and analysis
• The ability to work under pressure and to tight deadlines
• Excellent communication skills and the ability to work well within a team environment
• Sound analytical skills and the ability to see the big picture and making connections and appropriate decisions
• Have tenacity, a can-do attitude, and the ability to think quickly and make accurate judgements

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

• Strong understanding of engineering fundamentals (mechanics of materials, thermodynamics, material property characterization, design best practices, analysis methods, and manufacturing processes)
• Advanced skills with Python and MATLAB
• Familiarity with CFD – StarCCM, Ansys Fluent, COMSOL or equivalent
• Familiarity with engineering trade studies and material selection
• Experience with thermal testing, data acquisition, test hardware, and test planning
• Experience in one of the following domain areas:
  • Composite structures
  • Metallic structures
  • Materials characterization and testing
  • Transient thermal response modelling
  • High temperature and insulative materials
  • Hands-on experience with TPS material, technologies, and manufacturing
  • Spacecraft or launch vehicles

NOTE: Along with a CV and Cover Letter, please attach a recent CAD portfolio with your application for review.

WHAT TO EXPECT

We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. 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.
