<p><strong>NEUTRON</strong></p>

<p>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.</p>

<p><strong>THERMOFLUIDS ANALYST</strong></p>

<p>We're looking for a <strong>Thermofluids&nbsp;Analyst</strong>&nbsp;to&nbsp;join&nbsp;our&nbsp;Thermofluids&nbsp;Analysis team,&nbsp;responsible for&nbsp;all internal&nbsp;thermodynamics &amp; fluids mechanics&nbsp;modelling &amp; simulation&nbsp;across&nbsp;our&nbsp;Electron &amp; Neutron&nbsp;vehicles.&nbsp;&nbsp;</p>

<p>This role is based in Auckland, New Zealand.&nbsp;</p>

<p><strong>WHAT YOU'LL GET TO DO:</strong></p>

<ul>

<li>Propellant

<ul>

<li>Own propellant delivery and management—covering temperatures and stratification, cavitation margin, transients, slosh, PMD design, settling, and in-space thermodynamics—and perform CFD of internal fluid systems (compressible and incompressible flow)</li>

<li>Address depletion, residuals, and utilisation control, and own tank pressurisation, including pressurant budgets, in-tank thermodynamics, and autogenous system sizing</li>

<li>Design RCS systems, including N2 budget, thruster specification, and flow modelling of valves and lines</li>

</ul>

</li>

<li>Thermal

<ul>

<li>Own system thermal design across ground, flight, and in-space operations, including TPS response, compartment thermals, insulation, and component thermal modelling</li>

<li>Perform heat transfer simulations (conduction, convection, radiation) and characterise thermal environments, developing design guidelines and mitigations</li>

<li>Model HVAC and cavity conditioning (flow/temperature specification, pressure drop, flammability, cleanliness, humidity) and support payload integration and customer ITAs</li>

</ul>

</li>

<li>Analysis &amp; Data

<ul>

<li>Work closely with design and test engineers to iterate design concepts, determine test requirements, and demonstrate positive margins through numerical analysis, and physical test</li>

<li>Process and interpret ground test and flight data—confirming MPE bounds, detecting out-of-family results, and resolving sensor configuration issues&nbsp;</li>

</ul>

</li>

</ul>

<p><strong>YOU'LL BRING THESE QUALIFICATIONS:</strong></p>

<ul>

<li>A degree in Mechanical or Aerospace Engineering or similar field</li>

<li>1+ years industry experience, ideally from&nbsp;the Aerospace, Automotive, or Marine industries</li>

<li>A keen physics and first principles-based approach to problem solving</li>

<li>Expertise&nbsp;with one or more industry standard CFD packages: Fluent, CFX, STAR-CCM+</li>

<li>Experience in engineering programming, especially using Python (including Python packages numpy, pandas,&nbsp;scipy, matplotlib, etc.)</li>

</ul>
