Senior Thermofluids Analyst

BUILDING NEUTRON AT ROCKET LAB: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.WHAT YOU'LL GET TO DO:As a Thermofluids Analyst in Rocket Lab's Analysis team you will contribute to the analysis, design, validation, and improvements of subsystems on the Neutron launch vehicle. Day to day, you will be expected to process flight data to determine the environments experienced by vehicle components, demonstrate positive margins against these environments through detailed analysis, and set the requirements to validate this analysis through test.Key Duties ABOUT ROCKET LABRocket Lab is a global leader in launch and space systems. The rockets and satellites we build and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations. Our Electron rocket has provided reliable access to orbit since 2018, becoming one of the most frequently launched rockets in the world. Neutron will be our next rocket on the launch pad, an advanced 13-tonne payload class, reusable rocket to launch the mega constellations of the future. Our space systems business includes our extensive line of satellites and components that have enabled more than 1,700 missions including the James Webb Space Telescope, NASA Psyche Mission, Artemis I, Mars Ingenuity helicopter, and more.Join our pioneering team and launch your career to new heightsBUILDING NEUTRON AT ROCKET LAB:Rocket Lab's Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life.

Success in this position will be measured by the knowledge and experience you bring to the role, your ability to lead development projects without supervision, and your ability to successfully collaborate across teams to deliver results.YOU'LL BRING THESE QUALIFICATIONS:A degree in Mechanical Engineering or similar field3+ year's industry experience, ideally from the Aerospace, Automotive or Marine industriesDemonstrated expertise with one or more industry standard CFD packages: Fluent, CFX, STAR-CCM+Experience in aerodynamics: predicting forces, moments and generating aerotables and aerodynamic controlTHESE QUALIFICATIONS WOULD BE NICE TO HAVE:Demonstrated experience with dynamic thermofluid systems:BuffetingAerotable evaluation & characterisationAerodynamic stability & controlPropellant Dynamics (slosh, flow instabilities, Pogo)Experience with mechanical systems in a relevant field (e.g. aerospace, automotive, marine)Experience in python for mathematical modelling, analysis tool development and data handling (numpy, scipy, pandas, git, package deployment, continuous integration)Experience with experimental test methods, sensor selection and data post-processing/ interpretationThe ability to work to deadlines within a high pressure environmentCommunication skills and the ability to build strong working relationships with colleagues and engineering professionalsDemonstrated experience with one or more industry standard thermal modelling packages: Thermal Desktop, THERMICA, NX SSTFamiliarity with manufacturing processes, including conventional machining, and additive manufacturingFamiliarity with industry standards (e.g. MIL-STD-1540, GSFC-STD-7000, ECSS-E-HB-32, NASA-STD-5001)Familiarity with Transient flow modelling/analysis.If the above sounds like you apply nowWHAT TO EXPECTWe'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.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.
