Thermofluids Engineer II

ABOUT ROCKET LAB

Rocket Lab is an end-to-end space company delivering responsive launch services complete spacecraft design and manufacturing payloads satellite components and more all with the goal of opening access space. 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 rockethas become the second most frequently launched U.S. rocket annually and has delivered more than 230 satellites to orbit all while we work to develop Neutron our upcoming medium-lift reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds our extensive line of satellites payloads and their components including spacecraft that have been selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope.

NEUTRON
Rocket Labs Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life. From designing and testing Neutrons structures and components to firing up its new Archimedes engines to setting up Neutrons 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.

THERMOFLUIDS ANALYST
Rocket Labs integrated analysis team contributes to the operation and development of Neutron by using modelling and simulation to solve challenging problems involving dynamics fluid flow and thermodynamics. You will develop and be the technical owner of launch vehicle and payload thermal environments heat transfer correlations and post-flight data review and validation.
As a Thermofluids Analyst in Rocket Labs Analysis team you will contribute to the analysis design validation and improvements of Rocket Labs launch vehicles. Day to day you will be expected apply first principles to define vehicle thermal environments (in-transport on-pad flight recovery); guide vehicle thermal architecture definition; correlate thermal models with test stack and flight data; assess customer payloads to ensure thermals stay within operating limits.
Join a driven team thats tackling challenging projects delivering on exciting missions and making an impact on the future of space!

WHAT YOULL GET TO DO:
-Perform heat transfer analysis (conduction convection and radiation) including:
-Heat transfer coefficient correlations (internal and external)
-1D thermal analysis
-Creation of thermal resistance networks
-Integrated thermal analyses for customer payloads
-Define in-space and vehicle thermal environments
-Conduct thermal analyses of propellant gas and tank interactions
-Work closely with design and test engineers to iterate through design concepts determine test requirements and demonstrate positive margins
-Support process and interpret ground test and flight data

YOULL BRING THESE QUALIFICATIONS:
-A degree in Mechanical Aerospace Engineering or similar field
-2 years industry experience ideally from the Aerospace Automotive Nuclear HVAC industries
-Strong understanding of physical principles (heat transfer electronics internal flow aerodynamics etc.)
-Experience with one or more industry standard thermal modelling packages: Thermal Desktop THERMICA NX SST
-Thermal protection system design specification and implementation.
-Knowledge of HVAC system design and/or analysis.
-Demonstrated thermal modelling of components networks and lump masses
-Experience withexperimental test methodssensor selection and data post-processing/ interpretation(thermocouples pressure transducers accelerometers strain gauges microphones etc.)

THESE QUALIFICATIONS/SKILLS WOULD BE NICE TO HAVE:
-Knowledge around space thermal environments and modelling for both orbital and ascent environments.
-Demonstrated experience with one or more industry standard CFD packages: Fluent CFX STAR-CCM
-Fluid engineering experience around pressure loss valves and sensors
-Experience in Python and associated scientific packages: numpy pandas scipy matplotlib
-Experience with dynamic thermofluid systems
-Compressible gas modelling of pressure vessels pressurisation systems and piping
-Familiarity using Solidworks CAD and PDM packages (or comparable industry standard packages) with emphasis on model interrogation and defeaturing for subsequent analyses
-Familiarity with industry standards (e.g. MIL-STD-1540 GSFC-STD-7000 ECSS-E-HB-32 NASA-STD-5001)

WHAT TO EXPECT

Were on a mission to unlock the potential of space to improve life on Earth but thats 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 others 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.
