THESE QUALIFICATIONS WOULD BE NICE TO HAVE: * Master's or a PhD. * Advanced proficiency in NX, ANSYS Mechanical, StarCCM, MATLAB and GD&T. * Proficiency in niche software like: TDK, ROCCID, PERCORP, CEA, ROCETS. * Reacting flow CFD. * Expertise in high-speed data/video analysis in time and frequency domains. * Experience with designing reusable, propulsively landing rocket engines. * Experience in an iterative and scrappy development environment. ## Description Based out of Rocket Lab's headquarters in Long Beach, CA, the Principal Combustion Devices Engineer will be responsible for the development of one or more combustion devices (preburners, main injectors, thrust chambers assemblies and vacuum nozzles). These devices are an integral portion of the 200,000 lbf Archimedes engine, which operates in a demanding but efficient ox-rich, staged combustion architecture. In this role, you'll take ownership of all aspects of a component: design and analysis, manufacturing and test support, and successful flights and subsequent, high-cadence, re-flights. By doing so, you will help propel the Neutron rocket, expanding human capabilities in space and providing value to the company and its shareholders. WHAT YOU'LL GET TO DO: * Design, analyze, and perform trades studies to achieve programmatic targets. * Define requirements, test and flight qualification plans. * Work with the interface owners, like turbomachinery and engine systems teams, to make a high-end product that could be iterated fast and seamlessly. * Work with manufacturing and build engineers to design easily manufacturable, cost-effective, beautiful parts. * Work with the test and launch teams to interpret data and provide solutions to enable a high cadence - of tests, flights and re-flights.
