Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.\nPROPULSION ENGINEER (RAPTOR TEST)\nThe propulsion engineer is responsible for ensuring Raptor engines and components have been tested and qualified to function in flight conditions. Our engineers specialize in the design and execution of unique development tests for Raptor engine testing on an accelerated schedule. This role offers a constant variety of diverse engineering challenges in a fast-paced, hands-on environment. Raptor Test Engineers have the opportunity to work on one of the world’s most complex engines to date, a full flow staged combustion engine! Join the team and our journey to Mars and we solve new challenges presented by unknown frontiers.\nRESPONSIBILITIES:\nDevelop and execute tests at the engine and component level to evaluate hardware performance and survivability during the mission.\nRepeated ownership of test campaigns; including test plan creation, new system activation, test operations, data review, and test stand equipment design/fabrication.\nProvide daily direction and instruction to technicians to fabricate and integrate test articles and stand equipment.\nDevelop and maintain test procedures, sequences, scripts, configuration files, and software.\nOperate and troubleshoot data acquisition and control systems, wiring, and instrumentation. DAQ systems are primarily National Instruments based.\nOperate and troubleshoot fluid and mechanical systems that include low to high-pressure gaseous working fluids and rocket propellants (including high pressure nitrogen and methane systems & cryogenics) as well as structural components and supporting infrastructure.\nOperate mechanical systems; these include test stand support structures, heat exchangers, vacuum pumps, tooling, and fluid components such as valves, reliefs, burst disks, tubing, etc.\nAutomate repetitive test operations to increase efficiency and safety.\nDevelop innovative processes to increase testing capability and rates, while maintaining high rigor of safety.\nIdentify and characterize system pitfalls and potential hazards then work to resolve such anomalies by collaborating with design engineers on improvements for test stands and flight hardware.\nOperate test console and direct a team of technicians to execute test processes.\nAnalyze and review data to ensure that hardware is operating as expected utilizing numerical data analysis tools to interpret test results.\nDevelop, maintain, and execute integration and testing process, and collaborate with design engineers to improve hardware.\nAct as a conduit for completing the resource management process, including: planning, parts, coordination, skilled labor coordination, process verification, etc.\nBASIC QUALIFICATIONS:\nBachelor’s degree in an engineering discipline or physics \n1+ years of hands-on testing experience (experience from internships, clubs or other hands-on extra-curricular activities qualifies)\n PREFERRED SKILLS AND EXPERIENCE:\nMaster’s degree in Mechanical or Aerospace Engineering or equivalent experience\nExperience in production and test systems\nHands on test and production facility, factory, or laboratory experience\nMechanical aptitude and experience\nDemonstrated experience where quick-thinking and problem solving plays a critical role\nKnowledge and/or experience in aerospace structural or mechanical or propulsion systems assembly and testing\nAbility to utilize test instrumentation and control components: pressure transducers, thermocouples, RTDs, strain gauges, accelerometers, flow meters, load cells, relays, solenoid valves\nAbility to solve problems calling for technical analysis\nAbility to read and understand technical manuals and reports\nAbility to read and understand mechanical and electrical schematics\nKnowledge of hazardous systems- cryogenic, flammable, hypergolic, pyrophoric\nKnowledge of high pressure system design and handling\nExperience using test instrumentation and control components\nWindows Operating Systems, Intermediate skill level\nMicrosoft Office (Excel, PowerPoint, Word, Outlook, OneNote), Intermediate skill level\nCAD modeling (Unigraphics NX preferred) and Teamcenter, Novice skill level\nProgramming Languages (Python, C/C++, SQL), Novice-Intermediate skill level\nADDITIONAL REQUIREMENTS:\nFlight hardware is typically built in tight quarters and physical dexterity is required\nPhysical effort including sitting or standing for extended periods of time, lifting and carrying weight such as materials or equipment (up to 25 lbs. unassisted)\nWork performed in an environment with exposure to fumes, odors and noise\nOccasionally exposed to work in extreme outdoor environments (heat, cold, rain)\nHours vary depending on site operational needs; flexibility required\nITAR REQUIREMENTS:\nTo conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
