Job description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

PROPULSION ENGINEER (RAPTOR TEST)

The 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.

RESPONSIBILITIES:

• Develop and execute tests at the engine and component level to evaluate hardware performance and survivability during the mission.
• Repeated ownership of test campaigns; including test plan creation, new system activation, test operations, data review, and test stand equipment design/fabrication.
• Provide daily direction and instruction to technicians to fabricate and integrate test articles and stand equipment.
• Develop and maintain test procedures, sequences, scripts, configuration files, and software.
• Operate and troubleshoot data acquisition and control systems, wiring, and instrumentation. DAQ systems are primarily National Instruments based.
• Operate 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.
• Operate mechanical systems; these include test stand support structures, heat exchangers, vacuum pumps, tooling, and fluid components such as valves, reliefs, burst disks, tubing, etc.
• Automate repetitive test operations to increase efficiency and safety.
• Develop innovative processes to increase testing capability and rates, while maintaining high rigor of safety.
• Identify 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.
• Operate test console and direct a team of technicians to execute test processes.
• Analyze and review data to ensure that hardware is operating as expected utilizing numerical data analysis tools to interpret test results.
• Develop, maintain, and execute integration and testing process, and collaborate with design engineers to improve hardware.
• Act as a conduit for completing the resource management process, including: planning, parts, coordination, skilled labor coordination, process verification, etc.

BASIC QUALIFICATIONS:

• Bachelor's degree in an engineering discipline
• 1+ years of hands-on testing experience (experience from internships, clubs or other hands-on extra-curricular activities qualifies)

PREFERRED SKILLS AND EXPERIENCE:

• Master's degree in Mechanical or Aerospace Engineering or equivalent experience
• Experience in production and test systems
• Hands on test and production facility, factory, or laboratory experience
• Mechanical aptitude and experience
• Demonstrated experience where quick-thinking and problem solving plays a critical role
• Knowledge and/or experience in aerospace structural or mechanical or propulsion systems assembly and testing
• Ability to utilize test instrumentation and control components: pressure transducers, thermocouples, RTDs, strain gauges, accelerometers, flow meters, load cells, relays, solenoid valves
• Ability to solve problems calling for technical analysis
• Ability to read and understand technical manuals and reports
• Ability to read and understand mechanical and electrical schematics
• Knowledge of hazardous systems- cryogenic, flammable, hypergolic, pyrophoric
• Knowledge of high pressure system design and handling
• Experience using test instrumentation and control components
