Propulsion Engineer
Confirmed live in the last 24 hours
El Segundo, CA, USA
Experience Level
Desired Skills
Data Structures & Algorithms
  • B.S. in any engineering discipline from an accredited universit
  • One or both of the following experience bases:
  • Extracurricular projects or internships/co-ops
  • 2+ years of industry experience in an integration & test, design, or production role
  • In-depth understanding of compressible/incompressible flow and thermodynamics
  • Experience with pressurized operations
  • Ability to program scripts in Python
  • Ability to use CAD design software (e.g. NX, Solidworks, CATIA)
  • Critical thinking: ABL engineers understand the “why” behind all design decisions, operational events and test outcomes
  • Ability to deal with ambiguity: ABL engineers must be comfortable defining their own pathway to an objective
  • End-to end ownership: projects are delivered fully complete and ready for flight
  • Ability to sit or stand for extended periods of time
  • Ability to use a computer to complete assignments
  • Ability to communicate with individuals and groups in person, by phone and telepresence
  • The Stage Propulsion Engineer must be willing to travel to launch and test sites to support operations and integration work
  • The team scope is broad, which means each individual's scope may be broad. We are the Stage Propulsion Responsible Engineers. You will likely end up acting in each of the capacities listed below, eventually focusing in on one of them or keeping your hands in the mix across all
  • Hardware. Own engine hardware from the moment it completes acceptance testing until it lifts off. Perform engine refurbishment, work with Production team to install onto the vehicle, travel with engine hardware to test and launch sites, and climb into the rocket to troubleshoot issues, perform checkouts, or run inspections. Write clear work instructions that keep a strong record of work performed. Learn the hardware and fluid routing like the back of your hand. Perform trades on engine and stage-level system configuration changes and be the go-to for any hardware issues that the engine is facing in its path from acceptance test to launch
  • Operations. Learn everything about engine operations and train to represent the propulsion systems on-console for stage testing and launches. Review propulsion system data and drive resolution to any issues or anomalies, generating strong documentation along the way. Question existing assumptions on how engines must be operated, develop criteria for evaluating engine health during and after testing, and automate strategically. Work with the launch team on-console to make under-pressure, informed calls on path forward during high-stakes test and flight operations. Make the final go/no-go call for RS1 engine system over comms in the countdown to RS1 launch. Your name is now “PROP” and you get to say “PROP is go for launch”
  • Analysis. Perform critical pieces of stage systems analysis, like characterizing pressurization system behavior, quantifying feed system losses, or refining our mass-sensing systems and algorithms. Always stay grounded in real data, designing and driving component, system, or stage-level testing as required. Use your results to set future block architectures or set operational bounds for the next launch op. Create documentation that clearly communicates your methodology and rationale. Work with all other vehicle systems & teams - structures, GNC, launch, ground systems, avionics - to drive mission-critical decisions

Rockets for small satellite launches
Company Overview
ABL Space Systems was founded in 2017 by veterans of SpaceX and Morgan Stanley to develop low-cost launch vehicles for the small satellite industry. More importantly, they're building a launch system they are truly proud of – no gimmicks or over-design, just reliable, rapidly deployable launches.
