Trajectory Analyst

Company Details

We build rockets to launch small satellites.

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, we’re building a launch system we are truly proud of – no gimmicks or over-design, just reliable, rapidly deployable launches. We’re an ambitious team with big goals and, together, we’re determined to prove that reaching space can be simple, efficient, and routine.

When launch day arrives, we want you by our side

ABL’s Trajectory Analysts are responsible for performing mission design from initial concept to launch. You will drive the development of modular trajectory optimization, evaluate mission feasibility, determine vehicle performance to a range of orbits and missions. Furthermore, your work directly supports vehicle-level design decisions, launch vehicle performance analysis, as well as the development of GNC algorithms.
As a Trajectory Analyst, we hope you will enjoy solving cross-disciplinary problems, can work effectively in a fast-paced environment, and share our passion for building scalable, effective, and elegant analysis tools. This is a role that contributes to every mission and every flight we fly as continue to reimagine the future of space launches.
