Job Summary

The Astrodynamics Team is responsible for conducting a range of modeling, simulation, and analyses in areas such as space mission design, trajectory design, orbital maneuvers, orbit estimation, space debris collision and avoidance analyses, and space domain awareness. Engineers in the Astrodynamics group are integral throughout the entire program lifecycle. They are key contributors in the bid & proposal phase, providing inputs to overall constellation and mission design. They are directly responsible for determining the necessary capability of the satellite’s propulsion system. They oversee the orbital Concept-of-Operations (CONOP), designing trajectory and maneuvering profiles to meet key mission objectives. They follow programs from inception to on-orbit operations and through end-of-life disposal.

As an Astrodynamics Engineer, you will be the Responsible Engineering Authority (REA) for the Astrodynamics subsystem for a given program, study, or proposal. In addition to execution of technical design, analysis, and operation, you may be responsible for project management activities to support programs, ensuring that high-quality work products are delivered on-time.

In addition to your engineering responsibilities, as an experienced member of the team you will be expected to set the engineering standard for the Astro team. You will define methods, tools, and processes to follow, and you will be accountable for the quality of the work coming from the group at large. You will be expected to mentor other members of the team, and develop the next generation of Astrodynamics engineering talent.

This position's internal job code is Guidance, Nav & Controls Engr. Our team is currently hiring for levels 4 - 6 .
