Jacobs ESSSA Group offers a partnership in which you can grow personally and professionally with the advantages of strong leadership, competitive compensation, and rewarding career paths. Come join the team whose work is destined to have a long-range effect on future generations!


We are searching for highly qualified candidates supporting various roles in the area of launch vehicle control system design, analysis and modeling. The selected applicant will work independently and in a customer/contractor integrated, collaborative team to:

  • Conduct analysis for the design, development, and definition of the flight control systems for launch vehicles and spacecraft.
  • Develop, implement, and maintain simulation models of vehicle dynamics (rigid body, flexible structure, Thrust Vector Control actuator and slosh), environments, and GN&C components.
  • Analyze stability and robustness of the flight control system in time and frequency domains.
  • Use mathematical modeling and computer simulations to analyze ascent, on-orbit, and reentry flight dynamics.

A degree in Aerospace, Mechanical or Electrical Engineering or related field from an ABET accredited institution is required. Typically, educational requirements are the equivalent of a Ph.D. with a minimum of 4 years of experience, a Masters with at least 6 years of experience, or a BS with at least 10 years of experience.

Skills and experience should demonstrate:

  • Extensive experience applying modern and classical control system design methods to complex systems.
  • Strong understanding of 6DOF simulation, guidance, navigation, and control functions for aerospace vehicles.
  • Experience implementing and validating detailed mathematical models of aerospace systems/subsystems.
  • Experience with orbital mechanics, ascent flight mechanics, and navigation systems is desired.
  • Proficiency in MATLAB, Simulink, C and C++.
