About the role

The Aerospace Corporation is the trusted partner to the nation’s space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space— delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you’ll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space.

The Defense Systems Group (DSG) provides analysis-based decision support to senior leaders on space architecture, policy and strategy, technology development, warfighter capability enablers, systems integration, defense industrial base, and threat reduction to help shape existing and future space missions across the national security space (NSS) enterprise. DSG is unique at Aerospace as it not only directly supports major customers, including the U.S. Space Force, U.S. Space Command, Air Force Materiel Command, and senior leadership at the Pentagon, but also provides a broad range of technical support across the national space enterprise, maintaining vertical responsibilities with customers’ portfolios as well as horizontal, matrixed responsibilities across the corporation. Additionally, DSG provides deep technical expertise to the Space Force Space Systems Command (SSC) in the conception, design, acquisition, launch and operations of satellite, launch vehicle, ground control, and range systems.

Join a team of technical analysts in the International Launch Systems office as a Software Systems Engineer to support missile warning, missile defense and other programs. As part of the team, you will identify and solve hard software problems in tools that impact current and future customer missions. You will work closely with technical analysts to understand customer needs and work independently to develop software solutions.

The selected candidate will be required to work part-time (up to an average of 20 hours per week), on-site at our facility in El Segundo, California.  This is a part-time casual position with limited hours.

  • Work with in-house technical engineers to maintain and develop critical software.
  • Solve complex and nuanced Fortran issues.
  • Work with outside organizations to debug issues in their products.
  • Provide a modern software baseline for the next generation of technical analysts.

What You Need to be Successful:

  • Bachelor’s degree in software engineering or related field.
  • 8 or more years of experience in software engineering or related field.
  • Deep understanding of Fortran and available Fortran compilers.

  • This position requires ability to obtain and maintain a security clearance, which is issued by the U.S. government. U.S. citizenship is required to obtain a security clearance.

How You Can Stand Out

  • Advanced degree in software engineering [applicable STEM areas or other discipline]
  • 10 years of recent experience developing and/or maintaining Fortran software.
