  • Implementation, unit testing, and integration
  • Deployment and sustainment in operational environments
• Collaborate with systems engineering, mission operations, and other ground software teams to integrate mission planning capabilities with the broader ground segment.
• Implement and maintain automation, pipelines, and tools (e.g., Python‑based workflows, CI/CD jobs) to support mission analysis and operations.
• Contribute to technical documentation, design artifacts, and customer briefings for mission planning solutions.

Mission Planning & Astrodynamics Responsibilities

• Lead and/or support the design and implementation of software capabilities for:
  • Orbit determination and ephemeris propagation
  • Maneuver planning and station‑keeping strategy
  • Conjunction assessment and collision avoidance

  • Launch and early orbit operations (LEOP), station keeping, on‑orbit support, and anomaly response
• Work closely with astrodynamics, flight dynamics, and operations teams to turn mission concepts and operational needs into robust, repeatable software solutions.
• Integrate and operationalize COTS astrodynamics tools, including:
  • FreeFlyer
  • STK
  • Scripts and interfaces that connect these tools to other ground systems and data sources
• Support Rendezvous and Proximity Operations (RPO) analysis and planning, as applicable to mission needs.
• Help shape the technical roadmap for mission planning tools and services, including performance, automation, and operational usability improvements.

 

Basic Qualifications

• Bachelor’s degree in a Science, Technology, Engineering or Mathematics (STEM) discipline and 12+ years of relevant software/mission experience; OR
  Master’s degree in STEM and 10+ years of relevant experience; OR
  PhD in STEM and 8+ years of relevant experience.
• Strong background in software development for complex systems, with emphasis on:
  • Python (preferred primary language for this role)
  • Experience with at least one additional language (e.g., C/C++, Java) is a plus.
• Familiarity with all phases of the software development life cycle and Agile software development practices.
• Experience with:
  • Linux development environments and scripting (e.g., Bash)
  • Containerization (e.g., Docker, Podman) and CI/CD tools (e.g., Jenkins, GitLab, Bitbucket/Jira, Git, etc.)
  • Configuration management using industry‑standard tools and processes
• Demonstrated experience supporting at least one of the following:
  • Astrodynamics / orbital mechanics / flight dynamics
  • Mission planning and satellite operations
• Hands‑on experience performing some combination of:
  • Orbit determination
  • Maneuver planning and station‑keeping
  • Conjunction assessment / collision avoidance
  • Ephemeris propagation and trajectory analysis
  • Contact/passes planning and satellite mission analysis
• Ability to work onsite full‑time in McLean, VA in a secure environment.

Clearance:

• Active DoD Top Secret clearance is preferred at time of application; candidates with the ability to obtain and maintain a TS and any required special program access will also be considered.

 

Preferred Qualifications

• Active TS/SCI clearance with current or recent program access.
• Degree in Aerospace Engineering or Physics with significant coursework or experience in astrodynamics and space mission operations.
• Direct experience using FreeFlyer and/or STK for mission analysis, mission planning, and/or on‑orbit operations, including integration or automation.
• Experience supporting:
  • Launch and early orbit operations (LEOP)
  • Station keeping and collision avoidance
  • Rendezvous and proximity operations (RPO)
  • Long‑term mission planning and on‑orbit anomaly resolution
• Experience with:
  • Model‑based systems engineering tools (e.g., Rhapsody, Cameo)
