About the Job

Requirements

  • At least 9 years of experience without a degree, or 7 years with an Associate of Arts or Associate of Science degree, or 5 years with a Bachelor of Arts or Bachelor of Science degree, or 3 years with a Master of Arts or Master of Science degree, or 1 year with a Ph.D.
  • An active Top Secret/Sensitive Compartmented Information clearance with an adjudicated polygraph.

Responsibilities

  • Support the subject matter expert in test planning, system validation, integration testing, and operational verification of flight safety software tools used in 24/7 operations.
  • Support integration and verification testing of new data sources and software capabilities within legacy and next-generation flight safety systems.
  • Design, execute, and document software test plans, regression tests, and operational validation scenarios in test and pre-production environments.
  • Use Bash and Python scripts to support automated testing, data validation, troubleshooting, and system analysis in Linux-based classified environments.
  • Validate system performance by executing conjunction assessment and screening workflows, including resident space object-to-resident space object and resident space object-to-ground proximity analysis, such as SuperCombo-type runs.
  • Perform pre- and post-launch validation of two-line element sets, state vectors, and maneuver ephemeris data against cataloged resident space objects to ensure collision-risk mitigation logic functions correctly.
  • Operate and validate orbit propagation and analysis tools, such as STK or ASW-type systems, ensuring correct input handling, output accuracy, and reporting consistency.
  • Identify defects, conduct root cause analysis, and track software anomalies discovered during testing and operational use.
  • Participate in test readiness reviews, flight safety meetings, and operational training and exercise events.
  • Develop and maintain test documentation, validation reports, and user and training materials, and provide hands-on instruction to team members.
  • Collaborate with engineers, operators, and external stakeholders to ensure system changes meet operational requirements and safety thresholds.
  • Support mission protection activities by ensuring systems accurately process resident space object catalogs, ephemeris data, and trajectory inputs to identify collision risks and support decision-making for space operations stakeholders.
  • Contribute to improving testing methodologies, system workflows, and operational procedures by identifying software issues, validating fixes in controlled environments, and supporting training-material updates based on system changes and test outcomes.

Desired Qualifications

  • At least 1 year of experience with flight safety or astrodynamics test tools, such as STK or ASW SuperCombo, or STK Level 2 certification.
  • At least 2 years of combined experience in space operations, conjunction assessment, or flight safety systems testing.
  • Understanding of orbital mechanics, conjunction analysis methods, and space domain awareness concepts.
  • Experience validating or testing systems involving resident space object catalogs, ephemeris data, and orbital propagation models.
  • Ability to write and interpret Bash and Python scripts for test automation and data analysis.
  • Familiarity with national security space mission environments, such as NRO-related systems and workflows.

About the Company

Peraton

Runs and secures technology for federal agencies

Peraton builds and runs secure technology for American defense, intelligence, space, and civilian agencies, from military networks to satellite ground stations. In 2025, the Federal Aviation Administration chose it to manage the overhaul of the nation's air traffic control system, replacing copper wiring with fiber and upgrading radar and radios. Its engineers, many holding security clearances, run and defend agency networks and data centers, write mission software, and operate space and communications systems, and agencies pay for this work through multiyear contracts. Peraton was formed in 2017, when private-equity firm Veritas Capital bought Harris Corporation's government IT business, and is based in Reston, Virginia.
