Software Architect / Space Communications Program

Peraton•Las Cruces, NM

1d•$86,000 - $138,000•Onsite

About The Position

Peraton is seeking a Senior Software Architect SME to support a highly visible program at NASA's White Sands Complex in Las Cruces, New Mexico. This role will lead the architecture review, documentation, and modernization of a large-scale legacy ground system codebase supporting NASA Space Relay network operations. The right candidate brings deep experience with legacy systems, a track record of leading technical teams through complex software recoveries and the ability to operate effectively in a structured government program environment. Peraton is the prime contractor for NASA at the White Sands Complex (WSC) near Las Cruces, New Mexico. Operating here are two functionally identical satellite ground terminals: The White Sands Ground Terminal, and the Second TDRSS Ground Terminal. These ground terminals ensure uninterrupted communications between various ground stations, NASA’s orbiting fleet of Tracking and Data Relay Satellites (TDRS), customer spacecraft (satellites), and the computer systems that support such spacecraft. WSC serves as an interface for distributing satellite data to control centers and scientists who then use the daily influx of data to expand our ever-growing knowledge of the Earth and the universe.

Experience on programs with formal configuration management, change request processes, and review gates in a government or DoD/NASA environment
Ability to develop and maintain technical documentation for legacy systems with little or no existing documentation

Nice To Haves

Demonstrated experience using AI to assist in code comprehension and documentation is a plus
Experience leading formal architecture reviews of systems the candidate did not originally build, including undocumented or minimally documented systems
Experience with NASA ground systems, space relay systems, or mission-critical ground software
Familiarity with AI-assisted code comprehension tools (e.g., AskSage or equivalent approved government AI platforms)
Experience building or directing API-driven or RAG-based code analysis workflows using Python
Experience with Oracle, MSSQL; Postgres preferred
Experience migrating legacy codebases from end-of-life platforms (hardware or OS) to modern environments
Familiarity with MBSE tools (e.g., MagicDraw/Cameo)
Experience with Confluence for technical knowledge management

Responsibilities

Develop and update technical architecture documentation for a legacy system to close knowledge gaps and support long-term sustainment
Mentor a team of software engineers through a structured modernization and platform rehost effort, especially using AI tools and methods to gain efficiency.
Define and implement software development processes, toolchain standards, and CI/CD pipelines
Drive adoption of agile methodologies including sprint planning, peer estimation, and Definition of Done enforcement
Direct AI-assisted code comprehension workflows using NASA-approved tools
Support the development of backend effort estimates grounded in architecture analysis
Coordinate with NASA task monitors and program leadership on technical progress and formal review gates
Maintain and evolve technical documentation as a living knowledge base in support of long-term program sustainment
