Senior Ground Enterprise Systems Engineer

Arcfield•Chantilly, VA

About The Position

Arcfield is seeking a Senior Platform Integration & Architecture Manager to support the Merigold program, providing senior SETA systems engineering and technical integration support for enterprise software development platforms within the Ground Enterprise Directorate. This role serves as a senior technical integrator across development environments operating at multiple security levels, helping the Government architect, modernize, automate, and sustain secure, interoperable platform capabilities that enable software development and delivery across the enterprise. You will provide technical leadership across platform architecture, DevSecOps toolchains, CI/CD pipelines, infrastructure and configuration automation, artifact and source-code management, software dependencies, FOSS and OEM lifecycle management, cybersecurity, and secure multi-domain development environments. You will work across Government organizations, platform teams, developers, cybersecurity professionals, infrastructure providers, and mission partners to identify dependencies and ensure individual platform decisions support a cohesive enterprise development ecosystem. The ideal candidate combines deep technical architecture expertise with systems engineering leadership. You understand how development platforms actually operate - from infrastructure and software dependencies through security boundaries, patching, data movement, and developer workflows - and can translate that understanding into sound enterprise architecture and Government decision-making.
