Software Engineer - TS​/SCI

Description

ARS is seeking an experienced Software Developer to support a classified secure cloud platform delivery effort for a U.S. Navy customer. This role is focused on developing platform-integrated tooling, automation, and user-facing capabilities across multiple classification tiers, enabling mission teams to onboard and operate effectively within Government-furnished cloud enclaves. This is a hands‑on development role requiring demonstrated experience in classified environments, the ability to operate independently from day one, and the discipline to produce thorough documentation in support of formal platform delivery.

An active TS/SCI clearance is required at time of hire.

• Design, develop, and maintain software components that integrate with and extend the secure cloud platform across IL5, IL6, and TS enclave tiers.
• Build automation tooling and scripted workflows supporting dynamic user provisioning, environment configuration, and platform onboarding.
• Develop and maintain APIs, interfaces, or internal portal capabilities that enable mission teams to interact with platform services.
• Implement software solutions in alignment with enclave‑specific security requirements, approved software baselines, and applicable STIGs.
• Ensure all developed code is tested, documented, and delivered in accordance with classified environment standards and Government approval processes.
• Collaborate with Dev Ops and ISSE personnel to ensure software integrations are architecturally sound and security‑compliant across all enclave boundaries.

• Produce engineering‑quality development documentation including design specifications, integration guides, and delivery artifacts required for platform acceptance.
• Support formal delivery processes including configuration‑controlled code submissions and handoff documentation across classification tiers.
• Coordinate with Dev Ops and ISSE team members on issue resolution, integration testing support, and cross‑discipline knowledge transfer.
• Other duties as assigned.

• US citizenship required.
• Active Top Secret clearance with SCI eligibility is required at time of hire; interim clearances are not accepted.
• Active Security+ certification (DoD 8140 compliant).
• 5+ years of demonstrated hands‑on software development experience in classified or similarly restrictive environments.
• Proficiency in one or more languages relevant to classified cloud platform environments, including Golang, Python, Bash, Power Shell, and/or JavaScript/Node.
• Experience developing automation, scripting, or tooling in support of infrastructure or platform delivery (not solely application development).
• Familiarity with containerization and orchestration technologies (Docker, Kubernetes, Podman, etc.) particularly in restricted or air‑gapped environments.
• Experience working with relational databases (e.g. Postgre
  
  SQL) in disconnected or controlled environments, including schema design, query optimization, and secure data handling.
• Familiarity with Salt/Salt Stack or equivalent configuration management frameworks is strongly preferred.
• Direct experience working in classified or air‑gapped environments (SCIF access, air‑gapped networks, offline tooling).
• Ability to produce clear, structured technical documentation suitable for classified delivery and Government review.
• Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related field OR equivalent experience demonstrating the required technical competencies.

All positions at Applied Research Solutions are subject to background investigations. Employment is contingent upon successful completion of a background investigation including criminal history and identity check.
