Software Engineer

Description SAIC is seeking a Software Engineer to own full stack development and technical maturation of a government software prototype as it transitions from research/prototype status to a Program of Record (PoR) for our customer site in North Charleston, SC. Key Responsibilities: Serve as the full-stack engineer for a government software system, overseeing backend services, frontend applications, and supporting infrastructure. Design, develop, and maintain APIs and services using Go and Python, while driving the technical roadmap to transition a research prototype into a production-ready system for a Program of Record. Refactor, re-architect, and harden prototype code to meet security, scalability, maintainability, and supportability standards required for fielded DoD/government systems. Collaborate with cybersecurity/ISSO personnel to implement RMF-compliant technical controls, support ATO accreditation, and contribute to required security documentation/artifacts. Enforce secure software development practices, including secure coding standards, vulnerability management, container hardening, secrets management, logging/auditing, and secure CI/CD pipelines. Integrate and advocate for AI-assisted development tools to enhance code quality, security posture, and software delivery efficiency. Qualifications Required Education and Experience: Bachelors and five (5) years or more work experience; (4) four years of additional work experience accepted in lieu of degree. Demonstrated proficiency in Go, Python. Active, hands-on use of AI development tools (e.g., Claude Code, GitHub Copilot, Cursor, or similar AI coding assistants) as part of daily engineering work. Practical experience with cybersecurity-conscious software engineering — secure coding practices, vulnerability remediation, container/infrastructure hardening, or similar. Experience taking prototype/research-grade code and maturing it into a production, supportable system. Desired Qualifications: Direct experience supporting an ATO package (SSP development, control implementation, POA&M management, eMASS). Experience with containerization/orchestration (Docker, Kubernetes) and CI/CD pipeline security. Familiarity with DoD software acquisition processes and prototype-to-Program-of-Record transitions. Experience with cloud environments (AWS GovCloud or similar) in an accredited/compliance-driven context. Prior experience in a DoD, IC, or other federal contracting environment. Proficiency with React and Rust. Familiarity with the general lifecycle of moving a system through security accreditation (RMF, ATO, or equivalent commercial/compliance frameworks) — prior direct ATO experience is a strong plus but not mandatory. Required Security Clearance: Must be a US Citizen with an active Interim Secret clearance to start and the ability to obtain and maintain a secret security clearance.
