About the Role

We are looking for a senior software engineer who can operate comfortably across software development, cloud infrastructure, and security compliance and take ownership of it. This is a hybrid position where you will drive both technical delivery and NIST Risk Management Framework (RMF) / Authority to Operation (ATO) execution for a cloud-based application. You’ll work directly with engineers and clients, ensuring the system is built correctly, secure, compliant, and ready for authorization.

Responsibilities

• Lead the RMF/ATO lifecycle, including documentation, control implementation, and audit readiness.
• Design and guide development and enhancement of a secure, cloud‑native application.
• Work closely with engineers to ensure security is built into the development process, not added later.
• Support and mentor junior engineers, helping them grow into hybrid roles.
• Collaborate directly with clients and stakeholders to navigate compliance requirements.
• Oversee deployments in cloud environments using Docker, Docker Swarm, and Kubernetes.
• Help integrate security into CI/CD pipelines and DevSecOps practices.

Qualifications

• 7+ years of experience in software engineering, cybersecurity, or a related field.
• Demonstrated experience with RMF/ATO execution (not just exposure).
• Strong understanding of NIST frameworks (e.g., 800‑53).
• Experience building applications using Node.js, TypeScript, JavaScript, C#, or modern front‑end frameworks such as Vue.js.
• Experience working in AWS and/or Azure environments.
• Solid understanding of databases such as PostgreSQL, MongoDB, and Redis.
• Hands‑on experience with Docker and containerized deployments.
• Ability to communicate effectively with both technical teams and clients.

Preferred Qualifications

• Experience working in federal, DoD, or regulated environments.
• Background in leading RMF/ATO efforts or accreditation strategy.
• Experience with microservices architectures.
• Familiarity with DevSecOps tooling and automated compliance.

Clearance

Able to obtain a security clearance.
