We are seeking a Full-Stack Developer / DevSecOps Engineer Senior to join our team in delivering secure, scalable, cloud-native applications that support critical national toolsets and large-scale user bases. This role combines hands-on software engineering with DevSecOps principles to embed security, automation, and resilience throughout the development lifecycle. The ideal candidate thrives in a collaborative, Agile / Scrum environment, bringing expertise in modern full-stack development, containerized microservices, GitOps-driven CI / CD, and secure-by-design practices. You will contribute to building and sustaining high-performance systems in classified environments, leveraging tools aligned with the Enterprise DevSecOps Reference Design (including CNCF Kubernetes, hardened containers from Iron Bank, and zero-trust architectures).

Whether your strength lies in crafting clean, testable code across frontend and backend, optimizing deployment pipelines, or integrating security controls (shift-left security, vulnerability scanning, SBOMs), you will drive innovation while ensuring compliance with rigorous standards (, RMF, continuous ATO reciprocity, STIGs). Candidates must excel at independent problem-solving, critical thinking, and clear communication-both oral and written-while collaborating across development, security, operations, and mission stakeholder teams.

Responsibilities

Design, develop, maintain, and enhance full-stack web applications and microservices to support national-scale toolsets with high availability and large user bases.

Implement and manage secure CI / CD pipelines, infrastructure as code (IaC), and automated deployments in cloud-native Kubernetes environments.

Deploy and harden new systems, networks, and containerized workloads with embedded security practices.

Conduct data processing, post-processing, reduction, and analysis to support mission outcomes.

Apply Scrum / Agile framework principles in daily work, including sprint planning, backlog refinement, ceremonies, and continuous improvement.

Produce well-documented analysis reports, technical briefings, and artifacts for stakeholders.

Troubleshoot defects, collaborate closely with users / end-users to resolve issues, and deploy timely, secure fixes.

Contribute to all phases of the software development lifecycle in a highly collaborative, cross-functional Scrum team.

Assist senior engineers with complex assignments while mentoring juniors on best practices.

Ensure code is efficient, testable, maintainable, and adheres to secure coding standards (, OWASP, hardening guidelines).

Basic Hiring Criteria

Bachelor's degree in Engineering, Computer Science, Information Technology, or related field.-Minimum 10 years of professional experience in software development, DevSecOps, or related engineering roles.-

Active Top Secret security clearance with SCI access (TS / SCI).-

Desired Qualifications

Strong backend development experience with languages such as Golang (preferred for cloud-native / DevSecOps tools), , C++, Python, or similar.

Proficiency in frontend technologies : React, TypeScript, JavaScript for building responsive, user-facing web applications.

Expertise in CI / CD tools (, GitLab CI, Jenkins, Argo CD for GitOps, Argo Workflows for complex pipelines).

Hands-on experience with containerization and orchestration : Docker, Kubernetes (CKA / CKAD certification a plus), including deployment, scaling, and management in DoD environments.

Knowledge of cloud security and multi-cloud platforms (AWS GovCloud, Azure DoD IL, GCP), including zero-trust models and compliance.

Container and runtime security practices (, vulnerability scanning, policy enforcement with Kyverno / OPA, hardened images from Iron Bank).

Scripting and automation : Python, Bash, IaC tools (Terraform, Ansible).

Database experience : SQL (PostgreSQL, MySQL) and NoSQL (MongoDB); familiarity with observability backends (, Prometheus, Loki).

API design and implementation : RESTful APIs, GraphQL, gRPC, where applicable.

Version control and collaboration : Git (GitLab / Repo One preferred).

Observability tools : Grafana (dashboards / visualization), Jaeger or Tempo (distributed tracing), Prometheus (metrics), EFK / PLG stacks (logging).

Solid Linux experience (system administration, troubleshooting, container hosts).

Deep understanding of microservices architecture, service meshes (, Istio for zero-trust / mTLS), and modular, loosely coupled designs.

Proven ability to produce clean, efficient, testable code that meets technical and secure coding requirements.

Experience working in Agile / Scrum teams, contributing end-to-end from requirements to deployment in high-stakes, classified settings.

Fundamental knowledge of operating systems, networking, and programming paradigms to support platform-level troubleshooting and innovation.

Benefits offered to vary by the contract. Depending on your temporary assignment, benefits may include direct deposit, free career counseling services, 401(k), select paid holidays, short-term disability insurance, skills training, employee referral bonus, affordable medical coverage plan, and DailyPay (in some locations).
