2+ years of experience in DevSecOps, DevOps, or Software Engineering with a heavy focus on infrastructure and pipeline automation.
Strong experience building and managing CI/CD pipelines (e.g., GitLab CI, Jenkins, or similar).
Proficiency in Linux-based environments, including advanced shell scripting, system administration, and performance tuning.
Experience with containerization technologies (e.g., Docker, Podman) and orchestration tools.
Strong experience with Python or other scripting languages for automation task development.
Familiarity with building and packaging compiled languages, specifically modern C++ applications.
Strong problem-solving skills and the ability to work effectively in a collaborative, cross-functional team environment.
US Citizenship is required and ability to obtain and maintain and DoD Secret clearance.

Nice To Haves

Experience implementing automated security testing (e.g., SonarQube, Fortify, Nexus/Artifactory scanning tools).
Exposure to radar, RF, or sensor systems and deploying software to hardware-in-the-loop (HWIL) environments.
Experience with Infrastructure as Code (IaC) tools like Ansible, Terraform, or equivalent.
Familiarity with distributed applications or messaging frameworks (e.g., ZeroMQ).
Experience supporting web applications built with Angular TS, Flask, and SQL-based databases.
Knowledge of military cybersecurity standards or framework hardening (e.g., NIST SP 800-53, Risk Management Framework / RMF).

Responsibilities

Design, implement, and maintain secure CI/CD pipelines to automate the build, test, and deployment environments for modern C++ applications.
Integrate and manage automated security tools (e.g., SAST, DAST, dependency scanning, and container vulnerability scanning) into the development lifecycle.
Automate infrastructure provisioning and configuration management using Infrastructure as Code (IaC) principles.
Collaborate closely with software, systems, and hardware engineers to optimize software compilation times, build scalability, and deployment reliability.
Support software integration and deployment in operational, simulated, and hardware-in-the-loop (HWIL) testing environments.
Enforce cybersecurity compliance and hardening guidelines (such as DISA STIGs) across Linux-based development and runtime environments.
Troubleshoot and resolve build failures, environment disparities, and pipeline bottlenecks to ensure high developer velocity.
