Job summary

Insight Global seeks a visionary Principal DevSecOps Engineer to architect, secure, and scale mission-critical software delivery platforms across airborne, maritime, and ground environments.

You will lead security strategy, mentor teams, and ensure resilient, rapid deployments with cloud, container security, SBOM, SAST/DAST, and governance.

Qualifications

• Education: B.S. or higher in an engineering field (Computer, Software, Math, Physics, Electrical, or related technical discipline).
• Experience: 10+ years of progressive experience in DevSecOps or software engineering, with at least 2+ years in a dedicated technical leadership or architectural role focused on DevSecOps.
• Strong proficiency in a strongly typed language (preferably C++) for developing, reviewing, and auditing complex software systems, complemented by extensive scripting capabilities in Python and Bash.
• Proven track record of architecting and managing production-grade container orchestration platforms (Kubernetes) in disconnected/degraded/decentralized environments.
• Deep expert-level knowledge of Linux operating systems (RHEL, Ubuntu) and low-level Linux networking, network architecture, and advanced troubleshooting.
• Deep familiarity with building software systems subject to national security requirements, including hands-on experience with STIG compliance, continuous monitoring, and security auditing tools.
• Extensive experience driving technical execution within Agile/Scrum development methodologies.
• Experience implementing metrics, logs, tracing and other telemetry across complex microservices to rapidly isolate failure modes in both on-prem and cloud environments.

Responsibilities

• Technical Leadership & Strategy: Define the vision for DevSecOps, cloud architecture (AWS, Azure, govcloud), automated delivery pipelines, and Fuse's platform operating systems and utilities.
• Security Architecture & Hardening: Lead the architectural design for automated container hardening, policy-driven operating system security (e.g., SELinux), SBOM generation and management, and continuous monitoring.
• Enterprise CI/CD & Orchestration: Architect, scale, and optimize enterprise-grade CI/CD frameworks utilizing GitLab CI, Ansible, Podman/Docker, Kubernetes, and RPM package management systems.
• Governance & Process Enforcement: Establish, maintain, and enforce rigorous Software Development Processes and secure coding governance frameworks across all concurrent engineering projects.
• Security Integration: Direct the integration and automation of advanced Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), Software Composition Analysis (SCA), and code metrics tooling.
• Cross-Functional Collaboration: Partner closely with Project Management, Systems Engineering, Cybersecurity, and executive leadership to align infrastructure and product capabilities with sprint schedules and mission-critical release targets.
• Infrastructure Management: Oversee the architecture and resilience of on-premises infrastructure (Jira, GitLab, vCenter/vSphere/ESXi environments, GNS3, etc) and the development networks.
• Innovation & AI Adaptation: Evaluate and introduce emerging pipeline methodologies, including the strategic integration of AI tools within CI/CD pipelines to optimize efficiency and software quality.
• Mentorship: Act as a technical mentor all engineering levels, fostering a culture of high performance, security mindfulness, and continuous learning.
