Senior Full-Stack Software Engineer (Infrastructure/DevOps)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Full-Stack Software Engineer (Infrastructure/DevOps) based in the United States.

As a Senior Full-Stack Software Engineer (Infrastructure/DevOps), you will play a critical role in modernizing large-scale technology systems that support important national missions. You will design and operate secure, cloud-native infrastructure while helping engineering teams accelerate delivery through advanced automation and DevOps practices. This role combines infrastructure engineering, software development, security, and AI-assisted workflows to build reliable and compliant platforms. You will work on mission-critical modernization initiatives, replacing legacy systems with scalable web-based solutions. The position is ideal for an experienced engineer who enjoys solving complex technical challenges, improving developer experiences, and building secure environments in highly regulated settings.

• Design, build, and maintain secure cloud infrastructure using Infrastructure as Code practices, primarily through AWS CDK and TypeScript.
• Develop and manage cloud environments, including networking, compute resources, data stores, secrets management, and platform automation.
• Architect and optimize CI/CD pipelines with advanced capabilities such as affected-only builds, remote caching, merge queues, and test optimization.
• Implement DevSecOps practices by integrating security controls, compliance automation, artifact signing, and security evidence generation directly into development workflows.
• Build and maintain secure architectures based on Zero Trust principles, including identity integration, mTLS, policy-as-code authorization, and continuous security monitoring.
• Leverage AI-assisted development tools to accelerate engineering workflows while ensuring all generated code meets production-quality standards.
• Improve engineering processes by maintaining development frameworks, standards, and automated workflows that increase team productivity.
• Support full-stack engineering efforts by troubleshooting issues across application code, infrastructure, databases, and deployment systems.
• Ensure platforms meet strict security and compliance requirements, including DoD Impact Level 4 (IL4) standards and related security frameworks.
• Collaborate with engineering teams to improve reliability, scalability, and overall developer experience.

Requirements

• Eligibility to obtain a U.S. Secret security clearance.
• 7+ years of experience building, deploying, and operating production cloud platforms.
• Strong experience with Infrastructure as Code, especially AWS CDK and TypeScript.
• Deep understanding of cloud architecture, distributed systems, DevOps practices, and production engineering.
• Hands-on experience with agentic AI development tools such as Codex, Claude Code, or similar solutions in real-world software environments.
• Strong software engineering background with experience in Node.js, PostgreSQL, and Prisma or similar database technologies.
• Experience with container orchestration platforms such as Kubernetes/EKS or ECS.
• Proven experience operating secure cloud infrastructure in high-compliance environments, ideally supporting DoD IL4 or similar regulated systems.
• Knowledge of CI/CD architecture, automated testing strategies, observability, and infrastructure optimization.
• Experience with security hardening practices, including STIG requirements and secure container or operating system configurations, is preferred.
• Familiarity with developer experience improvements, build performance optimization, legacy system modernization, or workflow orchestration tools such as Temporal is a plus.
• Strong problem-solving skills with the ability to work across the entire technology stack.

Benefits

• Competitive compensation package based on experience, technical expertise, certifications, security clearance level, and market factors.
• Fully remote work opportunity within the United States.
• Opportunity to contribute to high-impact modernization projects supporting critical national missions.
• Work with advanced cloud technologies, AI-assisted development practices, and secure infrastructure solutions.
• Collaborative environment focused on engineering excellence, innovation, and mission-driven outcomes.
• Comprehensive employee benefits programs.
• Potential eligibility for performance-based or incentive compensation.
• Inclusive workplace committed to equal opportunity and professional growth.
