Full Stack Software Developer Contract Jobs in Fort Collins, CO

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI‑powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting‑edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

Anduril's Air & Missile Defense Radar team develops cutting‑edge tracking algorithms and software systems that detect, track, and characterize airborne threats in real‑time. Working in small, focused teams, our software engineers design and implement sophisticated tracking solutions that protect lives and critical assets. Our work spans the full spectrum—from developing novel multi‑target tracking algorithms to building high‑performance distributed systems that process massive amounts of sensor data in milliseconds.

We are seeking a Software Engineer to bridge the gap between software engineers working on tactical code and the DevSecOps engineers maintaining cloud infrastructure. You will build and maintain the secure automation infrastructure that powers our radar tracking deployments, create testing and analysis tools to support tactical software, and accelerate developer workflows. You'll design CI/CD pipelines, architect core tooling, implement Infrastructure‑as‑Code, and establish continuous compliance workflows that enable our engineering teams to deploy updates rapidly while meeting stringent DoD and IC security requirements.

• Design and implement secure CI/CD pipelines, enabling automated build, test, and deployment of radar tracking software across multiple enclaves
• Collaborate with software engineers to optimize the build and test processes, reduce deployment friction, and integrate security controls early in the development lifecycle
• Work alongside tactical software developers to identify pain points and process deficiencies and architect durable solutions
• Build Infrastructure‑as‑Code frameworks (Terraform, Ansible, or similar) to provision and configure development, test, and production environments that meet DISA STIG and NIST 800‑53 requirements
• Automate security compliance workflows, including STIG scanning, vulnerability assessment, configuration validation, and compliance reporting for continuous monitoring
• Develop containerization and orchestration solutions (Docker, Kubernetes) tailored for classified networks with appropriate security hardening
• Create monitoring and logging infrastructure to support security operations, troubleshooting, and incident response
• Partner with system administrators and ISSM/ISSO personnel to ensure deployed systems meet customer security requirements

• 5+ years of experience and a Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience)
• Strong hands‑on experience with CI/CD tools such as GitLab CI, Jenkins, GitHub Actions, or similar
• Proficiency in a variety of programming languages such as Python and C++
• Understanding of software engineering fundamentals: design patterns, testing, version control, and debugging
• Familiarity with Infrastructure‑as‑Code using Terraform, Ansible, Puppet, Chef, or similar tools
• Working knowledge of containerization technologies (Docker) and orchestration platforms (Kubernetes, Docker Swarm)
• Understanding of Linux system administration, networking, and scripting (Python, Bash)
• Ability to obtain and maintain a U.S. Top Secret SCI security clearance

• Experience deploying and maintaining systems in classified DoD or IC environments
• Hands‑on experience with ATO processes, STIG implementation, and continuous monitoring for accredited systems
• Proficient in Python package development
• Familiarity with SCAP‑compliant scanning tools (OpenSCAP, Nessus, ACAS) and automated compliance frameworks
• Experience with secure software supply chain practices, artifact signing, and software bill of materials (SBOM)
• Knowledge of zero‑trust architectures and microsegmentation in Kubernetes environments
• Experience with GitOps workflows and declarative infrastructure management
• Proficiency with observability and monitoring tools (Prometheus, Grafana, ELK stack, Splunk)
• Understanding of PKI, certificate management, and secrets management solutions (Vault, AWS Secrets Manager)
• Experience with air‑gapped or disconnected network deployments
• Familiarity with DoD security frameworks (RMF, NIST 800‑53, DISA STIGs)
• Active U.S. Top Secret SCI clearance
• Relevant certifications such as Security+, CISSP, or AWS/Azure security certifications
