Senior IT Security Engineer, Space with Security Clearance

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. ABOUT THE TEAM Anduril's Space team is dedicated to expanding our AI-powered capabilities into the final frontier, enhancing Space Domain Awareness, Space Control, and Command and Control for U.S. military and allied partners.

We're developing fully integrated hardware and software systems, including Lattice for Space Missions and modular payloads, to address growing threats in space and ensure our Guardians maintain a decisive advantage in this contested warfighting domain. ABOUT THE JOB We are seeking a Senior IT Security Engineer to architect, build, and own classified infrastructure for Anduril's Space team from the ground up.

This is a foundational role — you won't be inheriting an existing environment, you'll be designing and standing up the systems, standards, and processes that the team will rely on as it scales. That means making decisions about architecture, tooling, and automation frameworks, then implementing and hardening them to full compliance. You'll work at the intersection of security, infrastructure, and engineering to ensure our classified environments are built right from day one and remain resilient, compliant, and mission-ready. WHAT YOU'LL DO

• Design and build classified infrastructure from scratch, including server environments, virtual platforms, networking, and enterprise services — establishing the architecture and hardened baselines the Space team will operate on
• Define and implement STIG compliance strategies across Windows, RHEL, and VMware, using SCAP, SCC, and manual validation; stand up repeatable processes for ongoing compliance scanning and remediation
• Architect and deploy virtual infrastructure (primarily VMware vSphere, and potentially vSAN and Horizon/VDI), making foundational decisions on topology, resource allocation, and scalability
• Build out enterprise services from the ground up, including Active Directory, DNS, DHCP, WSUS/patch repositories, and repository servers
• Develop automation frameworks using Ansible, scripting (PowerShell, Bash, Python), and infrastructure-as-code practices to ensure environments are reproducible, consistent, and minimally dependent on manual intervention
• Establish monitoring, alerting, and incident response processes for system health, performance, and security posture
• Lead vulnerability remediation efforts, driving technical implementation for CAT I/II/III findings and partnering with ISSO/ISSM stakeholders to meet required timelines
• Design and implement backup and disaster recovery strategies, defining RPO/RTO targets and validating them through regular testing
• Guide environments through the ATO process, producing documentation, compliance evidence, and technical demonstrations for security assessments
• Create comprehensive runbooks, architecture documentation, and knowledge transfer materials to enable the team to scale beyond a single point of ownership REQUIRED QUALIFICATIONS
• 7+ years administering and hardening Windows Server and Linux (RHEL) in classified or regulated environments
• Demonstrated experience building infrastructure from scratch, not just maintaining existing environments
• Deep knowledge of STIG application and validation using SCAP/SCC tools, with the ability to design compliance programs, not just execute checklists
• Strong VMware vSphere experience, including architecture decisions, provisioning, and patching
• Experience standing up and managing Active Directory, DNS, DHCP, and enterprise patch management in new environments
• Advanced scripting and automation skills (PowerShell, Bash, or Python) with hands-on Ansible experience
• Eligible to obtain and maintain an active U.S. Secret security clearance

PREFERRED QUALIFICATIONS

• Experience architecting VMware vSAN and Horizon/VDI environments
• Familiarity with engineering applications such as Siemens NX, Teamcenter, or other CAD/CAM/CAE software
• Track record of leading environments through the full ATO lifecycle
• Experience mentoring junior administrators or leading small infrastructure teams
• Relevant certifications such as CompTIA Security+, RHCSA, RHCE, VCP, or CISSP   US Salary Range$166,000—$220,000 USD
