Senior Software Engineer, Security Applications & Tools at Andurilindustries

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. Team Overview The Security Applications & Tools (SAT) team within Lattice Platform Security builds custom software systems that detect, manage, and remediate vulnerabilities across Anduril's product ecosystem at scale. We don't just deploy scanners — we design and build distributed scanning infrastructure, policy enforcement engines, and vulnerability management platforms from the ground up. Our stack includes event-driven architectures on AWS, custom Go services, policy-as-code systems, and integrations that span CI pipelines to production environments. Job Description We're looking for a senior software engineer to design and build the systems that keep Anduril's software secure. This is a software engineering role first — you'll architect distributed systems, write production Go and Python, build APIs, and operate services at scale. The domain is security, but the work is building real software: custom scanning orchestration pipelines, policy engines that evaluate thousands of configurations against security rules, and data systems that track vulnerabilities across an entire product ecosystem. If you want to write code that solves hard engineering problems in the security space rather than configure off-the-shelf tools, this is the role. Key Responsibilities • Design and build distributed services for vulnerability scanning, policy enforcement, and remediation workflows • Develop and extend the team's scanning orchestration platform — an event-driven architecture built on AWS (SQS, Lambda, S3, ECR) that processes scan events at org-wide scale • Build and maintain policy-as-code systems that programmatically enforce security policy in CI/CD pipelines and deployment configurations • Design APIs and CLIs that integrate security tooling into developer workflows without creating friction • Develop data pipelines that aggregate, normalize, and route findings from multiple scanning engines into vulnerability management systems • Collaborate with engineering teams across Anduril to understand their security needs and build tooling that addresses them • Evaluate third-party security tools and build custom integrations or replacements where needed • Participate in on-call rotation for security tooling infrastructure Required Qualifications • 5+ years of experience designing and developing production software systems • Strong proficiency in Go — this is the team's primary language for backend services • Experience building distributed systems or data pipelines (event-driven architectures, message queues, APIs, worker systems) • Proficiency with Python for scripting, automation, and tooling • Experience with cloud infrastructure (AWS preferred: Lambda, SQS, S3, ECR, or equivalent) • Ability to read and understand security tool output (vulnerability reports, SBOMs, static analysis results) and build systems around it • Strong communication skills with the ability to work across teams • Eligible to obtain and maintain active U.S. Secret security clearance Preferred Qualifications • Experience with CI/CD systems (CircleCI, GitHub Actions) and building integrations for developer workflows • Familiarity with container security concepts, SBOM generation tools (Syft), and vulnerability scanners (Trivy, Grype, Semgrep) • Experience with Terraform and infrastructure-as-code • Experience with policy-as-code frameworks (OPA/Rego, Conftest) • Background in application security or product security engineering • Experience with Kubernetes and container orchestration • Familiarity with Nix build systems US Salary Range$191,000—$253,000 USDThe salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations.

Additional work-life services, such as legal and financial support, are also available. • Professional Development: Annual reimbursement for professional development • Commuter Benefits: Company-funded commuter benefits based on your region. • Relocation Assistance: Available depending on role eligibility.
