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.

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 OverviewThe 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 DescriptionWe'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 ResponsibilitiesDesign and build distributed services for vulnerability scanning, policy enforcement, and remediation workflowsDevelop 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 scaleBuild and maintain policy-as-code systems that programmatically enforce security policy in CI/CD pipelines and deployment configurationsDesign APIs and CLIs that integrate security tooling into developer workflows without creating frictionDevelop data pipelines that aggregate, normalize, and route findings from multiple scanning engines into vulnerability management systemsCollaborate with engineering teams across Anduril to understand their security needs and build tooling that addresses themEvaluate third-party security tools and build custom integrations or replacements where neededParticipate in on-call rotation for security tooling infrastructureRequired Qualifications5+ years of experience designing and developing production software systemsStrong proficiency in Go — this is the team's primary language for backend servicesExperience building distributed systems or data pipelines (event-driven architectures, message queues, APIs, worker systems)Proficiency with Python for scripting, automation, and toolingExperience 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 itStrong communication skills with the ability to work across teamsEligible to obtain and maintain active U.S. Secret security clearancePreferred QualificationsExperience with CI/CD systems (CircleCI, GitHub Actions) and building integrations for developer workflowsFamiliarity with container security concepts, SBOM generation tools (Syft), and vulnerability scanners (Trivy, Grype, Semgrep)Experience with Terraform and infrastructure-as-codeExperience with policy-as-code frameworks (OPA/Rego, Conftest)Background in application security or product security engineeringExperience with Kubernetes and container orchestrationFamiliarity with Nix build systemsUS 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.
