TL;DR · Infrastructure Security Engineer

As an Infrastructure Security Engineer on the Security Engineering team, you will own the security architecture for production cloud environments including multi-account AWS, Kubernetes clusters, and the identity plane. You will build out cloud security visibility platforms, develop zero trust access strategies, and harden Kubernetes environments using RBAC and admission policies. Your daily work involves building agentic detection workflows, implementing shift-left security in pipelines, and managing secrets via Vault. The role requires proficiency in Go, Python, TypeScript, and Terraform while utilizing tools like GuardDuty, Datadog, and Okta. You will secure infrastructure supporting home acquisition, resale, mortgage, title, and escrow services. You must address technical challenges involving cloud-native security, identity-aware proxies, and securing AI-driven workflows that interact with production cloud infrastructure to ensure automated remediation of risks across the multi-cloud environment.

What you'll do

  • Manage the security architecture for production cloud environments including AWS accounts, Kubernetes clusters, and identity planes.
  • Build and operate a cloud security visibility platform integrated into engineering workflows for automated risk remediation.
  • Define and implement zero trust access strategies using device trust and identity-aware proxies.
  • Harden Kubernetes environments through RBAC, admission policies, workload identity, and runtime protection.
  • Develop agentic detection and response workflows using AWS primitives to automate alert investigation and remediation.
  • Implement shift-left security in CI/CD pipelines to catch infrastructure misconfigurations at the commit stage.
  • Manage cloud detection engineering by tuning GuardDuty, Security Hub, and CloudTrail logs for high-signal alerts.
  • Establish "secure by default" standards for AI-driven workflows and agentic systems interacting with production infrastructure.

What we're looking for

  • Must have 5+ years of cloud or infrastructure security experience with deep AWS expertise.
  • Proficiency in at least one programming language: Go, Python, or TypeScript.
  • Ability to read and write Terraform (HCL) and shell scripts.
  • Hands-on experience in Kubernetes security including RBAC, network policies, admission control, and workload identity.
  • Experience deploying and operating cloud posture and workload protection tooling such as Wiz, Prisma, Orca, or Datadog.
  • Demonstrated ability to build identity and access management solutions at scale with an identity-first mindset.
  • Proven track record of building agentic systems to automate and replace manual security work.
  • Must be based within commuting distance of the Miami office for in-person work four days per week.
