Responsibilities
Build and operate production security controls across AWS and Kubernetes platform
Design and implement guardrails that make secure delivery the default
Implement CI/CD security automation and developer-facing security workflows (SAST/SCA, secrets scanning, IaC scanning, container scanning)
Implement software supply chain controls (SBOM, artifact/image signing and verification, provenance and promotion workflows)
Enforce Kubernetes policy and admission controls (policy-as-code) that encode platform security guardrails
Co-own AWS security guardrails with Platform/SRE (IAM patterns, logging and detection, network and encryption baselines)
Partner with Security/GRC on control interpretation and evidence needs; implement controls in engineering systems and pipelines
Design, build, and maintain CI/CD security controls that scale across repositories and teams
Implement Kubernetes security architecture and guardrails (RBAC hardening, workload security baselines, admission policies, network policies, and safe multi-tenant patterns as applicable)
Improve container security end-to-end: base-image strategy, vulnerability scanning, registry controls, image signing, and promotion workflows
Operationalize vulnerability management with risk-based prioritization, measurable remediation SLAs, and dashboards/metrics (MTTR, exposure trends, top recurring root causes)
Drive developer enablement: clear documentation, lightweight design reviews/threat modeling for high-impact changes, office hours, and high-signal guidance embedded in tooling
Respond to incidents and on-call rotation related to platform security controls and pipeline reliability
Qualification
Required
5+ years of experience in DevOps/SRE/Platform Engineering and/or Security Engineering with a strong automation and delivery focus
Hands-on experience securing AWS environments: IAM (least privilege), network controls, encryption (KMS), and centralized logging/detection
Strong Kubernetes security experience (EKS or equivalent): RBAC, workload hardening, and policy enforcement via admission control
Experience integrating security into CI/CD pipelines and developer workflows (SAST, SCA, secrets scanning, container scanning, IaC scanning)
Infrastructure as Code proficiency (Terraform, CloudFormation, CDK, or Pulumi) and ability to embed guardrails into IaC workflows
Proficiency scripting/coding (e.g., Python, Go, Bash) to build integrations, automations, and internal tooling
Able to communicate risk and tradeoffs clearly and pragmatically to engineers; improves signal-to-noise rather than adding friction
Preferred
Experience with Kubernetes policy-as-code tooling (OPA/Gatekeeper, Kyverno) and secure workload identity patterns (OIDC/IRSA)
Experience with software supply chain security: SBOM generation and management, signing/verification (e.g., cosign), and provenance concepts
Experience building ‘golden paths' or internal developer platforms that improve both delivery velocity and security outcomes
Familiarity with regulated delivery expectations (NIST SP 800-171/CMMC) and evidence-driven control implementation
Benefits
100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family
Unlimited PTO, with your manager’s approval
Flexible work environment where you manage your work day
