DevSecOps Engineer

Kubernetes Security — Primary

• Harden GKE clusters — CIS benchmarks, pod security standards (restricted/baseline), and admission control policies.
• Implement and manage network policies to enforce east-west traffic segmentation between namespaces and services.
• Deploy and operate runtime security tooling (e.g. Falco) for threat detection inside cluster workloads.
• Manage Kubernetes RBAC with least-privilege principles. Audit and remediate overpermissioned service accounts.
• Secure the container supply chain — image scanning in CI (Trivy/Snyk), enforce signed images, and maintain a trusted registry policy.
• Implement Istio security controls — mTLS enforcement, authorisation policies, and east-west traffic observability.
• Continuously audit running workloads for security drift — privileged containers, host path mounts, and secrets in environment variables.

CI/CD & GitLab Security — Primary

• Secure the GitLab CI/CD pipeline end-to-end — protect runner environments, restrict pipeline permissions, enforce branch protection and MR approvals.
• Integrate SAST, DAST, dependency scanning, container scanning, and secret detection natively into GitLab CI. Own the triage and remediation workflow.
• Implement IaC security scanning (tfsec, Checkov) as a mandatory pipeline gate for all Terraform changes.
• Manage GitLab token hygiene — enforce expiry policies, rotate project tokens, and audit personal access token usage.
• Define and enforce pipeline security policies organization-wide using GitLab security policy-as-code.

Endpoint & Network Security — Primary

• Audit and reduce the external attack surface — inventory all public endpoints and drive internalization of services that do not need to be public.
• Implement and maintain WAF and Cloud Armor rules to protect externally exposed services.
• Enforce TLS certificate management — automate issuance, rotation, and enforce TLS 1.2+ across all endpoints.
• Manage bastion host security — enforce short-lived certificates (OS Login / IAP), eliminate persistent SSH keys, and log all administrative sessions.
• Own DNS security controls — DNSSEC, private DNS zones for internal services, split-horizon DNS where required.

Security Engineering & Automation

• Build security automation pipelines — policy enforcement, compliance checks, and vulnerability remediation as code.
• Instrument security observability in Datadog — threat detection dashboards and alert tuning for cloud and Kubernetes signals.
• Develop and maintain runbooks for security incidents, vulnerability response, and access reviews.
• Champion security training and awareness. Conduct secure code reviews and threat modelling workshops.

TECH STACK

Required

• GCP — Security Command Center, IAM, VPC Service Controls, Cloud Armor, Secret Manager, Binary Authorization
• AWS — GuardDuty, Security Hub, IAM, KMS, Macie, AWS Config
• Kubernetes — GKE hardening, pod security standards, network policies, RBAC, admission controllers
• GitLab — CI/CD security, SAST/DAST, dependency scanning, pipeline policy management
• Terraform — IaC security scanning (tfsec, Checkov), secure module design
• Datadog — security monitoring, threat detection, alert management
• Istio — mTLS, authorisation policies, service mesh security

Good to have

• Falco, OPA/Gatekeeper, HashiCorp Vault, Wiz/Orca/Prisma Cloud, Trivy/Snyk, SIEM (Splunk/Chronicle), Python or Go

Must have

• 7+ years in DevSecOps, cloud security, or infrastructure security engineering.
• Deep hands-on experience securing Kubernetes clusters in production — RBAC, network policies, pod security, and runtime protection.
• Proven experience with GCP and/or AWS security services and IAM design.
• Strong CI/CD security knowledge — pipeline hardening, secrets management, and integrated scanning.
• Experience internalising service endpoints and reducing cloud attack surface.
• Familiarity with HIPAA, SOC 2, or ISO 27001 compliance in regulated environments.
• Clear communication skills — able to explain a critical vulnerability to a CTO and write a runbook for an engineer.

Nice to have

• Certified Kubernetes Security Specialist (CKS).
• Google Professional Cloud Security Engineer or AWS Security Specialty certification.
• eBPF-based security tooling (Cilium, Tetragon), penetration testing, or red team experience.
• Threat modelling using STRIDE or PASTA. Service mesh security beyond Istio.
