- Automate infrastructure provisioning and deployment processes using Infrastructure as Code (IaC) tools like Terraform or Pulumi.
- Design and operate scalable processes to provision cloud access and maintain least privilege.
- Participate in and support the incident detection and response process by enhancing observability and alerting and assisting the incident response team.
- Self-organize and prioritize activities independently.
- Support audits and first-party security questionnaires.
- Conduct and oversee security assessments and threat modeling exercises.
- Implement security controls within Kubernetes.
- Build DevSecOps tools/integrations.

- Knowledge of common web application vulnerabilities and the OWASP Top 10 framework.
- The ability to analyze and act on results from DAST and SAST tools (e.g., Tenable, Snyk).
- Skilled in DevSecOps principles and familiarity with CI/CD pipelines (GitHub Actions, Argo CD, Azure DevOps) to perform automated security testing.
- Experience deploying and customizing security tools to address threats and lower risk, including vulnerability scanners, static analyzers, web application firewalls (WAFs), intrusion detection/prevention systems (IDS/IPS), and endpoint security monitoring.
- A comprehensive grasp of cloud and network security, including an in-depth understanding of Kubernetes.
- Experience in GCP specifically with one or more of the following services: Security Command Center, GKE, Cloud IDS, Cloud Armor, and Secrets Manager.
- Experience in Azure specifically with one or more of the following services: Security Center, Azure PaaS App Services, VMs, Azure SQL, Front Door, and Key Vault.
