• Implement and maintain robust security controls to protect our cloud infrastructure and applications.
• Discover, remediate, and validate security issues across cloud infrastructure.
• Perform architectural/design reviews through a security lens and provide timely, actionable requirements and recommendations.
• Collaborate with security leadership, compliance, and engineering teams to execute security strategies.

• Propose and contribute to security and compliance improvements for nesto CI/CD pipelines and deployment processes.
• 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.

Who we're looking for

• 5+ years of experience working on a team focused on infrastructure and/or security.
• 5+ years of development experience (ideally GoLang, TypeScript/JS).
• 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.
• Experience writing infrastructure-as-code using tooling such as Terraform, Pulumi, and Helm.
• Knowledge of common security-related frameworks and benchmarks like CIS, NIST, and MITRE ATT&CK.
• An understanding of identity and access management (IAM) principles and cloud-native IAM solutions.
• Passionate about constant learning and sharing knowledge with others.

We definitely want to talk to you if you have/are
