 * Experience with cloud security posture management tooling, infrastructure-as-code security scanning, or automated remediation
 * Experience with network security and isolation techniques including east-west controls, traffic inspection, and cloud network policy
 * Experience with eBPF for security monitoring and enforcement, or developing kernel security policies
 * Experience building secrets management or workload authentication systems, including familiarity with protocols such as OAuth 2.0, OIDC, SAML, or SPIFFE/SPIRE
 * Background building or operating security systems in environments that support research workflows and rapid iteration, Minimum education: Bachelor's degree or an equivalent combination of education, training, and/or experience

Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience

Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position

Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

## Description

* Build and maintain identity and secrets management systems, including credential issuance, rotation, and workload authentication across our multi-cloud environments
 * Contribute to cluster security controls including RBAC policies, namespace isolation, workload identity, and pod security
 * Implement and maintain cloud security controls including IAM, network segmentation, VPC architecture, and encryption across our multi-cloud and on-prem environments
 * Design and implement secure development frameworks and libraries that make secure coding the path of least resistance for our engineering teams, including service to service authentication, serialization libraries, and tool proxies.
 * Harden CI/CD pipelines against supply chain attacks through isolated build environments, signed attestations, dependency verification, and automated policy enforcement
 * Identify and remediate security gaps through code review, threat modeling, and hands-on debugging
 * Contribute to continuous cloud security posture management using infrastructure-as-code scanning, misconfiguration detection, and automated remediation
