Core Responsibilities
- Monitor emerging vulnerabilities and regularly assess the security posture of Kubernetes, OpenShift, underlying Linux hosts, container workloads, and shared platform services, then identify and prioritize risks and control gaps and drive remediation to completion.
- Develop automation for continuous security posture assessment, streamline vulnerability management, and remediate repeatable, well-understood security issues where appropriate.
- Implement and improve Kubernetes and OpenShift security controls, including RBAC, Security Context Constraints (SCCs), Pod Security Admission, network policies and segmentation, ingress and service mesh security (including mTLS and authorization policies), secrets and certificate management, workload identity, and policy-as-code controls.
- Configure, integrate, maintain, and optimize security tools to provide accurate, actionable insight into platform vulnerabilities and risks.
- Evaluate and recommend security tools and technical controls to improve vulnerability management, security monitoring, access visibility, and compliance.
- Strengthen DevSecOps and software supply-chain security across CI/CD and GitOps workflows, including vulnerability and secret scanning, dependency and container image controls, SBOMs, image provenance, and workflow permissions.
- Partner with platform and application engineers to interpret findings, select practical remediation approaches that balance security with reliability, developer experience, and business needs, and incorporate security into platform designs and delivery workflows.
- Document security findings, control decisions, remediation approaches, exceptions, standards, and recurring processes, and communicate material risks to technical and non-technical stakeholders.
- Participate in security investigations, incident response, a shared on-call rotation, and scheduled platform maintenance, including some work outside normal business hours.
Platform and Technology Scope
- Work primarily with Kubernetes and Red Hat OpenShift environments across on-premises and cloud-connected infrastructure and shared application platforms running within them, including MongoDB, PostgreSQL, Redis, RabbitMQ, and Apache Solr.
- Support a delivery ecosystem that includes GitHub Actions, Codefresh, Argo CD, GitOps, Helm, APIs, and configuration-as-code practices.
- Use Wiz, Tenable, and Red Hat Advanced Cluster Security (ACS) for vulnerability management, Kubernetes and container security, compliance, and risk visibility. Experience with these platforms is helpful, and comparable security technology experience is also relevant.
- Expected use of approved AI-assisted engineering tools to automate security analysis, triage, and remediation workflows. Sound judgment, validation of results, and secure data-handling practices are required.
Required Qualifications
- Bachelor’s degree in Cybersecurity, Computer Science, Information Technology, or a related field, or an equivalent combination of education, training, and practical experience.
- 3 to 5 years of experience in security engineering, platform security, infrastructure security, DevSecOps, vulnerability management, or a related technical field.
- Hands-on experience securing Kubernetes or containerized platforms, including identity and access, workload security, network controls, secrets, images, and secure configuration.
- Experience using vulnerability and security findings to assess risk, prioritize remediation, and improve security posture, including configuring or maintaining the security tools that produce those findings.
- Experience scripting or building automation with Python, PowerShell, Bash, or a similar language.
- Understanding of DevSecOps and secure software-delivery practices, including CI/CD, container images, application dependencies, and software supply-chain risk.
- Ability to troubleshoot technical issues, analyze risk, document findings, and complete assigned work with limited direction.
- Strong written and verbal communication skills, sound engineering judgment, and ability to collaborate with platform engineers, developers, security teams, and compliance partners.
Preferred Qualifications
- Experience applying Kubernetes security practices in Red Hat OpenShift, including SCCs, operators, and cluster policy.
- Experience with Red Hat Advanced Cluster Security (ACS), Wiz, Tenable, or comparable container security, cloud security, and vulnerability-management platforms.
- Hands-on experience implementing controls such as SAST, SCA, secret scanning, SBOM generation, container scanning, image signing, or provenance.
- Ability to read and review code in at least one common language such as Java, TypeScript, Python, or Go, and familiarity with common application and API vulnerability classes.
- Experience securing service mesh (such as Istio), ingress, API gateways, or Linux hosts.
- Experience with GitOps, Helm, Ansible, Terraform, Kubernetes operators, or YAML-based pipeline automation.
- Familiarity with security standards and practices such as OWASP Top 10, OWASP API Security Top 10, NIST Secure Software Development Framework, CIS Benchmarks, SLSA, or MITRE ATT&CK.
- Relevant security or cloud certifications, such as Security+, CISSP, CCSP, or Certified Kubernetes Security Specialist (CKS).
