In this role, you will focus on infrastructure and cloud security, with particular emphasis on web proxy solutions, OpenShift/Kubernetes security, service mesh technologies, and Infrastructure as Code (IaC). You will work closely with architecture, infrastructure, and application teams to assess security risks, strengthen existing solutions, and ensure that security best practices are embedded throughout the technology lifecycle.

Design, implement, configure, and harden web proxy solutions in complex enterprise environments.
Secure and support OpenShift/Kubernetes platforms, ensuring compliance with security best practices.
Implement and manage service mesh technologies, such as Istio and Red Hat Service Mesh, including traffic management, mutual TLS (mTLS), and security policy enforcement.
Develop and maintain Terraform-based Infrastructure as Code (IaC) solutions to automate secure infrastructure provisioning and configuration.
Assess and strengthen API security, network segmentation, certificate lifecycle management, and secrets management.
Conduct security assessments, identify vulnerabilities and misconfigurations, and define appropriate remediation plans.
Apply cloud-native security, container security, DevSecOps, and identity and access management (IAM) principles.
Collaborate with architects, infrastructure specialists, and application teams to integrate security into technical designs and delivery processes.
Provide expert guidance on security architecture, risk mitigation, and the implementation of pragmatic security controls.
