Responsible for building and delivering the Linux automation layer, identity federation with Active Directory, secrets management, and certificate lifecycle automation. Collaborates with the architecture lead on identity design and with platform engineers on IaC integration.
Key Responsibilities
* Own Linux automation, configuration management, and infrastructure-as-code delivery
* Harden Linux and infrastructure platforms to meet security and compliance requirements
* Deploy and configure SSO/identity federation with existing Active Directory
* Integrate Linux infrastructure with the existing Windows / Active Directory environment (host enrolment, authentication, authorization, and access control)
* Design and deliver secrets management for dynamic credentials and PKI
* Design and deliver automated key and credential rotation for secrets, TLS/SSL certificates, and service credentials
* Extend JIT access models to on‑prem infrastructure
* Automate Linux OS patching and coordinate with existing Windows/VM patching tooling
* Automate certificate lifecycle management and integrate with infrastructure and security platforms
* Collaborate with the architecture lead on identity design and with platform engineers on IaC integration
Required Skills
* Strong Linux administration skills (preferably RHEL-based) including system administration, networking, troubleshooting, and hardening.
* Hands‑on experience with Ansible, Bash, or Python to automate infrastructure, configuration, and operational tasks.
* Practical experience using OpenTofu / Terraform to provision and manage infrastructure in a repeatable and maintainable way.
* Experience deploying and configuring an SSO/identity broker federated with existing Active Directory, including group‑to‑role mapping. Ideally experience with Kerberos‑based desktop SSO.
* Working knowledge of Active Directory, domain controllers, DNS integration, group policies, and identity dependencies for applications and infrastructure.
* Hands‑on experience integrating Linux hosts and services with Active Directory (e.g. SSSD / realmd / winbind for host enrolment, Kerberos‑based authentication, AD‑backed sudo and access control, cross‑platform file/share access)
* Experience designing and delivering secret management for dynamic credentials and PKI, including automated rotation policies.
* Experience automating certificates and credential lifecycle management (request, renewal, rotation, deployment) and integrating it with infrastructure and security platforms.
* Working knowledge of virtualization platforms (e.g. VMware vSphere, Hyper‑V, KVM-based platforms such as Proxmox, OpenShift Virtualization).
* Basic exposure to container platforms (e.g. OpenShift).
* Experience with Ansible automation platforms (e.g. AWX) for runbook automation.
* Experience with golden image building tools (e.g. Packer).
* Experience with security compliance scanning (e.g. CIS hardening baselines).
