The role operates within a high-assurance environment and works closely with technical staff and vendors to ensure infrastructure solutions are secure, reliable, auditable and aligned with operational and security requirements. A strong focus on automation, infrastructure-as-code, and knowledge transfer is central to the role.

NV1 clearance is highly preferred.

What you'll do:

• Plan, deploy, configure and support infrastructure solutions across physical, virtual, network, storage and operating system layers within a discrete operational environment.
• Ensure reliable, secure and performant ingest of operational data into AFPNet networks and systems.
• Provide Infrastructure Engineer / Systems Administrator services under the direction of nominated AFP personnel.
• Provide technical direction and oversight to vendors delivering professional services on behalf of the AFP, ensuring compliance with security, architectural and operational constraints.
• Design, implement and maintain Infrastructure-as-Code using Ansible and Git/GitLab, including CI/CD pipelines to support safe, repeatable and auditable change.
• Configure and administer Linux (Ubuntu) systems, including hardening, patching, optimisation and troubleshooting.
• Configure and support Windows Server systems and services where required (e.g. Active Directory, ADFS, certificate services).
• Manage and optimise virtualised environments using VMware vSphere and ESXi, including lifecycle management and performance tuning.
• Support enterprise storage, backup and recovery solutions to ensure data integrity, availability and compliance.
• Contribute to secure network design and operations, including firewall policy management, segmentation and secure connectivity.
• Work effectively as part of a small, multidisciplinary team in a high-security operational context.

What you'll bring:

• Proven experience designing, deploying and supporting Linux-first (Ubuntu) infrastructure in secure or high-assurance environments.
• Demonstrated experience configuring and maintaining Windows Server systems and services, including Active Directory and related components.
• Strong hands-on experience with automation and Infrastructure-as-Code, including Ansible playbooks/roles and Git/GitLab workflows and CI/CD pipelines.
• Demonstrated expertise with VMware vSphere and ESXi, including lifecycle management, performance optimisation and operational support.
• Experience designing and supporting infrastructure across the full stack (physical, virtual, network, storage).
• Networking experience with Cisco firewalls and switches, including policy configuration, network segmentation and secure connectivity.
• Ability to design and operate solutions that address security, testing, operational and lifecycle requirements (monitoring, logging, backup, patching, runbooks).
• Strong documentation skills, with the ability to produce clear procedures, diagrams and technical artefacts to support knowledge transfer.
• Ability to work collaboratively with internal teams and external vendors in a controlled and security-focused environment.
• Desirable experience with containers, monitoring and alerting platforms, data ingest pipelines, and Federal Government security and change management frameworks.
