Profectus is seeking expressions of interest from experienced engineers to build, administer, and provide senior escalation support for secure Windows and Linux platforms in virtualised environments across Australian Government clients. You will work as part of a small, high-trust engineering team sustaining production systems and their supporting development environments, while contributing to ongoing feature development, automation, and configuration control. The scope is deliberately broad. We are equally interested in candidates from systems administration, network engineering, and cloud or virtualisation infrastructure backgrounds. If you have designed and built environments and want to stay close to the technology, much of the work will be familiar: configuration baselines, automated builds, monitoring, and platform and network troubleshooting, delivered inside a governed and secure environment.
Key Responsibilities

Replicate reported faults and develop, test, and verify resolutions
Perform system and network monitoring, and assess configuration compliance across the environment

Support system builds, updates, upgrades, and the release of additional features and functionality
Support the configuration and maintenance of network devices within the environment
Administer and maintain support and development environments
Baseline and maintain system configuration control, and document setting and network design changes




Develop and maintain standard operating procedures, build and load instructions, and other technical documentation
Contribute to training material development and transfer knowledge to support personnel

Experience developing and maintaining SOPs, build and load instructions, and technical documentation
Experience applying DevOps methodologies within a delivery team
Ability to operate effectively both independently and as part of a collaborative engineering team




Strong written communication skills and the ability to engage technical and non-technical stakeholders
A growth mindset and willingness to build capability across unfamiliar technologies
Software development experience on Linux and/or Windows platforms
Infrastructure as code and configuration management using tooling such as Ansible, Git, and comparable platforms
Experience with OpenStack, or with other virtualisation and private cloud platforms
Experience designing, architecting, or migrating infrastructure, network, or cloud environments
Experience with bespoke Windows and Linux standard operating environments (SOE)
Network, virtualisation, or cloud certifications
Experience with Jira or comparable incident and work management toolsets
ITIL v4 experience or certification
Understanding of systems engineering processes and the capability lifecycle
