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

- Act as a senior escalation point for the diagnosis and resolution of complex platform and network incidents within agreed service levels
- Replicate reported faults and develop, test, and verify resolutions
- Perform system and network monitoring, and assess configuration compliance across the environment
- Write and maintain scripts and automation to support system builds, application installation, configuration, and customisation
- 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 environment 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
- Provide surge support for onsite activities as required
- Provide technical advice that accounts for broader business and operational requirements

Required Experience

- Demonstrated system administration and customisation experience across both Linux and Windows servers and applications
- Demonstrated scripting and automation capability using Python, PowerShell, or UNIX shells, applied to installation, configuration, and repeatable build processes
- Experience working within virtualised or private cloud infrastructure
- Working knowledge of network fundamentals, including routing, switching, firewalls, and the configuration of network devices
- Sound fault-finding and diagnostic skills on issues escalated beyond frontline support, including working through incident management systems and toolsets
- 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




- Solid 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
- Experience supporting systems operating in distributed, remote, or field-based environments
- Experience working within an agile delivery framework
- Relevant tertiary qualifications or industry certifications in a related discipline

Security Clearance Requirements

- Must be an Australian Citizen
- Must hold a current AGSVA NV2 Security Clearance
