Senior Infrastructure Architect

• Be part of a growing mining company with a portfolio of international operations and projects


• Drive reliability, security, and scalability across core infrastructure systems.


• Work within the Corporate Office in the James Street precinct in a 2 Year Fixed Term position

PanAust Limited (“PanAust”) is an Australian-headquartered copper and gold producer in Laos, with pre-development and exploration assets in Laos, Papua New Guinea (PNG) and Chile. Reporting directly to the Group IT Manager, this is an opportunity to join PanAust during an exciting period of revitalising its development opportunity pipeline.

Our Assets

In Laos, PanAust’s subsidiary, Phu Bia Mining Limited, operates the Phu Kham Copper-Gold and Ban Houayxai Gold-Silver Operations. Both are world-class, award-winning operations with strong operational, safety and sustainability credentials.

In PNG, PanAust owns the Frieda River Copper-Gold Project, one of the world’s largest known undeveloped copper and gold deposits.  The project will help supply the copper required to facilitate the renewable energy transition.  Frieda River is a sustainable, nation-building project which includes the development of a hydropower facility and public use infrastructure that will advance one of the least developed regions in PNG.

In Chile, PanAust owns 100% of the Carmen copper gold project and 66% of the Inca de Oro copper gold project.  Both are promising pre-development assets, which are being progressed by PanAust.

The Role

The Principal Infrastructure Architect plays a strategic, and technical leadership role, in designing and overseeing the implementation of robust, scalable, and secure IT and OT infrastructure across PanAust operations in Laos, PNG, Australia and Chile. This includes servers, storage, cloud platforms, networking, communications, and operational technologies.

The role, which is a 2 year fixed-term position, ensures alignment of infrastructure solutions with business goals, operational continuity, and industry best practices—particularly within the demanding, remote, and safety-critical contexts of mining operations.

• Translate business requirements into technical specifications and costed solution designs


• Integrate cybersecurity, data protection, and compliance requirements into infrastructure designs (e.g. Essential 8, OT5, Mining-specific controls)


• Ensure appropriate network segmentation and remote site resilience to reduce operational risk


• Maintain architectural documentation, principles, and decision records


• Evaluate infrastructure health and performance, identifying opportunities for standardization and cost optimization

To be successful in this role, you will require:

• Minimum 10 years' experience in infrastructure or systems architecture roles
