Infrastructure Support Manager

Locations: Albury, Brisbane, Sydney, Melbourne, Perth, Canberra or remote within Australia About COSOL COSOL is a 25-year-old, ASX-listed asset management consulting and technology firm operating across asset intensive industries, including utilities, water, energy, mining, oil & gas, and transport. About the Role COSOL runs its own proprietary cloud environment, built on AWS over more than a decade, that hosts customer data and underpins the platforms our clients use every day. The Infrastructure Support Manager owns that environment, its performance, security, and reliability. Where our client facing teams build the dashboards, AI models, and analytics customers actually see, this role owns everything underneath, the infrastructure and backend those tools run on. This is a hands on, technical role with 1 to 2 direct reports in time. You'll be doing genuine engineering work yourself, not just directing others. You'll work closely with capability leads, delivery, technical, and commercial teams to maintain service standards, manage incidents, and contribute to infrastructure strategy and continuous improvement. Much of the team sits in Albury, NSW, while COSOL's head office is in Brisbane, Australia. This position can be worked remotely from anywhere in Australia. We have a preference for candidates based in Albury or Brisbane, while we're open to candidates based anywhere, including Sydney, Melbourne, and Perth.
