Senior Systems Engineer

Senior Systems Engineer Sydney | Melbourne | Brisbane | Hybrid Work Model | Competitive base + super + benefits We are not your typical internal IT team. We are technically sharp, curious and improvement focused, and we are looking for a Senior Systems Engineer to own and mature the platforms Orro runs on. Orro designs and operates digital infrastructure for some of Australia's biggest brands, and we hold our own internal environment to exactly the same standard. This is the senior technical seat in the team. You will set the standards, lead the uplift work from design through to handover, and lift the capability of the engineers around you. About Orro We're an Australian success story, now close to 500 people strong, delivering secure, end to end digital solutions across cloud, collaboration, cyber security, data services and network infrastructure, all backed by over 20 years of experience. Trusted by some of Australia's biggest brands, Orro leads the way in designing, building and operating digital infrastructure that delivers greater efficiency, agility, performance and resilience. Our solutions take the stress out of tech for more than 400 businesses and over 20 million Australians every single day. Our mission? To create "future now" solutions making it faster, simpler and safer for people to access, store and share information, wherever they are and whoever they're with. But more than that, we know that real impact comes from connecting people, not just machines. That's why we take the time to understand our clients; how they work, what matters to them, and where they're headed so we can deliver not just what they need today, but what they'll need next. With offices in Sydney, Melbourne, Canberra, Brisbane and Perth, and teams across New Zealand, the Philippines and the UK, Orro is known for delivering future ready solutions, backed by deep expertise, genuine human insight and lasting partnerships.
