Senior Site Reliability Engineer

Welcome to our World of Cold! At Ao. Frio, we are global leaders in providing IoT solutions to the food and beverage industry. Our innovative technology and dedicated team have positioned us at the forefront of our market. Every Ao. Frio controller, monitor and gateway in the field depends on a platform underneath it: the AWS infrastructure, the databases, the pipelines that ship code safely at 2am if it has to.

You'll own that platform end to end from how it's built, how it scales, how fast we know when something's wrong to how quickly we fix it. You'll set the standard other engineers follow and you'll work through complex, ambiguous problems with minimal oversight. You will do: Lead the design and delivery of Ao.

Our controllers, monitors and gateways sit inside coolers for Coca-Cola, Pepsi. Co and AB In. Bev, and the software on top turns them into data our customers actually act on. Energy saved, stock protected, technicians sent to the right site. We run supply chain, logistics and R&D out of our Auckland HQ, with offices in four countries and people in twelve.

It's a small enough team that your work is visible, and a global enough business that it matters. What it's like to work here We're a global business with the corporate parts that come with that and we're also a place where plenty of things don't have a process yet. Some areas are polished, others you'll end up shaping yourself.

If you like a bit of room to do that, you'll be fine here. The Auckland office is properly international and the personalities are all over the place. Quiet, loud, neurodiverse, people at every stage of life. Nobody has to fit a particular mould to do well here. On Thursdays you might also run into a dog. On AI: we use it, we pay for premium tools and we'd rather you spent your time on hard problems than on boilerplate.

If you want to bring AI into how you work or into what we build, you won't need to make a business case for it first. What you'll enjoy at Ao. Frio: Southern Cross Wellbeing.
