Senior Platform Engineer

About Us 🚀: Immutable is the world's fastest-growing game platform, built to power the next generation of games. Immutable's full-stack product suite powers every stage of game creation and growth from infrastructure to player engagement.  Founded in 2018, we're one of the fastest Australian companies to reach unicorn status, raising more than AUD $400M+ at a valuation of AUD $3.5B. Today more than 700 games build on Immutable, and industry leaders like Ubisoft have chosen us as their partner for the future of gaming. Immutable Audience, our newest product line, is the fastest-growing SaaS in our history. We're growing faster than we ever have, and we're hiring the talent who'll take it further 🚀 A bit about the role 🤔 We're looking for a  Senior Platform Engineer to join our Platform team. This is a hands-on individual-contributor role for someone who sits genuinely in the middle, real infrastructure ownership and application development. Our Platform team exists to accelerate the rest of engineering. As our product teams build out Immutable Audience, our job is to make them faster and safer, removing toil, clearing blockers, and building the paved roads and self-service tooling that let teams ship without reinventing the foundations each time. It's a broad remit. In any given cycle you might be extending our internal Kubernetes operator (written in Go) that provisions services and their supporting AWS resources from a single manifest, improving our observability patterns, hardening reliability, or helping a team choose and integrate a new piece of technology. You'll work across the full stack of how we run software, a primarily AWS environment on EKS, GCP powering our data and CDP platform, Terraform, GitOps with Flux, and a Go backend. You'll own things end to end, set your own priorities with light direction, and have real influence over decisions that we'll build on for years. We're back in a scrappy scale-up phase, so there's a lot of room to shape foundations rather than inherit them. The team is Sydney-based and in the office three days a week.
