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

About The Role :

Immutable builds products for game studios. One side of the business is a marketing data platform that helps studios find and keep players.



The other is blockchain infrastructure, including our own Ethereum layer-2 network and Passport, a wallet players use to hold real digital assets. For a security engineer, this means a wide spread of work across web apps and APIs, AWS and GCP, and smart contracts where a bug has a dollar value attached.

You’ll join a security team of five and report to our Head of Security. Most of your time will be spent with the product engineering teams, reviewing current services, building threat models with them and fixing issues in their code. Our target is to fix 80% of vulnerabilities before they reach production, and this role is central to hitting it.
