Immutable's full-stack product suite powers every stage of game creation and growth from infrastructure to player engagement.

Today more than 700 games build on Immutable, and industry leaders like Ubisoft have chosen us as their partner for the future of gaming. We're growing faster than we ever have, and we're hiring the talent who'll take it further ? 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 new 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. Own the AI agents that review pull requests for security issues and triage incoming bugs A security context layer (threat models, asset inventory, past findings) that lets those agents triage and propose fixes with less human input Application security depth. You can find a broken auth flow or an injection bug in code, explain why it happened and fix it properly. You're also a capable software engineer who ships production code,



whether that's a fix in someone else's service or a tool you built from scratch. It might be an agent, an automation or an internal tool, and you can tell us what worked, what didn't and how you knew. Solid AWS security experience will help a lot (IAM, network controls, secrets, misconfigurations). Side projects and open source work tell us a lot, so please include them. You'll enjoy this if you like autonomy, work well beside engineers and are happy to help out in other parts of security when a small team needs it. It's probably not a fit if you'd rather report findings than fix them. Web3 experience, such as wallet, smart contract or dApp security. You can learn it here, but it'll help from day one.
