Senior Platform Engineer

📋 Job Overview

Immutable is the world's fastest-growing game platform, built to power the next generation of games. We sit at the intersection of AI-driven analytics, high-performance growth tools and seamless digital ownership, helping studios attract, engage and scale players.

🏢 About Immutable

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 scaling fast, and that's the fun part. 🚀

🎯 The Role

You'll be empowered to own and evolve our AWS and Kubernetes (EKS) foundations, from VPC upwards, develop and release Infrastructure as code, partner closely with security, product and data teams, define SLOs, SLIs, monitoring, alerting and incident response practices, set the bar for observability excellence within the organisation, measure systems' health, scalability and performance metrics and identify areas of improvement, ensure our incident management processes, automation, and remediation are world-class, and work as a deep technical expert on the services we have ownership over.

📌 Required Qualifications

• Hands-on ownership of data reliability and observability: freshness, anomaly and schema-drift monitoring and data SLOs
• Deep AWS fundamentals: EKS/Kubernetes as a day-one runtime, Lambda/serverless, networking, multi-AZ
• Infrastructure-as-code (Terraform), CI/CD, and observability experience
• A real silent-failure story, caught or missed, that changed how you work
• Solid Go (or a strong track record of picking up new languages fast)
• Comfort with AI-assisted development
• Experience with identity resolution and consent or auth data modelling
• On-call ownership with considered views on alert fatigue
• High ownership, candour and a pragmatic, fix-it-while-live disposition
