  About Us

  
  

  Immutable is the world’s fastest-growing game platform, built to power the next generation of games. We aim to drive the next evolution of gaming, combining performance, digital ownership and cutting-edge technology to help games grow and succeed. At the intersection of AI-driven analytics, high-performance growth tools, and seamless digital ownership, our technology helps studios attract, engage, and scale player communities across both Web2 and Web3.

  
  

  Founded in 2018, Immutable is one of Australia’s fastest companies to reach unicorn status, raising more than AUD $400M+ with a valuation of AUD $3.5B. Today, more than 700 games are building on Immutable, and industry leaders like Ubisoft have chosen us as their partner for the future of gaming.

  
  

  Over 6 million players use Immutable Passport, our unified identity enabling frictionless cross-game experiences, and our Immutable Audience platform has become the fastest-growing SaaS product line in our history. We're scaling rapidly, backed by a global team of creators, engineers, and gamers united by one mission: to build the most valuable growth layer in gaming and redefine how games launch, scale, and succeed.

  
  

  About The Role

  
  

  As Immutable scales rapidly, we’re investing in building out a world-class security function. We’re looking for a Senior Security Engineer to join our growing security team to lead the charge in detection engineering, response automation, and adversary simulation.

  
  

  This role is ideal for someone who thrives in fast-paced environments, deeply understands detection and response, and wants to shape security strategy at the core of a web3 company handling digital asset ownership at scale.

  \n

  
  

  You’ll Be Empowered To

  • Own and operate our Security Operations (SecOps) and SOAR platforms, building playbooks and automation to reduce response time and improve signal fidelity.
  • Design and implement detection pipelines that surface high-fidelity alerts and enable effective incident triage.
  • Write custom detections not just enabling built in features
  • Lead initiatives to harden our endpoints, SaaS controls, and workforce identity systems.
  • Deploy and manage security agents (EDR, device assurance, secrets managers) across our environment.
  • Collaborate cross-functionally to integrate security deeply into our SDLC and product architecture.
  • Leverage AI, scripting (Python, Golang), and automation to reduce toil and scale our small but mighty security function.
  • Operate with a “crown jewels” strategy—prioritising what matters most and moving fast where it counts.

  
  

  We'd Love You To Bring

  • Proven experience in detection and response engineering, security automation, or security operations in a product or platform company.
  • Demonstrated ability to align technical actions with strategic security outcomes.
  • Experience building pipelines that ingest, enrich and route data to security platforms.
  • Curiosity and passion for threat modelling, attack simulation, and adversary behaviour.
  • A pragmatic mindset: no cargo culting, just what works—incremental wins over theoretical perfection.

  Strong hands-on knowledge of:

  • macOS internal operating system knowledge
  • Cloud-native services (AWS/GCP)
  • SOAR tools and detection platforms
  • Endpoint agents like Kolide, Santa, or Crowdstrike
  • Identity protocols (OIDC, SAML), RBAC/least privilege

  Bonus Points For ✅: Experience in web3, blockchain, or crypto threat environments.

  
  

  Why You’ll Love It Here

  • We interface with adversaries regularly and need to push the boundaries of macOS security to protect our Web3 assets.
  • Shape the future of security in a frontier industry (crypto/web3)
  • Work alongside a high-performance team with agency, autonomy, and impact
  • Focus on deep work, tooling, and effectiveness—not firefighting
  • Partner with passionate engineers and leaders who value security
  • Move fast: deliver results in days, not quarters
