About Us 🚀Immutable is a global technology company, powering the leading platform for building games on Ethereum. We are on a mission to build the future of gaming by redefining how games are played and discovered. Founded in 2018, Immutable is one of the fastest Australian companies to hit unicorn status, having raised more than AUD $300M+ and a valuation of AUD $3.5 billion.Currently, the Immutable Group consists of the Immutable Platform, the leading platform for building games on Ethereum powering successful games like RavenQuest and Immortal Rising 2, and Immutable Games, a global leader in web3 game development and publishing with leading titles Gods Unchained and Guild of Guardians.Our ambition is to make digital worlds real; we have incredible global growth plans as the fastest growing gaming chain in 2024 with 250+ games signed, more than in all previous years combined. 🚀About The Role 🤔As a Protocol Blockchain Engineer at Immutable, you’ll work at the cutting edge of Ethereum scaling and rollup technology. You’ll take ownership of protocol-level features, designing and shipping core blockchain infrastructure that supports high transaction volumes while keeping costs low and latency minimal. You’ll collaborate with world-class engineers to push the boundaries of Layer 2 scalability, interoperability, and performance. Contributing directly to Immutable’s mission of powering the next generation of Web3 games. This role is perfect for someone who thrives in an environment where engineers influence architecture, roadmap, and technology choices, and where deep technical learning is actively encouraged.
You'll Be Empowered To 🎮
- Design, implement, and optimise blockchain protocol components including chain enhancements and cross-rollup bridges.
- Own architectural decisions and set engineering best practices for blockchain development.
- Ensure security, reliability, and performance of protocol changes under high transaction loads.
- Experiment with emerging blockchain technologies such as ZKPs, cross-rollup messaging, and new Ethereum primitives.
- Collaborate across teams to integrate innovations into the Immutable product roadmap.
We’d Love You To Bring 🤝
- Hands-on Ethereum blockchain development experience (smart contracts + protocol-level).
- Proficiency in Solidity and at least one backend language (Golang preferred).
- Strong understanding of distributed systems or large-scale microservices.
- Experience integrating with Ethereum APIs and tooling (JSON-RPC, ethers.js).
- Clear communication skills to explain complex blockchain concepts to both technical and non-technical audiences.
- 5+ years of relevant engineering experience.
- Experience with Layer 2 scaling solutions.
- Deep knowledge of Ethereum Virtual Machine (EVM) internals.
- Familiarity with blockchain bridges or cross-chain communication protocols.
- Contributions to open-source blockchain projects.
- Strong cryptography fundamentals.
Why You’ll Love It Here 💫
- End-to-end impact: from low-level EVM opcode optimisation to user-facing performance gains.
- Ownership and influence: shape architecture and core technology decisions.
- Cutting-edge work: experiment with emerging blockchain primitives and scaling solutions.
- Continuous learning: deep technical challenges, Ethereum ecosystem thought leadership, and innovation-friendly culture.
- Collaborative environment: engineers work side-by-side with product, design, and leadership to deliver meaningful features.
