Blockchain Engineer
About the Role
As a Blockchain Engineer at Immutable, you will work at the cutting edge of Ethereum scaling and rollup technology. You will 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 will collaborate with world-class engineers to push the boundaries of Layer 2 scalability, interoperability, and performance, contributing directly to powering the next generation of Web3 games. This role is perfect for you if you thrive in an environment where engineers influence architecture, roadmap, and technology choices, and where deep technical learning is actively encouraged.
