## Description

We're seeking a Systems Engineer to join LayerZero.

In this role, you'll build the foundational systems that power our execution and infrastructure layers, including Zero.

This is a low-level, performance-critical role focused on runtime architecture, concurrency, and scalable execution.

You will make architectural decisions that directly impact how our systems execute, scale, and remain stable under load.

Responsibilities:

- Architect high-performance systems and leverage AI to implement them in Rust.

- Build and optimise core runtime, networking, or state management components.

- Profile and improve performance both at low-level (CPU, memory) and cluster-scale (network, scheduling).

- Debug race conditions, deadlocks, and production performance issues.

- Contribute to architectural decisions around scheduling, synchronisation, and system scalability.

- Own systems end-to-end from design through production.

About You:

- Bachelor's degree in Computer Science, Computer Engineering, or equivalent practical experience.

- 2+ years of experience building systems-level or performance-critical software.

- Strong proficiency in systems programming and leveraging AI to build software.

- Deep understanding of concurrency, CPU architecture, cache hierarchy, and operating systems.

- Experience designing or contributing to low-level storage, compute, or network infrastructure.

- Strong intuition for striking a pragmatic balance between complexity for performance and simplicity for robustness.

- Experience using low-level profiling and debugging tools in production environments.

- Interest in working on distributed and execution-layer systems.
