Systems Engineer

About the role

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

• We're looking for an engineer experienced in building robust, high-performance systems who is excited about solving hard infrastructure problems. You'll work on distributed execution systems with strict correctness and performance requirements.
• Architect high-performance systems and leverage AI to implement them in Rust.
• Build and optimize 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, synchronization, 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.
• Equal Opportunity Employer
