Manager, Site Reliability Engineering

Description

LayerZero

The Future is Omnichain.

Founded in 2021, LayerZero’s vision is to create a community of cross-chain developers, building dApps that are no longer constrained by individual blockchain capabilities. With LayerZero's simple, generic messaging protocol, builders will develop cross-chain dApps designed to unify the power of individual blockchains.

We are funded by the best investors in the world including:

a16z, Sequoia, PayPal, Binance Ventures, Coinbase Ventures, Uniswap Labs, Circle Ventures, Delphi Digital, and many more.

ABOUT THE ROLE

At LayerZero, our Site Reliability Engineering (SRE) team is at the intersection of software and systems engineering, dedicated to crafting and maintaining large-scale, resilient systems. Our goal is to ensure that all LayerZero services — ranging from critical internal systems to those external users interact with — are reliable, meet the uptime expectations of our users, and continuously evolve at a swift pace. Our SRE professionals will monitor our system's capacity and performance to uphold these standards.

As Manager of SRE, you'll lead a team of engineers responsible for the reliability, performance, and scalability of our blockchain node infrastructure and platform services — while staying technically sharp enough to guide architecture decisions and jump into critical incidents. You'll balance people leadership with hands-on technical judgment, shaping how the team works, grows, and scales alongside LayerZero.

Responsibilities

• Lead and develop a team of SREs — setting technical direction, growth plans, and performance expectations.
• Own the reliability strategy for blockchain node infrastructure across a variety of DLTs, including SLOs, capacity planning, and incident response.
• Partner with Engineering leadership and Product/Platform teams to align reliability investments with business priorities.
• Drive infrastructure-as-code practices, with a focus on Kubernetes and Helm at scale.
• Establish and continuously improve on-call structure, incident detection/triage automation, and postmortem culture.
• Stay hands-on: review designs, dig into complex incidents, and set the technical bar for the team.

Requirements

• Bachelor's degree in Computer Science, similar technical field of study, or equivalent practical experience.
• 6+ years in SRE, DevOps, or infrastructure engineering, including 2+ years directly managing or leading a technical team.
• Deep familiarity with blockchain node infrastructure (validator/full/archive nodes, RPC optimization, etc.).
• Strong proficiency in TypeScript or Golang, with the judgment to know when to write code vs. delegate.
• Advanced knowledge of Unix/Linux internals and distributed systems / high-availability design.
• 3+ years running Kubernetes in production, including Helm chart authoring at scale.
• Track record building or scaling an on-call/incident response process.
• Excellent communication skills — able to represent the team to leadership and hire/retain strong engineers.
