Site Reliability Engineer

• As a Site Reliability Engineer (SRE) at Polygon Labs, you will play a key role in helping operate and support the production infrastructure that powers the Polygon network. Working alongside experienced SREs and protocol engineers, you will gain hands-on exposure to running large-scale, distributed blockchain systems while learning best practices for reliability, observability, and incident response. • This is an ideal role for someone early in their SRE or infrastructure career who is curious about how production systems work, motivated to learn through real-world operational challenges, and excited to grow within a collaborative and mentorship-driven environment. Your work will directly contribute to the reliability and performance of critical public infrastructure used by developers and users globally. • Monitoring production systems, alerts, dashboards, and logs across Polygon networks, including Polygon PoS and the Agglayer. • Assisting with incident detection, triage, escalation, and resolution under the guidance of senior engineers. • Supporting on-call and operational coverage through structured rotations, with training and mentorship. • Following, maintaining, and improving runbooks and standard operating procedures. • Assisting with routine operational tasks such as service restarts, upgrades, and configuration changes. • Helping maintain and improve monitoring, logging, and alerting systems, including dashboards for network health, RPC performance, and node metrics. • Learning to improve alert signal quality and reduce operational noise. • Supporting cloud-based and containerized infrastructure, including nodes, RPC endpoints, and supporting services. • Collaborating with protocol, product, and cross-functional teams to understand production issues and user impact. • Participating in post-incident reviews and contributing to root-cause analysis documentation. • Continuously building knowledge of blockchain fundamentals, distributed systems, and networking.
