Position Summary We are seeking a Staff Site Reliability Engineer (Official Title: Staff Site Reliability Engineer I) with deep experience operating and evolving large-scale, mission-critical systems where availability and reliability are non-negotiable.

At SHEIN, Site Reliability Engineers are hybrid software and systems engineers responsible for keeping production services always on while enabling the platform to scale rapidly and safely. In this role, you will own and support complex services and infrastructure, ensuring they consistently meet reliability and performance expectations. At the Staff level, you will also provide technical leadership, influencing platform architecture, reliability strategy, and operational standards across the organization.

The SRE team owns and maintains critical open-source and in-house technologies that underpin the platform and serves as a core contributor to major engineering initiatives. We are accountable for driving platform operability forward by reducing incident frequency, minimizing MTTR, and improving system resilience, efficiency, and resource utilization. You will work closely with global, cross-functional teams to design, build, and evolve observability and operational tooling—including metrics, logs, traces, alerting, and automation—providing deep visibility into system behavior.

Through hands-on engineering and operational excellence, you will proactively identify risks and failure modes, help prevent incidents before they occur, and lead fast, effective responses when they do. To succeed in this role, you will combine strong software engineering skills, solid to deep expertise in Linux, networking, and distributed systems, and a passion for solving problems of scale, complexity, and reliability. Your work will directly contribute to delivering a stable, scalable, and high-performing experience for customers worldwide.
