Senior / Staff Java Engineer Core Infrastructure & Site Reliability (Java)
What you'll be doing You'll identify systemic risks across the platform's core services and lead the infrastructure work to close them — end-to-end performance, reliability, and architecture, not just individual features. You'll drive infrastructure optimization and platform-level solutioning that scales across multiple product lines, and continuously evaluate new tools, patterns, and technologies to strengthen the stability framework long-term. Code review and hands-on engineering leadership are core to the role, not an afterthought.
What we're looking for 8+ years of hands-on development and architecture experience, ideally with progression into a senior or staff-level ownership role. Strong recent experience in Java (Spring Boot) — Go or C++ background also considered. Solid computer science fundamentals and a real understanding of SRE/DevOps principles — this is not a 'basic scripting' DevOps ask, it's core to the role. Hands-on depth across the modern backend stack: Nginx, Redis, ElasticSearch, Kafka, MySQL, Docker, Kubernetes. A track record of designing systems from scratch and rationalizing architecture for new business lines — not just maintaining what already exists. JVM troubleshooting/performance optimization experience is a strong plus. Fluent in English and Mandarin — this team works closely with cross-functional and international stakeholders. Background from major internet/tech platforms (Chinese or global Big Tech) or crypto-native companies is highly relevant.
