If you want to work in an environment where you can learn, grow, be an agent of change, and have your voice heard — please read on. About the Role As a Support Engineer — China , you will be the front-line technical owner for some of our largest enterprise customers in China deploying ClickHouse on Alibaba Cloud. This is a hands-on, customer-facing role that sits at the intersection of database engineering and operations — closer in spirit to a senior DBA than a traditional helpdesk role. You will deliver excellent customer service as a representative of ClickHouse, providing professional response and guidance within the required Service Level Agreement (SLA) on technical cases opened via our ticketing system, email, IM, and/or phone. You will build strong, trusted relationships with customers, partners, and colleagues across our global Engineering, Cloud, and Core Database teams. What You Will Do Own the full lifecycle of customer issues for ClickHouse strategic accounts on Alibaba Cloud in the China region — from intake and reproduction through to root-cause analysis, resolution, and post-incident follow-up. Triage, classify, and track incoming cases; identify recurring patterns across customers and feed them back into knowledge base articles, runbooks, and product feedback for our Core, Cloud, and Engineering teams. Diagnose and resolve issues spanning SQL and query performance, schema and table-engine design, replication and sharding, ingestion pipelines, materialized views, resource utilization, and cluster operations. Advise customers on ClickHouse best practices, capacity planning, and configuration tuning for workloads running on cloud infrastructure. Escalate complex or product-level issues through the appropriate channels to our global Core Database and Cloud Engineering teams, while remaining the single point of contact for the customer until resolution. Partner with the China Engineering Manager and the global Support organization to define SLAs, on-call rotations, and escalation paths suited to the China region. Contribute to internal tooling, documentation (in both English and Chinese where helpful), and the broader ClickHouse community.
