[Hiring] Support Engineer @ClickHouse

Role Description

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.

Qualifications

• Proven experience in a technical support, DBA, SRE, or database engineering role serving enterprise customers — ideally including on-call and SLA-driven environments.
• Work with Alibaba team and our engineering team to support strategic customer POCs.
• Technical breadth and depth in relevant subjects, for example ClickHouse DBMS or similar, OLAP, Cloud/SaaS platforms, distributed systems software engineering, Linux/Unix, Kubernetes, System or Network Administration, and/or big data and analytics platforms.
• Previous experience operating ClickHouse or other SQL databases in production, with the ability to write and optimize complex SQL.
• Solid Linux fundamentals and comfort debugging production systems: logs, metrics, system calls, network, storage, and performance profiling.
• Working knowledge of distributed database internals — replication, consensus, sharding, consistency trade-offs — and of the operational realities of running them at scale.
• Knowledge of cloud computing platforms such as Alibaba Cloud, AWS, Azure, or Google Cloud Platform.
• Excellent written and verbal communication in both Chinese (Mandarin) and English, with the ability to translate complex technical issues for technical and non-technical audiences.
• A teamwork mindset, customer empathy, and a sense of adventure and urgency in supporting the most scalable, high-performing databases on the planet.
• Self-driven, curious, and eager to continuously learn and grow.

Requirements

• Direct production experience operating ClickHouse clusters at scale.
• Scripting experience with Shell or Python, and the ability to read and understand C++ code.
• Experience with Kubernetes, Terraform, and infrastructure-as-code.
• Familiarity with streaming and data pipeline tools, and modern observability stacks.
• Prior experience supporting strategic accounts, large internet companies, or financial services customers in Greater China.
• Open-source contributions, conference talks, or community involvement around ClickHouse or adjacent projects.
