About The Opportunity

We are building the foundational data infrastructure that powers one of the world's leading crypto exchanges. As a Big Data Platform Engineer , you will design, build, and evolve the core platform services that enable hundreds of data engineers and analysts to move fast and ship reliable pipelines. You will be at the forefront of our AI agent initiative — embedding LLM-driven capabilities directly into the platform layer so that scheduling, cost optimization, and incident response increasingly run autonomously.

What You’ll Be Doing

• Platform Core: Design and operate large-scale distributed data systems

• Own the big data compute and storage infrastructure (MaxCompute/ODPS, Hologres, Spark)

• Build and maintain multi-site task orchestration that dynamically selects engines and enforces policy

• Drive reliability and performance improvements across batch and real-time pipelines

• AI Integration: Build the AI-native platform layer

• Develop and expose MCP (Model Context Protocol) tool interfaces so AI agents can interact with platform APIs

• Build the scheduling and cost-optimization agents that auto-tune resource allocation and alert severity

• Instrument platform telemetry to feed AI-driven SLA monitoring and anomaly detection

• Design context retrieval pipelines (RAG / vector search) for SQL code and config knowledge bases
