Job description

Responsibilities

• ●Architect and implement the core routing and query execution engine for the data fabric platform
• ●Develop robust connection management infrastructure spanning heterogeneous data stores (Kafka, MySQL, Flink, Delta/Iceberg)
• ●Engineer end-to-end request pipelines optimized for P99 latency targets and high-throughput requirements
• ●Design and implement fault-tolerant systems including error handling, retry mechanisms, and circuit breaker patterns
• ●Establish comprehensive observability framework incorporating structured logging, distributed tracing, and metrics collection
• ●Drive API design decisions and define service contracts in collaboration with cross-functional stakeholders

Requirements

• ●Minimum 3 years of professional experience developing low-latency, high-throughput services using C++, Go, or Rust in production environments
• ●Demonstrated expertise in concurrency patterns, asynchronous I/O, connection pool management, and backpressure handling mechanisms
• ●Production-level experience with inKafka, MySQL, Apache Flink, Delta Lake/Iceberg
• ●Proven track record optimizing systems for low-latency requirements (P99 < 100ms) and high throughput, including profiling and systematic bottleneck resolution
• ●Extensive experience designing and implementing services using gRPC, Protocol Buffers, or equivalent RPC frameworks at scale
• ●Demonstrated experience deploying and operating services managing 100K+ concurrent connections with comprehensive observability infrastructure

Preferred Requirements

• ●Experience with query parsing, optimization, and abstract syntax tree (AST) manipulation
• ●Implementation experience with adaptive rate limiting or circuit breaker patterns
• ●Knowledge of zero-copy techniques, memory-mapped I/O, or other advanced performance optimization strategies
• ●Background in stream processing frameworks and real-time data pipeline architectures
