Principal Software Engineer

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 in Kafka, 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
