Collaborate with platform engineers and SREs to create scalable, resilient search infrastructure that helps merchants succeed at the infinite game of entrepreneurship.

Key Responsibilities:

• Build high-throughput scatter-gather systems that coordinate queries across hundreds of shards and aggregate results efficiently.
• Own search APIs end-to-end—interface design, load balancing, circuit breaking, and graceful degradation.
• Optimize networking and JVM performance—connection pooling, request batching, GC tuning, and profiling for high-load scenarios.
• Design comprehensive observability through structured logging, metrics, and distributed tracing.
• Build A/B testing frameworks enabling data-driven experimentation at scale.
• Solve distributed systems challenges—consistency, availability, latency tail tolerance, and failure handling.

Qualifications:

• Proven expertise in Java for building production distributed systems at scale.
• Experience with search infrastructure, particularly scatter-gather patterns and distributed query execution.
• Networking expertise—HTTP/2, TCP tuning, connection management, protocol design.
• Experience with service frameworks—Thrift, gRPC, or similar RPC frameworks.
• Observability expertise—building logging pipelines, metrics infrastructure, distributed tracing.
• Load balancing and A/B testing experience—consistent hashing, adaptive routing, experiment design.
• Strong collaboration skills, working with cross-disciplinary teams including platform engineers and data scientists.
