Java Search Infrastructure Engineer

Java Search Infrastructure Engineer

Shopify

Join Shopify's dynamic engineering team, where code is core and innovation drives commerce forward. As a Java Search Infrastructure Engineer, you'll build distributed systems that power search query serving across billions of products. 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.

• Infrastructure engineering

• Infrastructure Engineers at Shopify build and maintain the systems that handle millions of requests per second and billions of dollars in transactions. At that scale, performance gains matter and weak assumptions surface quickly. Your systems power the experience for millions of entrepreneurs and buyers every minute of every day, including peak events like Black Friday.

• Engineers at Shopify spend the majority of their time actually writing code to build and improve infrastructure. You’ll solve problems that don’t exist anywhere else, with challenges that push what’s possible. If that lights you up, come build with us.
