About the Role 

This is a Lead Developer role with a strong focus on performance engineering. You will spend your time building and optimizing high-throughput, low-latency systems at scale — writing production Java code, hunting down bottlenecks, and making the platform faster and more resilient. 

Performance is the through-line of everything you do: you'll set performance requirements, design and execute the testing that validates them, profile and tune the system end-to-end, and build the engineering practices that keep it fast release over release. You'll work on services built on Kafka, MongoDB, Elasticsearch, Debezium, and Spring Boot running on AWS. 

The “lead” in this role is technical, not managerial. You lead through hands-on work, strong engineering judgment, and by raising the performance bar for the people around you — through design and code reviews, mentoring, and setting standards — while remaining a core contributor in the codebase.
