• Take full ownership of distributed pipeline components from initial design all the way to production, driving quality and reliability at every step.
• Write clean, well-documented code that is  maintainable, extensible, and ready to scale and built for the long haul.
• Work closely with Search Backend, Infrastructure, and partner teams to ensure indexes are fresh, consistent, and delivered on time, every time.
• Dive deep into complex distributed system issues debugging and troubleshooting pipeline failures, index delivery anomalies, and performance bottlenecks across a large-scale, multi-pool infrastructure.

Requirements:

• BS/BA or above in Computer Science or a related field
• 4 or more years of professional software engineering experience building production applications
• Demonstrated ability building backend distributed systems, fault tolerance, consistency, replication, and concurrency
• Deep understanding of data structures, algorithms, and the fundamentals of distributed systems
• Strong proficiency in Java, Scala, or similar languages
• Proven hands-on experience with streaming and data pipeline technologies -  Kafka, Spark, Flink, or similar
• Experience with cluster coordination tools like Zookeeper
