• Find performance bottlenecks and design systems that can support significant growth.
• Improve low-latency APIs and build caching layers to meet performance goals.
• Extend multi-cloud and multi-region infrastructure to support global data residency requirements.
• Work with customers on scaling challenges and contribute to system reliability.

What We're Looking For

• 7 or more years of backend software engineering experience, with deep distributed systems expertise.
• Experience building event collection, data streaming, or data syncing systems for critical services, ideally at terabyte scale.
• Production experience with Kafka, SQL databases, Kubernetes, and Docker.
• Strong systems design fundamentals and familiarity with the internals of streaming and batch frameworks such as Spark and Flink.
• A track record of owning systems through substantial growth, ideally in a high-velocity startup environment.
