Qualifications

• Proven experience building large-scale backend or data systems where reliability, throughput, latency, scalability, and cost are important considerations.
• Demonstrated ability to take systems from concept to production, including scoping, architecture, implementation, release, operation, measurement, and continuous improvement.
• Strong knowledge of distributed systems and ability to reason about partial failures, retries, idempotency, backpressure, scaling, fault tolerance, and operational tradeoffs.

• Design and maintain systems that determine which creators to collect, when, and how frequently, balancing value and cost.
• Own backend systems lifecycle from requirements to deployment and operation.
• Build observability, alerting, monitoring, and safeguards to detect failures and data-quality issues.
• Collaborate with data, search, product, and engineering teams to establish reliable interfaces and dependencies.
• Evaluate approaches through production experiments focusing on throughput, scalability, and unit economics before large investments.
