The engineer will work on optimizing performance and reliability across various services and frameworks.

• 7+ years of experience building and optimizing distributed systems and backend services at scale.
• Deep experience with performance engineering, including profiling and systematic bottleneck analysis.
• Strong understanding of latency engineering concepts and techniques.
• Experience designing and running load tests for high-throughput, latency-sensitive systems.
• Proficiency in Java, Kotlin, or similar JVM languages with a deep understanding of runtime behavior.
• Experience with event-driven architectures and ad serving concepts.

• Profile and optimize the ad serving runtime for latency, throughput, and resource efficiency.
• Identify and eliminate performance bottlenecks across services.
• Design and run load tests and capacity models to validate system behavior under peak traffic.
• Establish performance baselines and implement automated benchmarking in CI/CD.
• Instrument latency telemetry and profiling across the ad request lifecycle.
• Optimize the rule engine framework and frequency management service.
• Drive platform reliability through capacity planning and autoscaling tuning.
• Own performance SLOs and budgets, tracking them and holding teams accountable.
