• Drive performance across services and infrastructure, implementing strategies for backpressure, circuit breaking, and "Exactly-Once" processing.
• Partner with product and engineering leadership to align technical strategy with business goals, making "big bet" decisions on build vs. buy.
• Foster a mindset of well-designed systems and test-driven development. Lead deep-dive code reviews, maintain technical documentation, and mentor engineers.
• Set company-wide standards for observability, schema evolution, and deployment patterns within a cloud-native environment.

• Expert-level proficiency in Java or Kotlin, Spring Boot, and modern API design (REST, gRPC, and Protobuf).
• Deep experience with Kafka (or Red Panda/PubSub), including an understanding of internal mechanics, partition strategies, and consumer group rebalancing.
• Hands-on experience with Kubernetes, Helm, Terraform, and cloud-native infrastructure.
• Proven ability to diagnose bottlenecks in asynchronous messaging and implement complex architectural patterns like idempotency and distributed caching.
• Demonstrated ability to influence technical direction without direct authority and guide teams through complex architectural transitions.
