• Build and optimize high-throughput applications using Postgres, Kafka, and Redis/Redis Pub Sub, prioritizing data integrity and low latency.

• 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.

Qualifications

• 3 plus years of software engineering experience with a primary focus on distributed systems and high-concurrency environments.

• Expert-level proficiency in Java or Kotlin, Spring Boot, and modern API design (REST, gRPC, and Protobuf).

• Deep experience with Kafka (or Red Panda/Pub Sub), 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.

• B.S., M.S., or PhD in Computer Science or equivalent professional experience.
