Responsibilities

  • Assess current communication technologies, patterns, recurring problems, and capability gaps across engineering teams.
  • Define evaluation criteria and use load tests and benchmarks under representative traffic and failure conditions to select and maintain a Core Collection of recommended communication technologies, patterns, and practices.
  • Document recommended technologies, valid alternatives, and exceptional cases through decision guides, reference architectures, architecture decision records (ADRs), and tuning and troubleshooting guides.
  • Build and maintain validated reference implementations, starter templates, and shared libraries for common communication use cases.
  • Guide the choice between synchronous request/response, asynchronous messaging, event streaming, and other communication patterns.
  • Establish practices for delivery guarantees, ordering, retries, deduplication, and idempotency.
  • Guide backpressure, buffering, batching, flow control, and consumer concurrency design.
  • Optimize throughput, latency, serialization overhead, network utilization, and memory pressure.
  • Establish practices for message schemas, data contracts, and backward- and forward-compatible schema evolution.
  • Guide partitioning, fan-out, replay, retention, and consumer-group design.
  • Establish practices for fault handling, dead-letter processing, observability, and recovery.
  • Partner with engineers through pair programming, design and code reviews, troubleshooting, and focused workshops to support consistent adoption of recommended practices.
  • Collaborate with Data Storage and Deployment Environments domain leads on cross-domain problems such as consumer lag, memory pressure, distributed tracing, and end-to-end throughput and latency.
  • Periodically reassess and update recommendations and documentation as technologies, workloads, and engineering needs change.
