Responsibilities
Design and develop complex workflows and activities using Temporal, leveraging features such as retry policies, saga patterns, child workflows, signals, and queries.
Implement workflows with state persistence, ensuring recoverability, consistency, and reliability in distributed environments.
Optimize workflows for performance, fault tolerance, and low-latency execution.
Handle long-running processes effectively, managing timeouts, scheduled tasks, and compensations.
Architect workflows with robust resilience patterns, including retry with backoff, dead-letter queues, and idempotency handling.
Ensure reliable message processing in distributed environments using tools like AWS SQS, SNS, EventBridge, or Kafka.
Design for at-least-once and exactly-once processing semantics to ensure workflow consistency.
Implement circuit breakers, load shedding, and backpressure handling to maintain system stability under load.
Develop scalable, fault-tolerant systems with a focus on high-throughput workflows and dynamic task scheduling.
Design for efficient parallel task execution, fan-out/fan-in patterns, and event-driven architectures.
Build systems that handle graceful degradation, ensuring minimal disruption during failures.
Implement monitoring and alerting for workflows and systems using tools like Temporal Web UI, Prometheus, Grafana, and AWS CloudWatch.
Set up observability for workflow state transitions, latency metrics, and error patterns to proactively identify and resolve issues.
Design robust fallout management systems, including automated retries, compensating transactions, and manual intervention mechanisms when necessary.
Work with cross-functional teams to integrate workflows seamlessly into broader system architectures.
Establish and promote best practices for workflow automation, resilience patterns, and distributed system performance.
Mentor and guide team members in Temporal concepts, workflow patterns, and resilient design principles.
