What you’ll be doing:
-Build and maintain event-driven data pipelines that power Citywire’s Catalyst platform.
-Design resilient, fault-tolerant workflows using AWS services such as Lambda, Kinesis, SQS, DynamoDB Streams, and EventBridge.
-Implement processors that ensure data consistency across DynamoDB, PostgreSQL (Aurora), OpenSearch, and BigQuery.
-Modernise legacy batch processes into stream-first architectures.
-Build and integrate APIs to enable smooth publishing and consumption of events across systems.
-Collaborate with engineers on greenfield and existing projects, balancing speed with resilience.
-Take ownership of key pipelines and services, ensuring reliability, performance, and scalability.
-Share best practices and mentor others in event-driven data engineering.
What we’re looking for:
-Technical Skills: Proven experience in data engineering or backend development, with solid Python skills and hands-on use of AWS event-driven services.
-Event-Driven Knowledge: Understanding of DLQs, retries, buffering, idempotency, and resilient design patterns.
-Cloud & CI/CD Experience: Familiarity with Terraform, Git-based workflows, and cloud-native deployments.
-Database Skills: Experience with SQL and NoSQL databases such as PostgreSQL, DynamoDB, or OpenSearch.
-Problem-Solver: Comfortable working in Linux environments and confident debugging logs, scripts, and production issues.
-Additional Skills: Exposure to Kafka, Spark, or dbt Core, with an interest in domain-driven data contracts.
