Job Description

Data Engineer
We're looking for a Data Engineer with strong Python skills and experience in event-driven systems to join our growing data team. This isn't your typical "pipelines-for-analysts" role -you'll be building real-time systems that power applications, tooling, and commercial products across the business.
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.
