Job description

The Role

We’re looking for a Data Engineer to join a team building and evolving a modern cloud-based data platform.

This is a hands-on role focused on designing, building, and improving data pipelines and services, while also contributing to API design and occasional frontend work where needed. You’ll work across the stack, primarily in Python and AWS, helping to deliver reliable, well-structured data and making it easier for teams to ingest, access, and use it.

The focus is on practical delivery: building ingestion and transformation pipelines, exposing data through APIs, and supporting a platform that removes bottlenecks and enables better use of data across the organisation.

What You’ll Be Doing

• Design, build, and maintain ETL / ELT pipelines in production environments
• Develop ingestion and egress patterns to support reliable data access and integration
• Work with structured and semi-structured data (e.g. JSON, Parquet)
• Build and maintain data models across a cloud data platform
• Design and implement APIs to expose data for downstream consumers
• Contribute to cloud-based data platform development in AWS
• Support lightweight frontend work (React / TypeScript) for data-focused tools where needed
• Implement observability practices (logging, monitoring, tracing) across data pipelines and APIs
• Improve reliability, performance, and failure handling across the platform
• Collaborate with engineers and analysts to deliver data that supports reporting and operational use cases

What We’re Looking For

• Experience building and supporting data platforms or pipelines in production
• Strong Python skills for data processing, transformation, and pipeline development
• Strong SQL skills, including complex queries and performance optimisation
• Experience with ETL / ELT design and implementation
• Experience working with AWS data services
• Experience working with a cloud data warehouse (e.g. Snowflake, Redshift, or similar)
• Experience designing and implementing APIs
• Strong problem-solving skills and ability to work with evolving requirements
• Good communication skills and experience working in cross-functional teams

Nice to Have

• Experience with TypeScript or JavaScript
• Experience contributing to frontend applications (React)
• Familiarity with observability tooling (logging, monitoring, tracing)
• Experience with data modelling and metadata management
• Exposure to CI/CD practices for data pipelines and services
• Experience working in delivery-focused, agile environments

Please note:

We offer flexible hybrid working, but candidates should be based in Northern Ireland and able to attend our Belfast office when required.
