Senior Data Engineer.

Department: Product Development

Location: Ireland (Dublin)

Employment Type: Full-Time, Permanent

Reports to: VP of Engineering

Work Model: Hybrid, 3 days per week in the Dublin office

Senior Data Engineers own the department's data integration and analytics platform, modelling data with SQL Transformation Layer on Amazon Redshift, curating the QuickSight / SPICE presentation layer, and integrating external sources such as Salesforce into the central data warehouse. They also make the warehouse and its semantic layer AI-ready, well-modelled, documented and governed so GenAI tooling (e.g. natural-language-to-SQL on AWS Bedrock) and downstream AI features can consume trusted data safely.

Key Objective / Role

Lead the design and delivery of data-enablement solutions on the AWS ecosystem, liaising with internal and external stakeholders to define and ship high-quality data pipelines that power our reporting and analytical capabilities. Own the Redshift warehouse, the RapidRatings ELT service and orchestration, the QuickSight semantic and reporting layer, observability and production data quality on business-critical marts, increasingly designing data products that power AI-native and internal GenAI tooling, in line with our AI-Driven Development Lifecycle (AI-DLC) delivery model.

Key Working Relationships

• Product, Business and Operations stakeholders, requirements, data-quality reporting and sign-off.
• Platform & Application engineering squads, AI / ML and platform initiatives such as Bedrock / GenAI tooling, semantic-layer definition and AI data-governance.
• QA and external data providers for integration and end-to-end testing of data deliverables.

Essential Duties and Responsibilities 

• Design & operate the data warehouse and ELT: build, run and operate the AWS data warehouse and analytics environment; develop and maintain our SQL Transformation Layer on models across staging → intermediate → mart layers (incremental models, tests, auto-generated docs); integrate new external sources in and move curated data out to applications and affiliates, using GenAI to accelerate model/test generation under human review and CI guardrails.
• Run the AWS analytics stack: operate Glue Data Catalog, S3 / Athena, Redshift and the QuickSight / SPICE presentation layer; build reports and visualisations; and manage performance and cost through retention / cold-archiving policies and query-performance tuning.
• Orchestrate & observe pipelines: schedule, orchestrate and monitor batch / ELT jobs; manage job dependencies, failures and end-to-end pipeline observability.
• Own production data quality: monitor and remediate mart-refresh and reconciliation defects on business-critical marts, and report data-quality status to product and business.
• Apply governance, privacy & security controls: implement best-in-class security alongside PII anonymisation, right-to-erasure (member deletion / archival), dashboard-export restrictions and QuickSight group / permission management (RBAC).
• Build the semantic / metrics layer: maintain the semantic layer and curated, documented datasets that serve as trusted context for GenAI tooling and downstream AI features.
• Deliver AI-native data capabilities: deliver and operate natural-language-to-SQL / analytics-assistant capabilities on AWS Bedrock (RAG over warehouse metadata and lineage) with evaluation, guardrails, monitoring and cost controls (accuracy, hallucination and PII / data-leakage safeguards); and prepare feature-ready datasets and embeddings / vector stores that keep outputs explainable and auditable.
• Mentor & collaborate: help engineers across the department troubleshoot SQL, Python and AI, acting as a strong technical collaborator who raises the team's overall data-engineering capability.

Key Competencies

• SQL, data modelling & data warehousing: deep SQL and dimensional / data-warehousing expertise, with proven ETL/DWH delivery of end-to-end data integration for large-scale warehouses.
• SQL Transformation & modern ELT modelling: hands-on SQL and modern ELT / warehouse modelling (dimensional and medallion-style layering).
• AWS data stack: strong across Glue, S3, Athena, Redshift / PostgreSQL and QuickSight.
• Orchestration, observability & data quality: pipeline orchestration, scheduling and observability, with ownership of production data quality, defect resolution and the maintenance of systems, processes, code and pipelines across varied sources and types.
• Data management & quality frameworks: Data Quality Profiling, Metadata Management, Master Data Management and cleansing / standardising, with strong general data-manipulation skills (clean, transform, recode, merge and reshape).
• Data visualisation: experience with visualisation tools (QuickSight, Power BI, Yellowfin), including advanced data visualisation and mapping.
• Data governance, PII & RBAC: governance, PII handling and role-based access control in a regulated member-data environment.
• GenAI / LLM for analytics: working knowledge of GenAI / LLM services (e.g. AWS Bedrock), prompt engineering, RAG and vector / embedding stores, and how to structure semantic / metrics layers so AI can query data reliably.
