Requirements

• Proven experience building data infrastructure using Trino / Presto and open table formats like Apache Iceberg or Delta Lake.
• Deep expertise in Medallion Architecture patterns, Star Schemas, and processing semi-structured financial data logs (JSON/Avro).
• Expert proficiency in data transformation engines (such as dbt) and scheduling tools (such as Airflow).
• Solid understanding of event-driven architectures and streaming processing via Apache Kafka.
• Proficiency in Python, SQL, or an Object-Oriented language (Java/Scala).

Nice to Haves

• Experience operating data assets within a regulated SOX/PCAOB compliance environment.
• Familiarity with cloud data warehouses (e.g., Snowflake) and cloud compute orchestration.
• Prior domain exposure to financial flows, double-entry ledger systems, or accounting integrations.

What you'll be doing

• Design, build, and optimize robust end-to-end data pipelines on the Trino + Iceberg Lakehouse stack.
• Own extraction, cleaning, and modeling layers to refine raw event logs (Bronze) into verified subledgers (Silver) and structured Gold metrics.
• Work closely with high-throughput messaging queues (Kafka) and real-time computation models to maintain data freshness SLAs.
• Embed rigorous, automated reconciliation checks within data pipelines to detect data discrepancies before financial reporting.
• Partner with finance controllers, analysts, product, and engineering teams to convert complex finance needs into production-ready data schemas.
• Address data scaling, technical debt, and compute optimizations to align infrastructure costs with financial targets.
• Mentor and coach mid-level and junior engineers, including performing code and technical design reviews.

Perks and Benefits

• Starting salary: £111k - £145k + RSUs.
• Opportunity to help engineer the core "Engine of Trust" for a fast-growing global fintech.
• Chance to build reusable libraries and system-wide framework layers instead of bespoke solutions.
• Direct collaboration with top-tier product minds, data platform engineers, and global financial stakeholders.
• Access to Wise Benefits.
