Senior Data Scientist Payments Infrastructure

We are building the connectivity layer that powers digital payments across the worlds largest wallet network already embedded in platforms serving tens of millions of users across 120 countries. As we scale our payments data is becoming foundational to everything we do. This is the moment we move from MVP pipelines to production-grade architecture and we need a senior engineer to help build it.

The Role

Youll design and operate the data platform behind a real-time high-volume global payments network. Working closely with the Data Engineering Lead youll build event-driven pipelines ensure data quality across critical financial workflows and develop backend services that expose clean reliable data across the business.

What Youll Do

• Design and operate scalable near real-time data pipelines across high-volume transaction flows
• Own data quality monitoring and observability for financial-grade systems
• Model transactional and ledger-style data reconciliation merchant reporting and settlement tracking
• Build backend services that expose data to internal platforms and APIs
• Shape the platform architecture as requirements grow

What You Bring

• 5 years building and operating production data systems
• Strong SQL and Python skills with expertise in large-scale data processing
• Hands-on experience with modern data stack tools Airflow dbt ClickHouse BigQuery Snowflake or similar
• Experience with event-driven real-time or near real-time architectures
• A first-class approach to data correctness reliability and monitoring
• Ability to own systems end-to-end in a remote async environment

Preferred:

• Background in fintech payments or financial data reconciliation settlement or ledger reporting
• Exposure to Web3 blockchain or on-chain data ecosystems
• Rust experience or willingness to learn.

We are particularly interested in engineers who have cut their teeth in demanding fintech or payments ecosystems the kind of environments where data correctness transaction volume and reliability are non-negotiable.

Youll join at a pivotal moment not inheriting a finished platform but helping define one. If youre energised by building data infrastructure that genuinely matters at scale this is your opportunity.
