Job Description
Wise is looking for a Senior Software Engineer II to join the Data Onboarding Team stationed in London. This full-time, on-site role focuses on building, scaling, and optimizing critical data pipelines on top of the company's Lakehouse infrastructure to support global financial processes. Wise aims to build borderless money movement that is fast, transparent, and eventually free, and this engineering position acts as a fundamental pillar for financial reporting and assurance across the organization.
The person in this role will abstract product complexity to construct reusable, domain-agnostic stream-enrichment pipelines handling hundreds of millions of high-throughput financial events daily. Responsibilities include implementing a strict Medallion Architecture with Bronze, Silver, and Gold layers, establishing automated data quality checks, and collaborating closely with finance controllers, analysts, product teams, and engineering peers. The role also involves providing technical mentorship and code reviews for junior and mid-level team members.
This position is suited for an experienced data engineer who has a strong command of modern Lakehouse stacks, streaming architectures, and advanced data modeling. The successful candidate will enjoy taking long-term technical ownership and bridging the gap between engineering implementations and corporate finance requirements within a regulated fintech environment.
Responsibilities
- Design, build, and optimize end-to-end data pipelines utilizing Trino and Apache Iceberg Lakehouse technologies
- Implement Medallion Architecture layers to refine raw event logs into verified subledgers and structured Gold metrics
- Manage stream processing workflows with Kafka to sustain strict data freshness service level agreements
- Embed automated reconciliation and validation checks into pipelines to catch data errors before financial reporting
- Partner with finance controllers, analysts, and product engineers to translate corporate finance needs into production-ready schemas
- Optimize compute infrastructure and address scaling constraints to align with financial targets
- Mentor junior and mid-level engineers by performing technical design and code reviews
Requirements
- Proven experience building data infrastructure using Trino or Presto and open table formats like Apache Iceberg or Delta Lake
- Deep expertise in Medallion Architecture patterns, Star Schemas, and processing semi-structured financial logs in JSON or Avro formats
- Expert proficiency in data transformation engines such as dbt and scheduling tools like Airflow
- Solid understanding of event-driven architectures and stream processing via Apache Kafka
- Strong programming foundations in Python, SQL, or an Object-Oriented language such as Java or Scala
Qualifications
- Experience operating data assets within a regulated SOX or PCAOB compliance environment
- Familiarity with cloud data warehouses like Snowflake and cloud compute orchestration
- Prior domain exposure to financial flows, double-entry ledger systems, or accounting integrations
