Data Engineer

About the role

• As a Data Engineer, you’ll build and own the data foundation behind CYBERA’s mule intelligence and scam prevention products. You will turn high-volume, messy operational data into fast, reliable, and trusted datasets that our analysts, products, and customers can use with confidence. Working closely with engineering and data analytics, you’ll own the data warehouse and lake, strengthen data quality and performance, and create scalable standards for modelling, lineage, and metric definitions. This is a hands-on role on a small team where you will have significant ownership and the agency to solve problems end to end.
  
  

What you'll do

• Own our data warehouse and data lake end to end, from ingestion and storage design through modelling and serving
• Build and operate the pipelines that move data from the CYBERA platform and the systems behind our mule intelligence into the warehouse
• Transform messy operational data into clean, documented datasets that analysts, products, and customer-facing systems can rely on
• Define core business rules and metrics centrally so teams get consistent answers from the same data
• Improve query and platform performance by reviewing execution plans, tuning indexes, and deciding what should be materialized as data volumes grow
• Implement data quality checks, monitoring, and alerting to identify issues before they affect the business or our customers
• Maintain lineage and versioning for data produced by LLM pipelines so changes do not silently alter reported results
• Partner with data analysts on metric definitions, investigate upstream issues, and support reliable dashboards and reporting
• Collaborate with engineers on schema changes, migrations, backfills, and reviews of production data code
  
  

Qualifications

• 4 to 6 years of hands-on data engineering experience, including building or substantially evolving a data warehouse or data lake
• Expert SQL skills and a strong track record of diagnosing and improving slow or complex queries
• Hands-on experience with PostgreSQL, SQL Server, or both
• Deep practical experience with performance tuning, execution plans, indexing, and resolving production slowdowns
• Strong data-modelling fundamentals, including experience designing reliable incremental loads
• Working knowledge of orchestration, transformation, monitoring, and data-testing practices
• Experience applying Git, code review, and continuous integration practices to data code
• A high-ownership mindset and the ability to identify, investigate, and resolve problems in a fast-moving environment

It’s a plus if you have

• Administrative experience with Metabase or another business intelligence platform
• Experience working with LLM or machine-learning data pipelines
• Experience with fraud, fintech, cybersecurity, or other adversarial data
