Software Engineering (~80%)

• Design, build, and maintain backend services and REST APIs that serve data from various SQL subsystems and other data sources
• Develop well-tested, production-grade Python services with clean API contracts, proper authentication, versioning, and error handling
• Work closely with the Analytics Engineering team to expose modeled data (billing, settlement, finance) through APIs that downstream consumers can rely on
• Build internal tooling and services that enable the broader organization to self-serve their data needs without writing SQL
• Participate in code reviews, system design discussions, and engineering best practices across the Infrastructure org
• Contribute to service observability: logging, metrics, alerting, and on-call practices for the services you own

Data Engineering (~20%)

• Maintain and improve existing data pipelines that move data from source systems into Snowflake (Airflow, Airbyte)
