About the role

Key responsibilities & impact

Build and ship production-quality implementations of the data normalization, schema mapping, validation, enrichment, and distribution pipeline for a net-new intelligent data warehouse
Write clean, well-tested, performant code across the full stack – backend services, data pipeline logic, and API integrations
Take end-to-end ownership of features from design through deployment, with accountability for correctness and reliability in production
Work closely with staff engineers to shape the architecture of a modern, AI-native data warehouse serving institutional financial clients
Bring thoughtful input on schema design, normalization approaches, and API patterns – and execute those decisions with precision
Identify and raise technical risks early; propose and implement solutions rather than waiting to be directed
Use agentic coding tools and LLM-assisted development as your primary workflow – this is how the entire team operates
Critically evaluate AI-generated code for correctness, edge cases, and regressions – shipping quality output regardless of how it was produced
Contribute to the team’s evolving practices around AI-accelerated development and testing
Build and maintain data validation checks, monitoring, and observability tooling that keeps the pipeline trustworthy at scale
Participate in on-call and production support, diagnosing and resolving data quality issues quickly and thoroughly
Write and maintain clear technical documentation for the systems you build
Partner effectively with staff and senior engineers, your engineering manager, and product management to translate requirements into well-scoped, executable work
Participate in design and code reviews, offering and receiving feedback constructively
Develop domain intuition around private markets data – fund administration, investment data schemas, institutional reporting – to make better technical decisions
