Data Warehouse Engineer

Join BILL as a Staff Data Warehouse Engineer and help build the trusted data backbone that powers decision-making across Finance, Product and Go-to-Market. You will be a senior technical owner on the Data Operations & Enablement team, designing and delivering end-to-end pipelines and warehouse architecture that become the single source of truth for the business.

• Own end-to-end delivery of pipelines and warehouse architecture, from design through production, for new builds, migrations and re‑platforming efforts.
• Administer and harden the data warehouse, including schema design, performance tuning, stability and cost‑aware optimization.
• Embed data quality and governance into pipelines by default – testing, documentation, lineage – not as an afterthought.
• Translate ambiguous business requirements into clear technical designs; scope trade‑offs and dependencies with cross‑functional stakeholders.
• Define and codify simple, stable, repeatable engineering standards and patterns adopted by the broader team.
• Mentor engineers through design reviews, code reviews and hands‑on guidance to raise the technical bar.
• Evaluate and introduce tools or architecture patterns that materially improve scale, reliability or cost and be able to justify and explain the rationale.
• Design the warehouse to be queried by AI agents, not just people – structure models, naming conventions and metadata so natural‑language querying returns correct results, and author skill files that let AI tools query the warehouse safely and accurately.

• 8+ years of experience in data engineering or combined software/data engineering roles, with a track record of owning significant warehouse builds end-to-end.
• Expert‑level SQL (multiple dialects) and strong Python, with examples of production‑grade applications beyond ad‑hoc scripts.
• Deep knowledge of ETL/ELT design, ingestion methods and orchestration (e.g., dbt, Airflow or equivalents).
• Hands‑on experience with modern lakehouse/warehouse platforms (e.g., Snowflake, Trino/Starburst or similar) and an understanding of engine trade‑offs.
• Experience in financial services and/or SaaS environments.
• Comfort operating with minimal Dev Ops/IT support on core database and warehouse administration.
• Proven mentorship and standards‑setting experience; formal management not required.
