Job summary

BILL is seeking a senior Data Platform Engineer to own the core data infrastructure and steer platform capabilities end-to-end. You will shape architectural direction, drive cross-team data initiatives, and partner with ML/AI, Risk, Payments, and Analytics to deliver durable solutions.

You will lead multi-phase migrations, enforce standards, and mentor engineers while ensuring reliable, cost-efficient data services for BILL's growing fintech ecosystem.

Qualifications

• Bachelor's degree in Computer Science, Engineering, Mathematics, or equivalent work experience.
• 8+ years of experience in data engineering, distributed systems, or software engineering with a heavy focus on data infrastructure.
• 5+ years of experience specifically on data platform, data infrastructure, or data systems teams.
• Expertise in distributed systems design for data workloads, including streaming, batch, and real-time serving trade-offs.
• Hands-on experience with event streaming platforms (Kafka, Flink, Spark Streaming, or equivalent) and CDC-based ingestion patterns.
• Strong proficiency with batch processing stacks (Airflow, dbt, Spark/Glue, or equivalent).
• Experience with modern open table formats and data lake architectures, including Apache Iceberg, Delta Lake, or equivalent frameworks.
• Familiarity with data access and serving layers, including query engines (Trino/Starburst, Presto), feature stores, vector stores, or graph databases.
• Expert-level SQL and strong Python skills, backed by solid software engineering fundamentals such as CI/CD, testing, and observability.
• Demonstrated experience architecting and operating large-scale, production-grade data platforms.
• A proven track record operating as a technical lead, with the ability to drive ambiguous, high-impact projects from first principles to production.
• The ability to define technical standards that hold across organizational boundaries rather than just within a single team.

Responsibilities

• Operate at the architectural level, driving platform-wide technical decisions and mentoring the team.
• Own and evolve critical infrastructure across the full data lifecycle, spanning ingest, store, enrich, query, and serve.
• Architect and own critical data platform capabilities end-to-end, from inbound ingestion through data lake storage to downstream serving, including the feature store, query engine, knowledge graph, and search.
• Define technical direction for the team’s most complex, cross-cutting problems, such as streaming versus batch trade-offs, schema contracts, data access patterns, and real-time serving architectures.
• Drive design and delivery of new capabilities from inception to GA, including reference implementations, SLAs, and clear ownership handoff models.
• Establish and maintain architectural standards and engineering patterns adopted across the organization.
• Lead multi-phase technical migrations at enterprise scale, including compute platform upgrades, warehouse-to-lake migrations, and infrastructure modernization.
• Partner with engineering teams across BILL, such as ML/AI, Risk, Payments, and Analytics, to translate diverse data needs into durable platform solutions.
• Mentor senior and staff engineers, actively shaping the technical culture and engineering quality bar of the team.
• Own and continuously improve critical production systems with a focus on reliability, cost efficiency, and a self-serve developer experience.
