Circle is a financial technology company at the epicenter of the emerging internet of money, where value can finally travel like other digital data — globally, nearly instantly and less expensively than legacy settlement systems. This ground-breaking new internet layer opens up previously unimaginable possibilities for payments, commerce and markets that can help raise global economic prosperity and enhance inclusion. Our infrastructure – including USDC, a blockchain-based dollar – helps businesses, institutions and developers harness these breakthroughs and capitalize on this major turning point in the evolution of money and technology.

We have built a flexible and diverse work environment where new ideas are encouraged and everyone is a stakeholder.

What You’ll Be Responsible For

As a member of the Data Platform Engineering team, you own the core Data / ML platform, including data ingestion and processing (with a focus on both traditional and blockchain data ingestion), ETL / ELT pipelines, data governance and security compliance, data analytics and visualization tooling, data modeling, and warehousing. You will also help build systems for monitoring data pipelines and onchain activity to ensure reliability and observability. These components power our Product, Engineering, Analytics, and Data Science teams by enabling experimentation, operational excellence, and actionable insights to accelerate business growth.

What You’ll Work On

• Design, build, and operate data platform services such as warehousing, orchestration, data catalogs, and ingestion frameworks.
• Develop and maintain scalable ingestion pipelines, including onchain / blockchain data ingestion, with robust handling of node APIs, rate limiting, and data consistency.
• Implement data alerting mechanisms to monitor critical events or anomalies in ingested data (e.g., specific onchain transactions, contract changes, or volume spikes).
• Handle ingestion pipelines that operate across a broad range of scales, from small partner datasets to high-throughput blockchain transaction streams.
• Continuously improve platform operations through better monitoring, performance tuning, reliability enhancements, and resource optimization.
• Collaborate across Product, Engineering, Data Science, Security, and Compliance teams to establish data contracts, governance, and lifecycle management.
• Serve as a domain expert in data warehousing, data modeling, pipeline orchestration, and ensuring data quality at scale.
• Provide ML / AI platform capabilities for data scientists to run experiments, manage training data, and perform feature engineering.
• Build and maintain foundational services such as data asset cataloging and lineage tracking, data versioning and quality metrics, auto-backfilling for incomplete data scenarios, and fine-grained access control on datasets.

What You’ll Bring To Circle

• 2+ years of experience in software engineering, preferably focused on data systems.
• Familiarity with building or maintaining scalable data infrastructure for batch, micro-batch, or streaming pipelines.
• Exposure to business domains such as payments, banking, or blockchains is a plus.
• Understanding of data governance concepts like data lineage, quality, and access control.
• Interest in open-source data tools and technologies.
• Comfortable working through technical problems, even when requirements are not fully defined.
• Proactive, curious, and eager to learn and contribute in a fast-paced environment.
• Good communication skills and ability to collaborate with team members across functions and locations.
