CWILL is building data infrastructure to support business operations, product capabilities, customer service, analytics, and intelligent applications. As a US‑side data engineer, you will participate in multi‑source data ingestion, data lakehouse and warehouse development, data quality governance, data platform capability building, and AI Agent engineering automation exploration.

We are looking for candidates with a solid foundation in SQL, Python, and data engineering — someone who can, with guidance from the existing data team, progressively take ownership of data ingestion, modeling, quality, and service tasks, while collaborating effectively with domestic data engineering, analytics, and business teams.

This is not a pure data analysis, BI reporting, or one‑off scripting role. It is a comprehensive data engineering position focused on data integration, data warehouse development, data platform capabilities, data services, and engineering automation.

Through stable, well‑structured, and scalable data engineering capabilities, help the company unify, govern, model, and serve data scattered across business systems, SaaS platforms, external channels, and internal systems — improving the usability, accuracy, timeliness, and reusability of CWILL's data assets.

This role is expected to continuously drive:

• More standardized data source ingestion
• Clearer data lakehouse and warehouse structure
• More automated data quality monitoring
• More platform‑driven data service capabilities
• Progressive adoption of agent‑based and automated approaches for data development, troubleshooting, documentation, and quality checks

• Data Ingestion & Pipeline Development
• Ingest data from internal and external business systems, third‑party platforms, SaaS products, and external data sources; handle data collection, sync, cleansing, and loading
• Participate in building offline and real‑time data pipelines using Sea Tunnel, Kafka, Flink, Spark, or similar technologies to improve ingestion stability and processing efficiency
• Handle practical challenges in data sync: authentication, pagination, rate limiting, failure retry, incremental sync, backfill, schema changes, and task anomalies
• Data Warehouse & Data Modeling; participate in layered data warehouse development across ODS, DWD, DWS, and ADS layers; build and maintain data models; support business domain modeling, metric standardization, shared data model development, and core table maintenance; optimize data organization and query performance on OLAP engines such as Doris to provide stable data support for product, operations, growth, customer success, and management analytics
• Data Quality & Data Governance; build and maintain data quality rules for core data pipelines; ensure data accuracy, completeness, consistency, and timeliness; participate in data validation, anomaly detection, alerting, and issue resolution; help improve stability of critical data pipelines; contribute to data governance capabilities including Data Hub…
