Apache Doris with Snowflake - Sunnyvale, CA/Austin, TX (Onsite)

Data Engineer — Snowflake & Apache Doris 

Location: Sunnyvale, CA/Austin, TX (Onsite)

W2 Contract/C2C

About the Role

We are seeking an experienced Data Engineer to design, build, and optimize scalable data pipelines and analytics infrastructure. The ideal candidate has hands-on expertise with Snowflake for cloud data warehousing and Apache Doris for real-time OLAP analytics, and is comfortable working across the full data lifecycle — from ingestion to transformation to serving high-performance queries for analytics and BI teams.

Responsibilities

·        Design, build, and maintain robust, scalable ETL/ELT pipelines to ingest structured and semi-structured data from multiple sources into Snowflake and Apache Doris.

·        Architect and optimize data models, schemas, and partitioning strategies in Snowflake and Doris to support high-throughput, low-latency analytical workloads.

·        Tune query performance, indexing, materialized views, and storage layout in Doris for real-time OLAP use cases.

·        Manage Snowflake warehouse sizing, cost optimization, resource monitors, and query performance tuning.

·        Build and maintain data orchestration workflows (e.g., Airflow, dbt, or similar) to automate pipeline scheduling, dependency management, and monitoring.

·        Implement data quality checks, validation frameworks, and observability/alerting for pipeline reliability.

·        Collaborate with data analysts, data scientists, and BI teams to understand reporting requirements and translate them into performant data models.

·        Support migration and integration projects between transactional systems, data lakes, Snowflake, and Doris.

·        Ensure data governance, security, and access control best practices (RBAC, data masking, encryption) across platforms.

·        Document data architecture, pipeline logic, and operational runbooks.

Required Qualifications

·        7+ years of experience as a Data Engineer or in a similar role.

·        Hands-on production experience with Snowflake — including SQL scripting, warehouse management, Snowpipe, Streams/Tasks, and performance tuning.

·        Hands-on experience with Apache Doris — including cluster architecture (FE/BE nodes), table models (Aggregate, Unique, Duplicate), materialized views, and real-time data loading (Stream Load, Routine Load, Broker Load).

·        Strong SQL skills and experience with data modeling (star/snowflake schemas, dimensional modeling).

·        Proficiency in Python commonly used in data engineering.

·        Experience with workflow orchestration tools (Apache Airflow, dbt, Dagster, or similar).

·        Familiarity with streaming/messaging systems (Kafka, Pulsar, or similar) for real-time data ingestion.

·        Solid understanding of data warehousing concepts, OLAP vs. OLTP design, and distributed systems fundamentals.

·        Experience with version control (Git) and CI/CD practices for data pipelines.

Preferred Qualifications

·        Experience migrating workloads from traditional data warehouses to Snowflake and/or Doris.

·        Familiarity with cloud platforms (AWS, Google Cloud Platform, or Azure) and infrastructure-as-code tools (Terraform, CloudFormation).

·        Experience with containerization/orchestration (Docker, Kubernetes) for deploying Doris clusters.

·        Knowledge of BI/visualization tools (Tableau, Looker, Superset, Power BI).

·        Background in cost optimization and capacity planning for large-scale analytical systems.

·        Contributions to open-source data engineering projects (e.g., Apache Doris community).
