AWS Cloud Engineering

Location: Sunnyvale, CA (100% onsite)
Salary Range: $130K - $140K per year

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.

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, GCP, 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).
