Key Responsibilities & Deliverables
This role is focused on the successful completion of specific tasks and deliverables. Your responsibilities will include:
- Streaming Data Pipelines: Build and maintain streaming ingestion, API-based data workflows, and distributed data transformations using AWS services (Kinesis, Lambda, Glue/Spark, EMR, S3).
- API Development: Develop and maintain REST APIs for data ingestion and consumption.
- Data Modeling: Develop and optimize data lake and operational data models for near-real-time use cases, supporting downstream loading into Snowflake.
- DevOps/Reliability: Contribute to the platform’s CI/CD, automated testing, and release workflows, working to improve reliability, automation, and observability.
- On-Call Support: Participate in an on-call rotation (1 week duty rotation every 6 weeks) to provide support for the team’s data systems and services.
We are looking for someone with a proven track record of successful contract engagements. The ideal candidate will have:
- 3 years of hands-on experience building production data systems or data services.
- Deep expertise in AWS for building applications, including services like Lambda, S3, API Gateway, IAM, Glue/Spark, and Kinesis. This is not a SQL/ELT or Databricks-notebook-driven role—you need to be a subject matter expert in building production systems.
- Solid proficiency in Python (and ideally Scala).
- Demonstrated ability to debug and reason about distributed data systems (streaming pipelines, Spark on EMR/Glue, APIs, queues, storage layers).
- Practical experience with infrastructure-as-code (Terraform or CloudFormation).
- Strong communication skills to provide clear and concise status updates to the project team.
- W2 only (No C2C or 1099 contractors)
