Key Responsibilities
- Design and implement scalable data ingestion pipelines using AWS services (S3, Redshift, EMR, Kinesis, Firehose, Lambda, IAM) and arenaflex‑specific tools to collect raw data from diverse sources such as transactional logs, clickstreams, supplier feeds, and third‑party marketplaces.
- Develop and maintain robust ETL processes that transform raw data into clean, enriched datasets ready for consumption by machine‑learning models, business intelligence dashboards, and downstream analytics applications.
- Collaborate with data scientists, product owners, and business analysts to understand data requirements, define data contracts, and ensure the pipelines deliver high‑quality, timely data that meets performance SLAs.
- Build and manage data lakes and data warehouses on Amazon S3 and Redshift, implementing best practices for partitioning, indexing, and metadata management to optimize query performance and cost efficiency.
- Perform data profiling, validation, and quality checks to detect anomalies, missing values, and schema drift, and proactively resolve data integrity issues.
- Monitor, troubleshoot, and optimize pipeline performance using CloudWatch, AWS X‑Ray, and custom dashboards, ensuring reliability under high‑throughput workloads.
- Document data models, pipeline architecture, and operational procedures to facilitate knowledge sharing and enable rapid onboarding of new team members.
- Stay current with emerging data technologies and propose innovative solutions that improve scalability, reduce latency, and enhance the overall data ecosystem.
A Day in the Life
Each day you will start by reviewing the health of your data pipelines, checking for any alerts or performance degradations. You’ll then dive into a sprint planning meeting with product managers and data scientists to prioritize new data sources and feature enhancements. Throughout the day, you’ll write SQL and Python code, configure AWS Glue jobs, and fine‑tune EMR clusters to handle petabyte‑scale workloads. You’ll also spend time mentoring junior engineers, conducting code reviews, and sharing best practices across the broader data engineering community at arenaflex.
