• Get to Know Us
• What You’ll Do
• Design, build, and maintain features in our core Python API, with a focus on performance, correctness, and maintainability.
• Design, build, and operate workflow orchestration for large-scale, long-running workloads using tools such as Prefect or Temporal, including scheduling, retries, idempotency, state management, and failure recovery.
• Build orchestration that scales reliably across many concurrent workflows, with clear visibility into progress, failures, and throughput.
• Comfort reading and untangling unfamiliar, complex SQL, and the judgment to optimize or refactor it safely in production.
• Build and operate high-throughput data processing and ETL pipelines that turn large volumes of raw assessment data into reliable, queryable datasets.
• Contribute to datalake architecture on AWS, including storage layout, partitioning, schema evolution, and query performance.
• Deploy and manage services on Kubernetes, and take part in cluster operations, release management, and capacity planning.
