Python proficiency (must-have): production services, testing, profiling, packaging, clean architecture.
Large dataset handling in Python: memory/performance-aware processing (vectorization, chunking/streaming; pandas/NumPy/Polars or similar).
API development: REST and/or GraphQL, contract-first design, schema validation.
Database design + query optimization (SQL; Postgres/Aurora/Redshift a plus).
ETL/ELT patterns focused on correctness, validation, lineage, and maintainability.
Robust AWS experience: Lambda, API Gateway, IAM, CloudWatch, S3 (Step Functions, EventBridge, SQS/SNS are plus).
AWS Bedrock Agents concepts: Action Groups, orchestration, tool/function calling, secure interfaces.
Asynchronous processing with queues (DLQs, retries, idempotency).

Backend Responsibilities (Primary)
Build new agent tools/actions using AWS Bedrock Agent Action Groups (Lambda-backed tools).
Integrate existing internal/external APIs into Action Groups via OpenAPI schemas, standardize contracts (versioning, validation, error shapes).
Design and implement forecasting input pipelines:



ingestion, transformations, feature prep, aggregation, and validation.
Implement business logic and data transformation layers with solid test coverage.
Ensure robust error handling, retries, idempotency, and clear observability (logs/metrics/traces).
Secure tool interfaces (IAM policies, scoped permissions, secrets management) for secure function/tool calling.
Implement async workflows for long-running/high-throughput work (queues/events).

Nice-to-Have
OpenMetadata (or strong metadata/lineage management experience).
Experience building LLM products (tool orchestration, guardrails, evals).
Forecasting/time-series familiarity (helpful, not required).
