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 strong test coverage.
Ensure robust error handling, retries, idempotency, and clear observability (logs/metrics/traces).
Secure tool interfaces (IAM policies, scoped permissions, secrets management) for safe 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).
