About the Role:
We are looking for a senior, polyglot full-stack engineer to build and own services across a large-scale supply-chain analytics and alerting platform. You will work end-to-end — from streaming data ingestion and Big Query analytics, through Java/Spring Boot APIs, to a modern React/Next.js frontend — and contribute to an emerging agentic-AI capability. This is a hands-on role for someone who can operate as both an individual contributor and a lightweight architect, owning services outright and driving them to production.
You will routinely move between four stacks (Java/Spring Boot, Apache Beam on GCP Dataflow, Python/Fast API, and React/Next.js), so we value breadth and the ability to context-switch as much as depth in any one area.
What You'll Do:
Design, build, and own backend services in Java / Spring Boot, exposing REST and Graph QL APIs over Big Query and Mongo DB.
Build and harden streaming and batch data pipelines using Apache Beam on GCP Dataflow, ingesting high-volume supply-chain event feeds (shipping notices, inventory adjustments, orders, transfers)



into Big Query.
Author and tune analytical Big Query queries that detect operational conditions and generate prioritized alerts; manage daily vs. weekly pipeline scheduling.
Implement alert-lifecycle and worklist features (ingest, route, snooze, resolve, reactivate, dismiss, archive) with reliable, idempotent processing at scale.
Optimize performance over heavy data aggregations — parallel query execution, caching layers, materialized views, and thread-pool tuning.
Build agentic-AI workflows on Python / Quick API using Lang Graph / Lang Chain and Vertex AI / LLMs, including human-in-the-loop email automation (SMTP/IMAP) and knowledge-base-driven prompting.
Develop frontend features on React 18 / Next.js / Type Script with Redux Toolkit + redux-saga, including data-rich dashboards and conversational/agentic UI.
Implement cross-cutting concerns: role-based access, secure impersonation, scoped JWT
