The Opportunity

We are seeking a FullStack Engineer to design, build and support secure, scalable enterprise web applications and AI-enabled experience layers.

  • Build and maintain the web application. This covers React JS front ends and Python (FastAPI) back-end APIs, deployed on the shared AWS platform.
  • Integrate enterprise systems such as SharePoint, Snowflake, Figma (REST API) etc. on the shared integration gateway.
  • Design data models on platform-managed Aurora PostgreSQL, DynamoDB and S3, and work with shared services such as document processing (Textract), vector search and the knowledge graph (Neo4j).
  • Ship through the shared CI/CD and Terraform (IaC) pipelines, with Entra ID / Cognito authentication and secure-by-design practices.
  • Develop GenAI features using Amazon Bedrock (Claude) through the shared model gateway, including prompt engineering, RAG over the vector store, Bedrock Guardrails, and evaluation and feedback loops.
