Required experience
  • Minimum 5 years of professional backend engineering experience is required; expert in Python (3.12+) and production AWS Lambda / serverless (boto3).
  • Demonstrated generative-AI / LLM application experience: AWS Bedrock or the Anthropic / OpenAI APIs — prompt engineering, few-shot design, tool and function calling, retrieval-augmented generation, and evaluation of model output.
  • Strong in BOTH NoSQL and relational databases: DynamoDB (single-table design, GSIs) AND PostgreSQL (schema design, complex SQL, transactions).
  • REST API design and implementation behind API Gateway; integrating third-party APIs. Testing and version-control discipline.
Preferred
  • ClickHouse or other OLAP / columnar analytics; large-scale query optimization.
  • Vector stores and embeddings; retrieval-augmented generation over mixed structured and unstructured data.
  • Model Context Protocol (MCP).
  • Geospatial work (routing, Mapbox); multi-tenant SaaS; political-technology or regulated-communications experience.
  • You will be working on patent pending technology. Strong Math background preferred.
