  • Model clean schemas and access patterns for Postgres; use Redis for caching and rate-limiting; integrate vector DBs (Pinecone).
  • Contribute to our Next.js frontend where necessary.

Requirements

  • Relevant experience building systems & deploying enterprise-grade products
  • Ability to make decisions and drive results independently
  • Strong proficiency in full-stack web development technologies such as Python, FastAPI, Docker, AWS
  • Experience working with LLMs such as GPT, Claude and Gemini to create LLM-based workflows, RAG Pipelines and agentic solutions. (Either formally or through projects/experimentation)
