  • Collaborate with product and design teams to ship AI-powered features in rapid development cycles

  • Contribute to MLOps pipelines and best practices for deploying and monitoring models in production

What We're Looking For

  • 3+ years of experience in backend engineering or applied ML, preferably at a startup or fast-moving environment

  • Strong experience with Python , FastAPI , and RESTful APIs

  • Hands-on experience with RAG architectures , vector databases , and LLM APIs (OpenAI, Anthropic, Mistral, etc.)

  • Solid understanding of embedding models , prompt engineering, and semantic search

  • Comfort working with SQL and structured datasets

  • Bonus: Experience with LangChain, Haystack, or similar frameworks
