  • Integrate, prompt, and debug LLMs and generative AI tools; own RAG or fine’tuning pipelines.
  • Ensure front’end and back’end systems interoperate flawlessly, minimize friction, optimize data flow, and enforce contracts.
  • Collaborate with product, research, design, and infra teams to define requirements, iterate rapidly, and ship production’grade code.
  • Monitor performance, reliability, and security.
  • Mentor junior engineers through code reviews, architecture reviews, and shared best practices.
Requirements
  • 5+ years of professional software engineering experience with end’to’end ownership in a full’stack role.
  • Deep expertise in Python, Node.js, React/TypeScript, and PostgreSQL.
  • Able to be hands’on with GCP, containerization (Docker/K8s), and building/supporting high’traffic systems.
  • Proven experience integrating AI/ML models (LLMs, NLP, RAG) into production apps.
  • Familiarity or strong interest in working with MCP servers.
  • Exceptional problem’solving skills and a product mindset: you think deeply about UX, performance, and business impact.
