Responsibilities
  • Set technical direction for the pod and own architecture decisions within scope
  • Deliver production-ready code for roughly 50%+ of your time across backend AI services, LLM orchestration, and frontend integration

Requirements
  • Proven track record with 5+ years in software engineering, owning complex backend systems end to end
  • Hands-on experience of 1–2+ years running LLM-era AI/ML platforms such as LangChain, LangGraph, or Bedrock in production; candidates with strong pre-LLM ML experience (TensorFlow, scikit-learn) who have clearly shifted to generative AI are also considered
  • Expert-level Python skills for backend services and AI integration as the primary language for backend and AI work
  • Practical expertise using LangChain, LangGraph, and LangSmith to orchestrate multi-step, multi-agent workflows with evaluation/observability
  • Demonstrated experience delivering at production scale with AWS, Docker, and microservices
  • Proficiency with GitHub Actions, ArgoCD, and OpenTofu/Terraform
  • Baseline capability in secure coding practices, auth/authz awareness, and data governance
  • Strong skills in API design for RESTful APIs and microservices
  • English proficiency at B2 (Upper-Intermediate) level or above
Nice to have
  • Strong React and TypeScript skills to contribute to UI-layer code and review frontend changes
  • Awareness of MCP (Model Context Protocol) and new standards for agent interoperability
  • Familiarity with AI evaluation tools such as RAGAS or custom eval frameworks
  • Experience designing and tuning RAG pipelines using vector databases like Amazon Kendra and OpenSearch
  • Knowledge of IAM and CIAM plus experience managing unstructured data (images, videos) with prompt context handled via LangGraph State
