  • Partnering with consulting teams to translate business needs into robust AI solutions.
  • Mentoring mid-level engineers and shaping internal AI engineering best practices.
  • Lead AI technical discovery, PoCs, and production rollouts with clients.
  • Contribute to AI service offerings, accelerators, and internal frameworks.

Required Experience & Skills

  • 5+ years of professional software engineering experience, including production AI systems.
  • Advanced expertise in Python and distributed system design.
  • Proven experience designing and implementing agentic or multi-agent AI architectures.
  • Deep hands-on experience with LangGraph, LangChain (advanced usage), MCP, or similar orchestration approaches.
  • Strong experience with LLMs, RAG pipelines, and vector databases.
  • Cloud-native deployment experience using AWS (Bedrock), Azure (Azure OpenAI), or GCP (Vertex AI).
  • Solid understanding of Responsible AI, security, and governance considerations.
  • Ability to clearly communicate complex AI concepts to both technical and executive stakeholders.

Leadership Expectations
