  • Integrate AI capabilities into business systems through APIs and Python-based automation

  • Evaluate AI outputs, troubleshoot model behaviour, and continuously improve accuracy, reliability, and user experience

  • Stay current with emerging AI technologies and recommend innovative solutions

About you

  • 3+ years of software engineering or AI engineering experience

  • Strong experience building real-world applications with LLMs, GenAI, AI agents, and RAG architectures

  • Hands-on experience with platforms such as Claude, Gemini, ChatGPT, or similar foundation models

  • Solid Python programming skills and experience integrating APIs and automation workflows

  • Experience with AI frameworks such as LangChain, LangGraph, LlamaIndex, AutoGen, or similar
