About the role

  • Develop Agents and Multi-agent systems: Design and implement AI agent and extend existing agents with new capabilities. This includes managing the agent’s context (using techniques like sub-agents, retrieval based context management, sliding context windows, etc.).
  • Develop Tools for agents: Develop complex tools for agents like computer use, browser use, etc.
  • Multi-agent orchestration and tool calling: Research and develop systems on how agents should collaborate, and how agents should call tools.
  • Fullstack development: Build and maintain production-grade APIs and AI-powered features, from backend services to user-facing experiences.
  • Evaluate and improve: Evaluate AI’s performance using evaluations and tests to then iterate on prompts, agent tools and agents orchestration to improve output quality and reliability.

Requirements

  • 4+ years in full-stack software development, ideally developing practical and production-ready AI applications or features that utilise Gen AI/ LLMs / RAG.
  • Strong programming skills in Python and Typescript, including experience using AI-assisted coding tools.
  • Deep understanding of foundational models, prompt engineering, and fine-tuning techniques.
  • Understanding of software design, service architecture, and scalable systems.
  • Passion for building AI-enhanced user experiences, not just theoretical ML solutions.
  • Prior start-up or tech company experience is a plus - especially where you’ve worn multiple hats or shaped early products.
