About the role

  • Architect and implement AI-assisted workflow building capabilities (workflow creation, editing, and suggestions)
  • Design systems that provide LLMs with the right context: workflow state, user intent, constraints, and history
  • Build tool-driven agent behaviour: calling internal tools, validating outputs, correcting mistakes, and recovering gracefully
  • Develop evaluation benchmarks and automated testing for AI output quality
  • Create fast iteration loops: experiment, measure, improve - shipping changes quickly with confidence
  • Collaborate closely with engineering, product, and design to deliver a polished Copilot experience
  • Stay current with advances in LLMs and AI developer tools and bring practical improvements into the product

Requirements

  • 7+ years of experience building web-based products, ideally SaaS developer tooling products
  • Strong fullstack engineering skills in TypeScript / Node.js and API design
  • Hands-on experience building complex AI-powered product features in production
  • Experience building a tool-using AI system or “agentic” workflow, such as:
  • - coding agents, AI copilots, or assistant systems
  • - multi-step tool calling pipelines
  • - structured generation with validation and recovery
  • Strong understanding of how to make LLM outputs reliable:
  • - prompt design and iteration
  • - context construction and optimization
  • - managing constraints, failure modes, and edge cases
  • Experience building or using evaluation frameworks for LLM-based systems:
  • - benchmarks, scoring, regression tests, offline vs online evaluation
  • - Solid understanding of what to evaluate
  • A product mindset: you care deeply about user outcomes, not just model behaviour
  • A bias for action: you iterate quickly, learn fast, and ship improvements continuously
