What you'll do

  • Design multi-agent systems with coding-focused agents such as code writer, reviewer, tester and deployer
  • Write the prompts, logic and scaffolding that guide each agent's behavior
  • Handle tool use, enabling agents to access the file system, test runners, version control and internal APIs
  • Evaluate and refine agents' output, performance, collaboration patterns and feedback loops
  • Prototype new coding assistant workflows using open-source LLMs and internal knowledge bases
  • Lead architecture discussions on agentic build pipelines or automated PR generation
  • Collaborate with a cross-functional team to build AI-powered interfaces for internal tooling
  • Help define the evaluation framework for AI contributions in terms of accuracy, speed and impact
  • Mentor teammates on combining TypeScript and AI tools to accelerate UI prototyping
  • Explore best practices for safely and securely integrating generative AI into a public sector codebase
  • Participate in the on-call rotation

What we're looking for

  • 5+ years of professional software engineering experience
  • Proficiency with at least part of the stack: Java, TypeScript + React, and MySQL
  • Extensive applied experience with AI-assisted development tooling such as Cursor, Windsurf, LLM APIs, codegen platforms, vector databases, agentic frameworks like LangChain, or custom-built systems
  • A strong product mindset and interest in building for real-world impact
  • A bias toward experimentation, iteration and continuous learning
  • Comfort operating in ambiguity and helping define best practices in a rapidly evolving space
  • Hands-on experience applying generative AI tools to real-world development workflows
