Description

  • Design multi-agent systems with coding-focused agents such as code writers, reviewers, testers, and deployers.
  • Write prompts, logic, and scaffolding that guide each agent’s behavior.
  • Enable agents to use tools including the file system, test runners, version control, and internal APIs.
  • Evaluate and refine agent output, performance, collaboration patterns, and feedback loops.
  • Prototype new coding assistant workflows using open-source LLMs and internal knowledge bases.
  • Lead discussions on agentic build pipelines and automated pull request generation.
  • Collaborate with cross-functional teammates to build AI-powered internal tooling interfaces.
  • Help define evaluation frameworks for AI contributions, including accuracy, speed, and impact.
  • Explore safe and secure ways to integrate generative AI into a public sector codebase.

Requirements

  • 5+ years of professional software engineering experience.
  • Proficiency with at least part of Mark43’s stack: Java, TypeScript + React, and MySQL.
  • Extensive applied experience with AI-assisted development tools such as Cursor, Windsurf, LLM APIs, code generation platforms, vector databases, LangChain, or custom-built systems.
  • Hands-on experience applying generative AI tools to real-world development workflows.
  • 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.
  • Applicants must be authorized to work in the country where the role is hired, and Mark43 cannot sponsor or take over employment visa sponsorship at this time.
  • Ability to work remotely from Canada, the UK, or one of Mark43’s approved U.S. states.
