About the role

Engineer the core intelligence behind Coframe’s AI agents, building production-ready interfaces, reasoning, tool use, and continuous improvement through real-world feedback.

Responsibilities

  • Build AI agents that generate high-quality user interfaces, client-side features, and product experiences
  • Develop agent workflows for planning, reasoning, tool use, and multi-step execution
  • Build systems that allow agents to autonomously generate, test, verify, and improve their own work
  • Create validation systems that catch bugs, off-brand outputs, and poor user experiences before launch
  • Develop online and offline evaluation systems for generated code, designs, and user experiences
  • Build agent memory, feedback loops, and learning pipelines that improve performance over time
  • Integrate agents with browsers, development environments, internal platforms, and other tools
  • Build monitoring systems that detect quality issues and regressions after rollout
  • Improve orchestration across generation, validation, deployment, monitoring, and learning loops
  • Turn manual engineering and operational workflows into scalable, reliable agents
  • Build production systems capable of safely generating and improving hundreds of thousands of interfaces
  • Work with technical and non-technical teams to translate feedback into metrics, evaluations, and product improvements

Qualifications

  • Strong software engineering fundamentals and experience shipping reliable production systems
  • Experience building LLM applications, AI agents, autonomous workflows, or code generation systems
  • Experience with prompting, evaluation, retrieval-augmented generation, tool use, or agent frameworks
  • Experience building systems for planning, reasoning, and multi-step execution
  • The ability to design reliable systems around nondeterministic model behavior
  • Experience with automated testing, evaluation systems, and parallel execution
  • Strong web engineering skills and product judgment for what makes a high-quality interface
  • Experience integrating agents with browsers, development tools, APIs, or internal platforms
  • Comfort working across the stack to solve complex engineering problems
  • The ability to turn qualitative feedback into measurable improvements to agent performance
  • Curiosity, pragmatism, and excitement about working on problems with no established playbook
  • A track record of exploring new approaches to code generation and agent development beyond standard tools and frameworks
