Agent Engineer

The role

You will build the core intelligence behind AI systems. You will work on AI agents that create production-ready interfaces, reason through complex tasks, use tools, and improve through real-world feedback.

What you will do

• 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

Required 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
