Agent Engineer

About the role

Coframe is building AI systems that autonomously generate, verify, deploy, and personalize living interfaces at scale. As an Agent Engineer, you'll build the core intelligence behind these systems.

Responsibilities

• Build AI agents that create production-ready interfaces, reason through complex tasks, use tools, validate their own work, and continuously improve through real-world feedback.
• Increase experimentation velocity, improve output quality, and reduce the human effort required to build and maintain digital experiences.
• Design reliable systems around nondeterministic model behavior.
• 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.
• Build online and offline evaluation systems for generated code, designs, and user experiences.
• Create 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.

Requirements

• 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 turn qualitative feedback into measurable improvements to agent performance.
• Curiosity, pragmatism, and excitement about working on problems with no established playbook.

Qualifications

• A track record of exploring new approaches to code generation and agent development beyond standard tools and frameworks.

Skills

• Strong web engineering skills and product judgment for what makes a high-quality interface.

Benefits

• Flexible (Unlimited) Paid Time Off
• Top-of-the-line Medical, Dental, and Vision benefits for you and your family
• Life Insurance and Disability Benefits
• 401k Plan with Coframe match
• All meals fully covered in-office
• Gym membership

About us

At Coframe, we are building user interfaces for humans and agents that can self-improve. We call this idea living interfaces. We are a primarily in-person company based in San Francisco. We're backed by Khosla Ventures (co-led Seed + Series A), Hanabi Capital, Nat Friedman, etc. We're growing 100% QoQ and our customers include Apple, BCG, Cash App, and Dropbox. Our founder previously co-founded a unicorn, and our team consists of competitive programmers, AI PhDs, and several former exited founders.
