About the role
About Coframe
At Coframe, we are building a future where user and agent interfaces can adapt, evolve, and personalize themselves. We are generating revenue, growing rapidly, and trusted by companies you definitely know.
Coframe is a primarily in-person company based in San Francisco, well-capitalized with backing from Khosla Ventures, Nat Friedman, the founder of Android, and others. Our team is small and talent-dense, consisting of competitive programmers, former founders (including our founder who previously co-founded a unicorn), and AI researchers from top institutions who have created some of the most popular open-source code generation projects.
About the role
As an Agent Engineer, you’ll build the core intelligence behind these systems. You’ll work on AI agents that create production-ready interfaces, reason through complex tasks, use tools, validate their own work, and continuously improve through real-world feedback.
Each new capability expands the range of experiences Coframe can create and optimize. Your work will increase experimentation velocity, improve output quality, and reduce the human effort required to build and maintain digital experiences.
You’re a great fit if you have
- 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
What you’ll 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
- 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

Why Coframe
Elite Team: Our founder is a serial entrepreneur who previously co-founded a $2B+ unicorn with Tom Brady and guest lectures AI at Stanford. Our team includes researchers from top institutions who created some of the world's most popular open-source code generation projects.
OpenAI: We’re the only marketing technology company officially partnered with OpenAI. Our engineers and researchers work directly with their team to co-train a model specifically for our use case, which is a differentiator, and a testament to the technical caliber of our team.
Inbound Leads: We’re currently growing at 120% QoQ with a consistent flood of inbound demand. We’re looking for the right saleshumans to capture this demand and market opportunity.
Top VCs: We’re backed by tier-1 investors including Khosla Ventures, Nat Friedman (former GitHub CEO), and Rich Miner (Android co-founder). Joining now means getting a seat on the rocket ship before our Series A: a once-in-a-lifetime opportunity to join in the early innings.
Already Crushing It: For our first product, we built proprietary generative AI technology that enables our Agents to autonomously design, code, debug, and deploy A/B tests, Landing Pages, and Personalization experiences. We effectively 10x testing velocity, replacing agencies, legacy tools, and the need to pull in-house designers and engineers for testing. In the last 6 months, we have already driven $221.4M in incremental revenue for our customers like Dropbox, Replit, and Intuit.
