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 Platform Engineer, you’ll build the infrastructure, tooling, and development workflows that allow AI agents to operate safely, reliably, and at scale. Your work will support agents that generate customer interfaces, agents that contribute to Coframe’s own codebase, and automate workflows across engineering, go-to-market, and operations.

Every improvement to the agent platform makes our product more capable, accelerates Coframe’s engineering velocity, and expands what teams across the company can automate.

You’re a great fit if you have:

  • A strong platform or infrastructure engineering background

  • Strong software engineering fundamentals and experience designing scalable architectures

  • Experience building and operating distributed systems, developer platforms, internal tooling, or compute infrastructure

  • Experience with cloud infrastructure, serverless architectures, CI/CD, end-to-end testing, and production deployment strategies

  • Experience deploying, scaling, profiling, and operating AI agents or LLM-based systems in production

  • Familiarity with infrastructure for long-running execution, durable workers, isolated environments, remote browsers, and stateful workflows

  • Strong judgment across security, reliability, performance, cost, and iteration speed

  • A passion for engineering productivity and automating complex workflows

  • Comfort working across infrastructure, backend systems, AI, and developer experience

  • High ownership and the ability to operate effectively across ambiguous, fast-changing technical domains

  • Experience building infrastructure for AI agents is a major plus

What you’ll do:

  • Build infrastructure for long-running agent execution, memory, planning, and stop-and-resume workflows

  • Create platforms that allow AI agents to autonomously implement features, execute tests in isolated environments, analyze execution traces, and improve their own outputs

  • Build secure, isolated execution environments that allow agents to operate safely and reliably

  • Develop tracing, observability, evaluation, and monitoring infrastructure for autonomous AI agents

  • Design infrastructure for durable workers, serverless compute, remote browsers, and other agent execution systems

  • Build developer tooling that enables engineers to collaborate effectively with AI agents throughout the software development lifecycle

  • Create internal AI platforms that allow non-engineering teams to build custom agents and automate their own workflows

  • Improve CI/CD, testing, deployment, and developer environments

  • Strengthen the security, reliability, and operational readiness of agent systems running in production

  • Evaluate and implement new tooling, storage, compute, and orchestration systems

  • Resolve production incidents with both immediate fixes and long-term improvements

  • Create strong out-of-the-box platform defaults while supporting advanced configurations and use cases

Benefits:

  • Flexible (Unlimited) Paid Time Off

  • Medical, Dental, and Vision benefits for you and your family

  • Life Insurance and Disability Benefits

  • 401k Plan with Coframe match

  • Meals covered in-office

  • Gym membership

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.

“Coframe makes you feel like you have a team of 100 people.” - Replit team
