Agent Platform Engineer

The role

You will build infrastructure, tooling, and development workflows that allow AI agents to operate safely, reliably, and at scale. This work supports agents that generate customer interfaces, contribute to the company codebase, and automate workflows across engineering, go-to-market, and operations.

What you will do

• Build infrastructure for long-running agent execution, memory, planning, and stop-and-resume workflows
• Create platforms for AI agents to autonomously implement features, execute tests, and improve outputs
• Build secure, isolated execution environments
• 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 for collaboration with AI agents
• Create internal AI platforms for non-engineering teams to build custom agents
• Improve CI/CD, testing, deployment, and developer environments
• Strengthen security, reliability, and operational readiness of agent systems in production
• Evaluate and implement new tooling, storage, compute, and orchestration systems

Required qualifications

• 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

Nice to have

• Experience building infrastructure for AI agents is a major plus
