Founding Engineer - Infrastructure

ABOUT THE ROLE This is the first infrastructure hire at a seed-stage agentic integration platform, working directly with the CTO on a clear leadership track. You will own the full infra and platform layer from day one, setting the patterns every future infrastructure hire builds on. The work is foundational: what you ship defines how the product scales. WHAT YOU'LL DO - Design and operate a mini cloud platform providing durable execution, sandboxed isolation, and self-healing for an integration runtime. - Build and scale the agent infrastructure that runs coding agents writing, testing, and deploying integration code in production. - Implement full observability across logs, metrics, and tracing for every integration and agent. - Ship a self-hostable, single-tenant deployment of the platform as a standalone product. - Set engineering patterns that every future infrastructure hire will follow. - Help recruit and, within roughly a year, grow into leading the infrastructure team. - Work as a peer to the founding team and ship to production constantly. WHAT WE'RE LOOKING FOR - 3 to 9 years of professional software engineering experience, ideally at a high-growth startup backed by a top-tier investor or founded/co-founded by you. - Based in the San Francisco Bay Area, or US-based with a firm, dated plan to relocate there; able to work on-site five days a week. - Hands-on experience operating, scaling, and debugging Kubernetes in production. - End-to-end ownership of cloud infrastructure or a platform, not just contribution to one. - Strong observability experience covering logs, metrics, and distributed tracing. - Experience building or shipping self-hostable, single-tenant product deployments is a plus. - Comfortable using AI coding agents effectively while maintaining production-quality engineering judgment. - Solid CS or quantitative fundamentals from a university degree (completed or in progress); strong academic foundations preferred. - Fluency with TypeScript, PostgreSQL, AWS, and Docker alongside Kubernetes. COMPENSATION & BENEFITS Salary range: $175,000 to $300,000 USD annually. Visa sponsorship (O-1) is available for qualified candidates. LOCATION On-site, five days a week in San Francisco, CA, United States.
