Founding Infrastructure Engineer

ABOUT THE ROLE This is the first infrastructure hire at a seed-stage gig economy and flexible staffing platform, working directly with the CTO as a true founding team member. You will own the entire infra and platform layer from day one, with a clear path to leading the infrastructure team as it grows. The work directly shapes how integration runtimes and AI coding agents run reliably at scale in production. WHAT YOU'LL DO - Own and evolve a mini cloud platform for integration runtime: durable execution, sandboxed isolation, and self-healing systems. - Build and operate the agent infrastructure that supports coding agents writing, testing, and deploying integration code at scale in production. - Design and maintain full observability across logs, metrics, and tracing for every integration and agent run. - Ship a self-hostable, single-tenant deployment of the platform as a first-class product. - Set the engineering patterns and standards that every future infrastructure hire will build on. - Work as a peer to the founding team, shipping to production constantly. - Help hire and, within roughly a year, grow into leading the infrastructure team. WHAT WE'RE LOOKING FOR - 3 to 9 years of professional software engineering experience, with at least 3 of those years in a fast-moving, high-growth startup environment. - Hands-on experience operating, scaling, and debugging Kubernetes in production. - End-to-end ownership of cloud infrastructure or a platform, not just contributing to one. - Practical cloud infrastructure background rather than primarily data infrastructure experience. - Strong observability design skills across logs, metrics, and tracing for production systems. - Comfortable using AI coding agents effectively while maintaining rigorous production engineering judgment. - Experience building self-hostable, single-tenant product deployments is a strong plus. - Prior experience at a venture-backed startup or as a founder; a career spent only at large enterprises does not fit this role. - Strong computer science fundamentals from a rigorous technical degree program. - Fluency in TypeScript, PostgreSQL, AWS, and Docker. COMPENSATION & BENEFITS Salary range: $175,000 to $300,000 USD annually. Visa sponsorship is available where an O-1 visa is a realistic path. LOCATION On-site, five days a week in San Francisco, CA, United States. Candidates based elsewhere in the US are welcome with a concrete, dated relocation plan to San Francisco.
