Founding Engineer, Infrastructure

About the Role

Join an early-stage B2B SaaS team as its first infrastructure engineer, owning the runtime, agent infrastructure, observability, and self-hosted deployment experience. You will work closely with the founding team, establish the platform patterns for future hires, and have a path toward leading this domain.

What You'll Do

• Build and operate a cloud runtime for integrations, including durable execution, sandboxed isolation, and resilient recovery.

• Develop infrastructure for coding agents that write, test, and deploy integration code in production.

• Design observability across logs, metrics, and tracing for integrations and agents.

• Build and maintain single-tenant, self-hostable product deployments.

• Own infrastructure and platform decisions end to end, and establish engineering practices for future infrastructure hires.

• Ship production systems regularly and help grow the team responsible for this area.

What We're Looking For

• Three to nine years of professional software engineering experience, including at least three years in a fast-moving, high-growth startup environment.

• Production experience operating, scaling, and debugging Kubernetes, with end-to-end ownership of cloud infrastructure or a platform.

• Hands-on cloud infrastructure experience and a strong understanding of production observability across logs, metrics, and tracing.

• Experience using AI coding agents effectively while applying sound production engineering judgment.

• Experience building self-hosted, single-tenant product deployments is valuable.

• A completed or in-progress engineering, computer science, or quantitative degree and strong technical fundamentals.
