Founding Engineer

Department: Engineering

Location: San Francisco

Employment Type: FullTime

About the Role

We're a seed-stage startup building an agentic integration platform used by paying enterprise customers. As our first engineering hire, you'll own core systems end-to-end and set the engineering patterns that every future hire builds on. You'll work shoulder-to-shoulder with the founders — we want your opinion, not just your code — and ship production-ready systems from day one.

This is a rare opportunity to shape the technical foundation of a company at its earliest stage, in one of the most exciting areas of software: AI agents and workflow automation.

What You'll Do

• Own the agent platform, infrastructure, and integrations runtime end-to-end.

• Define and establish the engineering patterns, standards, and architecture that every future engineer builds on.

• Collaborate directly with the founders, contributing strong technical opinions and leadership.

• Ship to production constantly, delivering reliable, observable, and scalable systems.

What We're Looking For

Must-haves:

• 3+ years of software engineering experience in fast-paced environments; startup experience strongly preferred.

• Proficiency in TypeScript and React for frontend, and Node.js for backend development.

• Demonstrated ability to build something 0 to 1 — whether at an early-stage startup or through a serious side project.

• Experience integrating or building workflows around large language models (LLMs) and agent-based platforms.

• Experience owning end-to-end feature development across frontend, backend, and infrastructure with measurable customer impact.

• Solid understanding of observability, monitoring, tracing, and reliable retry/queuing patterns in distributed systems.

• Hands-on experience with AWS for cloud infrastructure and PostgreSQL for data storage.

Nice to have:

• Familiarity with Bun, Effect-TS, or Kubernetes.

• Background at a high-growth product company or enterprise SaaS environment.

Compensation & Benefits

• Salary: $150,000 – $250,000 USD annually, depending on experience.

• Equity participation as the first engineering hire.

• Visa sponsorship available.
