Founding Engineer

About the Role We're a seed-stage startup building an agentic integration platform used by paying enterprise customers. We're looking for our first engineering hire — someone who will own core systems end-to-end, set the engineering patterns that every future hire builds on, and work shoulder-to-shoulder with the founders to ship production-ready software every day. This is a high-ownership, high-impact role for an engineer who thrives in ambiguity, loves building from zero to one, and wants their technical fingerprints on the entire stack. What You'll Do Own core systems end-to-end: agent platform, infrastructure, and the integrations runtime. Define and establish the engineering patterns and standards that every future hire will build upon. Work directly with the founders — your opinions and technical leadership matter as much as your code. Ship to production constantly, delivering reliable, observable, and well-instrumented systems. What We're Looking For Must-haves (dealbreakers): 3+ years of software engineering experience building and shipping production systems. Proven ability to build something 0 to 1 — in an early-stage startup or through serious side projects. Proficiency in TypeScript and React for frontend development. Proficiency in Node.js for backend development. Hands-on experience integrating or building workflows around large language models (LLMs) and agent-based platforms. Required skills: Experience with AWS for cloud infrastructure. Experience with PostgreSQL for data storage and database design. Experience owning end-to-end feature development across frontend, backend, and infrastructure with measurable customer impact. Experience implementing observability, monitoring, and distributed tracing in production systems. Experience building reliable retry and queuing patterns in distributed systems. Nice to have: Experience working in fast-paced startup environments. Experience setting engineering patterns and standards for growing teams. Compensation & Benefits Salary: $150,000 – $250,000 USD annually, depending on experience. Visa sponsorship is available. Location On-site in San Francisco, CA. This is not a remote role.
