Seed-stage startup building agentic integration platform seeks Founding Engineer to own core systems. On-site in SF, visa sponsorship available. Salary $150k-$250k.
ABOUT THE ROLE
A fast-growing, seed-stage startup building an agentic integration platform for enterprise customers is hiring its first engineering hire. This is a rare opportunity to own core systems end-to-end, set the engineering patterns that every future team member will build on, and work shoulder-to-shoulder with the founding team to ship production-ready software.
The platform is live, has paying enterprise customers, and is growing quickly. You won't be building in a vacuum — you'll be shipping to production constantly and seeing real impact on real users from day one.
WHAT YOU'LL DO
- Own core systems end-to-end: agent platform, cloud infrastructure, and the integrations runtime.
- Set the engineering patterns, standards, and architecture decisions that every future hire will build upon.
- Work directly with the founders — your opinions and technical leadership are genuinely needed, not just your code.
- Ship reliable, observable, production-grade systems continuously.
- Drive end-to-end feature development across frontend, backend, and infrastructure with measurable customer impact.
WHAT WE'RE LOOKING FOR
Must-haves
- 3+ years of software engineering experience building and shipping production systems.
- Proven track record of building something from 0 to 1 — in an early-stage startup or a serious side project.
- 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.
- Experience with AWS for cloud infrastructure.
- Experience with PostgreSQL for data storage and database design.
- Experience implementing observability, monitoring, and tracing in production systems.
- Experience building reliable retry and queuing patterns in distributed systems.
Nice-to-haves
- Prior experience in fast-paced startup environments.
- Experience setting engineering patterns and standards for growing teams.
- Familiarity with Kubernetes or container orchestration at scale.
COMPENSATION & BENEFITS
- Salary: $150,000 – $250,000 USD annually
- Visa sponsorship is available.
