Founding Engineer

Department: Engineering

Location: San Francisco

Employment Type: FullTime

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.
