About the RoleThis is the first engineering hire at an early-stage B2B SaaS company building an agentic integration platform with paying enterprise customers. You will own core systems end-to-end and set the engineering patterns every future hire builds on, working directly with the founders to ship production-ready software.
What You'll Do- Own the agent platform, infrastructure, and integrations runtime end-to-end.
- Define the engineering standards and architectural patterns the growing team will inherit.
- Collaborate closely with the founders, contributing technical opinion and leadership, not just code.
- Ship to production consistently, delivering reliable and observable systems with measurable customer impact.
What We're Looking For- 3 to 9 years of professional software engineering experience building and shipping production systems.
- Demonstrated ability to build something from zero to one, in an early-stage startup or a serious side project.
- Experience integrating or building workflows around large language models (LLMs) and agent-based platforms.
- Proficiency in TypeScript for full-stack development, React for frontend, and Node.js for backend.
- Experience with AWS for cloud infrastructure and PostgreSQL for data storage and database design.
- Track record of owning end-to-end feature development across frontend, backend, and infrastructure.
- Experience implementing observability, monitoring, and tracing in production systems.
- Experience building reliable retry and queuing patterns in distributed systems.
- Strong computer science or engineering fundamentals, ideally from a rigorous academic background.
- Background at an early-stage, venture-backed startup, or comparable fast-paced environment.
- Based in the San Francisco Bay Area, or US-based with a concrete relocation plan to San Francisco.
