About the Role
This 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.
