Description

About the Role

This is the first engineering hire at an early-stage agentic integration platform serving paying enterprise customers. You will own core systems end-to-end and set the technical foundation that every future engineer builds on, working directly alongside the founders.

What You'll Do

  • Own the agent platform, infrastructure, and integrations runtime from design through production.

  • Establish engineering patterns and standards that scale with the growing team.

  • Collaborate closely with the founders, contributing technical opinion and leadership, not just code.

  • Ship reliable, observable production systems continuously 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, whether at an early-stage startup or through a serious side project.

  • Proficiency in TypeScript for full-stack development, React for frontend, and Node.js for backend.

  • Experience integrating or building workflows around large language models (LLMs) and agent-based platforms.

  • Hands-on experience with AWS for cloud infrastructure and PostgreSQL for data storage and database design.

  • Experience owning end-to-end feature development across frontend, backend, and infrastructure.

  • Experience implementing observability, monitoring, tracing, and reliable retry and queuing patterns in distributed systems.

  • A strong computer science or engineering academic background (Bachelor's, Master's, or PhD).

  • Background at an early-stage, venture-backed startup; a career spent exclusively at large enterprises or big tech is not a fit for this role.

  • Genuine enthusiasm for joining as employee number one and shaping a company from the ground up.

Compensation & Benefits

Salary range: $150,000 to $250,000 USD annually. Visa sponsorship is available where an O-1 visa is a realistic option.

Location

On-site, five days a week in San Francisco, California. Candidates currently based elsewhere in the US are welcome to apply with a concrete, dated relocation plan to San Francisco.
