San Francisco · On-site Full-time Mid Level $120k – $150k/yr 3w ago

About the role

Most agents today are for coding, but the company is building AI agents for non-technical people, starting with sales teams.

As the team grows, we are looking for a Full Stack Engineer. You’ll move between classic SaaS integration problems, user-facing requests, and AI agent infrastructure.

This position targets a competitive base salary (around a six-figure range) and a meaningful equity grant (around ~1%+).

Responsibilities

  • Collaborate closely with a tight-knit team to develop and implement an AI agent targeting business outreach for non-technical operators
  • Engage in hands-on full-stack development, focusing on multi-agent systems and human–agent interaction
  • Contribute to an upcoming product launch, ensuring readiness and continued improvement after launch
  • Continuously innovate and refine the application layer of AI agents to enhance performance and usability

Qualifications

  • 2–5 years work experience at early-stage startups — familiar with production systems and infrastructure ready to scale
  • Production experience across the web stack — able to ship across frontend and backend (example technologies include React/TypeScript, Python, and SQL)
  • Early-stage ready — interest in joining as one of the first employees in a founding engineering role

Benefits

  • Equity grant (example range: 1–3% for early tenure)
  • Team experienced in building agentic systems over recent years and prepared to scale
  • Market focus: building products for the large majority of users who do not code

Interview Process

Given this is a founding role, there will be a comprehensive process spanning several stages.

  • Intro call — video screen with a founder or senior leader
  • Technical deep dive — interview with senior engineering leadership
  • May include an in-person or on-site work trial where feasible
