Job description

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
