Client is hiring Founding Full Stack Engineers to build the core platform from the ground up. The company is developing autonomous AI agents that automate key business functions - think growth, market discovery, and product orchestration - with a bold long-term vision around using AI to systematically create and scale new ventures. They already have paying customers, a multi-year runway, and backing from a top-tier Silicon Valley venture fund that beat out several other elite firms for the deal.
The Opportunity
You'll be on a small elite, high-intensity team. You'll report directly to the CEO and have massive ownership over the product and technical architecture. Day-to-day, you'll be building the full-stack infrastructure that powers AI agents across the growth stack - designing orchestration layers, event-driven workflows, and data pipelines, while also shipping polished frontend experiences. This is a true 0→1 role where every system you build becomes the foundation for what comes next.
Qualifications
What You'll Build
The core platform where autonomous AI agents operate - coordinating across tasks like content generation, ad optimization, market research, and campaign management
Backend orchestration systems that allow multiple AI agents to collaborate and execute reliably at scale
Frontend and generative interfaces that enable both internal teams and customers to interact with intelligent agents
End-to-end product features that ship directly to paying customers
What We're Looking For
3–6+ years of experience building full-stack products from scratch
Deep proficiency in TypeScript, React, Next.js, Node.js, and PostgreSQL - TypeScript is non-negotiable
Strong systems design and backend architecture skills
Experience or genuine curiosity with AI-driven systems, LLMs, multi-agent workflows, or calling AI APIs
Prior experience at a VC-backed startup or top tech company is required; FAANG is fine if paired with startup sensibilities
CS degree from a strong undergraduate program (especially important if you have ~4 years of experience)
Hackathon wins or notable side projects are a bonus
You move fast, think clearly, communicate well, and have a bias for action
Must be hands-on - this is an IC role, not a management position
Why is This a Great Opportunity
The company is building AI agents that handle core business functions - from identifying market opportunities to executing growth strategies - so that new products and companies can be launched faster and with less manual effort.
