The Company

Our client is an early-stage tech startup shaping the next evolution of online commerce.
In a world where AI agents will browse, compare, and purchase on behalf of users, this company is building the infrastructure that will enable merchants to interact seamlessly with these agentic systems.

They transform traditional websites into AI-ready endpoints fully compatible with LLMs, allowing products to be discovered, understood, and purchased directly by autonomous agents.

They are pioneers in what many consider the next trillion-dollar wave of the digital economy: agentic commerce.
The company is already generating revenue and moving quickly into a breakout phase.

The Role

As a Founding Engineer with a DevOps focus, you will play a central role in building the entire technical foundation of the product.
You’ll work hand-in-hand with the founding team, influence every technical decision, and ship product at high velocity — without bureaucracy or layers of approval.

This is a true 0→1 role where your work directly shapes the company’s architecture, standards, and long-term technical direction.

Your Responsibilities

Full-Stack Development

• Build fast, lightweight, and reliable front-end applications (React).

• Develop backend services powering conversational and AI-driven experiences.

Infrastructure & DevOps

• Design and maintain scalable cloud infrastructure (preferably GCP).

• Set up CI/CD pipelines, observability, monitoring, and infra-as-code.

• Optimize performance, reliability, and security across systems.

Architecture & Technical Excellence

• Own core architectural decisions and enforce best engineering practices.

• Ensure code quality, stability, and scalability from the ground up.

• Collaborate closely with early users and customers to iterate quickly.

Your Profile

Must-Have Experience

• Strong full-stack engineering background with a DevOps mindset.

• Hands-on expertise in cloud platforms (GCP ideal): deployments, infra, CI/CD.

• Proficient in TypeScript and Python.

• Experienced with React, Next.js, and FastAPI.

• Solid knowledge of PostgreSQL and Redis.

• Ability to design scalable systems and deliver production-grade code quickly.

• Comfortable using AI-assisted coding tools (Cursor, Claude Code, Copilot).

• Thrives in fast-moving, ambiguous, 0→1 environments.

• Fluent in English (French is a plus).

Why Join

• Be part of a company already demonstrating strong early traction and revenue.

• Work on the next fundamental shift in the web — agentic interfaces.

• Partner directly with experienced YC founders who have scaled product and tech before.

• Take ownership of mission-critical topics, grow at a rapid pace, and help define the future direction of the company.
