Founding Engineer

🚀 Founding Engineer – Help Build the Next AI Powerhouse

Location: Paris (Hybrid – 2 days remote/week)

Contract: Full-time / Permanent

Language Requirements: Fluent French + Professional English

Join a fast-growing French AI scale-up, backed by top-tier investors, as a Founding Engineer and play a pivotal role in building the technical foundation of the company’s product and infrastructure.

This is more than just a technical role — it’s a unique opportunity to build the architecture, shape the product, and define the culture of a company poised to become a major player in European AI.

🧠 About the Company

The company has reached a key inflection point: strong product-market fit, growing customer base, and a clear roadmap toward international scaling.

• Team today: 12 people
• Target by year-end: 25+
• Structured into 3 squads:

• Software Engineering
• Artificial Intelligence (R&D and applied)
• Product & Design

You’ll be at the heart of product development, working hand-in-hand with both technical and business leaders.

🛠 Tech Stack

You’ll join a high-performance engineering environment working with modern, scalable technologies:

• Frontend: React, TypeScript
• Backend: Node.js, NestJS
• Additional language: Python (for AI integration & tooling)
• Database: PostgreSQL
• APIs: GraphQL via Hasura

We’re building a modular, API-first platform designed to scale — your architectural decisions will directly influence its evolution.

🔍 What We're Looking For

We’re seeking an experienced engineer who thrives in early-stage environments and wants to own the build — not just code.

Must-have qualifications:

• 5–10 years of experience in demanding tech environments (scale-ups, SaaS startups, product-driven companies)
• Strong architectural skills and clean software engineering practices
• End-to-end product mindset: you understand the why behind what you build
• Solid experience with backend and fullstack architecture (Node, Python, TypeScript)
• Engineering degree (or equivalent strong technical background)
• Fluent in French and comfortable with English in a professional context

Nice-to-have:

• Past experience in AI/ML environments or working closely with Data/AI teams
• Familiarity with DevOps / CI/CD / cloud infra (AWS, GCP…)

🌍 Work Environment

• Based in Paris in our Tech & R&D Hub
• Hybrid model: 2 remote days/week
• Dynamic, transparent, product-focused culture
• Flat hierarchy, fast decision cycles, high ownership

🧪 Recruitment Process

We believe great people don't need 8 rounds of interviews.

Our process is fast and simple:

1. 45-min conversation with one of the Co-Founders
2. 60-min deep dive with the Tech team (code + system thinking)

That’s it. No take-home test. No bureaucracy. Just people talking tech and vision.

✅ Why Join?

• Ownership & Impact: You'll shape both product and tech foundations from the ground up
• Mission-Driven: Work on cutting-edge AI challenges that matter
• Top Talent: Collaborate with passionate engineers, researchers, and product minds
• Trajectory: Strong funding, clear vision, ambitious growth — we’re just getting started
