Senior Fullstack Engineer - freelance

Budget: 600 - 800

Legacy ERP systems are stuck in the past.

SAP, Odoo, NetSuite, they still rely on assumptions from the early 2000s. We're building what comes next: an AI-native ERP that’s autonomous, agent-driven, and composable by design. Built for the real-world needs of mid-sized companies such as wholesalers and B2B brands.

Backed by €3M from top-tier investors (Daphni, Ovni, Motier) and experienced operators (Pennylane, Studapart), we’re moving fast from zero to one.

What You'll Build With Us

• Product features used daily by professionals. Built in React, TypeScript and Python
• A clean frontend UX: responsive, accessible, fast, and reactive to real-time data
• Backend APIs that are clean, consistent and performant using Django (django-ninja) and Pydantic
• A database model optimized for complex workflows, high-frequency queries and AI interfacing
• Observability of the features you own.
• Foundations for AI-native interfaces (RAG, agents, orchestration logic) woven into the product layer, not bolted on

What You Bring

• Expertise in python web backend development (Django optional)
• Strong frontend engineering skills with React and TypeScript
• Deep knowledge of API design, data modeling and query optimization
• Understanding of monitoring, observability and debugging in production
• Familiarity with distributed systems and asynchronous data flows
• Experience building responsive, accessible UIs
• Git proficiency and comfort in modern CI/CD pipelines

Why this matters

You’ll help invent a new category of enterprise software. This is not just another CRUD app, we’re building real-time orchestration engines, intelligent agents, and proactive interfaces. This is foundational work, built by a small, highly skilled team.

The team you’ll join

• Eugène: CTO + Former staff engineer at GitGuardian (Centrale Paris)
• Eric: CEO + Former lead product at GitGuardian (Centrale Paris)
• Max-Pol: Data scientist and software engineer (Centrale Paris)
• Rémi: Software engineer and ex-founder (Harvard)
• Florian: CRO + Former CRO of a scale-up (ESCP), working closely with our customers

This is a freelance role with the potential to transition into a full-time position. If you're excited about building the next generation of enterprise software from the ground up, we’d love to hear from you.
