Paris, Île-de-France The Flex Temps plein

Join the team redefining the future of global living.

At The Flex, we believe renting a home should feel instant, intelligent, and effortless — the same simplicity as booking a ride.
Our ambition is bold: a world where anyone can live anywhere, anytime, without friction.

Powered by , our proprietary automation engine, we're building the operating system for modern renting — connecting property data, orchestrating operations, and enabling seamless stays across continents.

If you're energized by automation, AI, and large-scale real-world systems, this is your chance to help shape how millions move, live, and experience the world.

What You'll Build

As a Full-Stack Software Engineer, you'll design and scale the core technology behind The Flex — powering instant bookings, intelligent access, automated workflows, and predictive operations.

You'll work across frontend, backend, and cloud infrastructure, transforming complex operational challenges into elegant, scalable systems.

You won't just ship features.
You'll create leverage, unlock automation, and architect the foundation of tomorrow's intelligent rental ecosystem.

Your Mission

Build the Engine
Develop fast, reliable, and scalable applications that power bookings, payments, availability, and guest experience.

Automate at Scale

Launch & Iterate Fast

Solve Hard Problems
Tackle real-time booking sync, pricing intelligence, keyless access logic, AI-powered alerts, and live operational dashboards.

Build With the Team
Collaborate closely with product, data, and operations to turn automation ideas into real-world impact.

You're a Great Fit If You Have

  • Strong experience with , React, and AWS (serverless)

  • A deep understanding of API-first architectures and distributed systems

  • Experience with Python/FastAPI for scripting, automation, or data services (bonus)

  • A track record of building clean, scalable, production-ready systems

  • Curiosity about automation, AI-driven operations, and property technology

  • A bias toward execution — you ship fast, learn quickly, and enjoy solving complex problems

Why You'll Love Working Here

Build Real Impact
Your code will shape thousands of stays and redefine a multi-trillion-dollar industry.

Small Team, Big Mission
High ownership, zero bureaucracy, and the chance to build foundational systems from scratch.

Learning & Growth
We move fast, iterate constantly, and value continuous improvement.

Performance-Based Rewards
Competitive compensation + meaningful upside for exceptional talent.

Remote-First
Work from anywhere — we care about outcomes, not hours.
