Job Specifications

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 Base360.ai, 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

Design microservices and AI-driven workflows that replace manual tasks across the business.

Connect the Ecosystem

Architect high-impact integrations between Base360.ai and partners such as Airbnb, Stripe, Hostaway, and Twilio.

Launch & Iterate Fast

Deploy and manage serverless infrastructure (AWS) with a relentless focus on speed, reliability, and global scale.

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 Node.js, 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.

This Role Is Not for You If

You want a slow, predictable 9–5
You prefer planning over building
“Good enough” is good enough
You’re not committed to becoming elite in your craft

About the Company

At The Flex, we believe renting a home should be as easy as buying an item from Amazon, that means ensuring our guests have an abundance of choice and flexibility to cancel if their plans change. We aim to help landlords stop paying excessive management fees and help renters live and work comfortably anywhere in the world. Know more
