About The Flex

The Flex is on a mission to transform the rental sector globally. Renting a home should be as simple as buying an item on Amazon: seamless, borderless, and transparent. We’re making that a reality—building a next-generation Property Management System (PMS) that powers everything from tenant bookings to landlord operations, enabling effortless renting and hassle-free property management at scale.

We are assembling a small, dynamic team of A-Players who want to build category-defining products and scale The Flex into a global powerhouse. We reward ambition, promote from within, and create an environment where talent thrives.

Position Summary – Full Stack Engineer

As a Full Stack Engineer at The Flex, you will play a pivotal role in building our proprietary PMS—the backbone of our global rental platform. This is not just about writing code; it’s about designing and scaling the digital infrastructure that powers thousands of homes worldwide.

You’ll work across the full stack—front-end, back-end, and cloud—bringing bold ideas from concept to production. If you’re excited about solving complex challenges in real estate technology, pushing the boundaries of automation, and building systems that scale globally, this is the role for you.

Key Responsibilities

• Full-Stack Development – Design, develop, and maintain scalable web applications that form the core of our PMS, using Node.js, React, and modern frameworks.
• API-First Architecture – Build and optimize RESTful APIs (FastAPI/Node.js) that connect reservations, operations, and customer experiences into one seamless ecosystem.
• Automation & Intelligence – Develop automation tools that streamline operations, optimize pricing, and reduce human intervention in property management.
• Cloud Infrastructure – Deploy, manage, and scale applications on AWS, leveraging serverless and cloud-native best practices.
• Testing & Quality – Implement CI/CD pipelines, automated tests, and code reviews to ensure high reliability.
• Troubleshooting & Debugging – Rapidly investigate and resolve production issues.
• Cross-Functional Collaboration – Work hand-in-hand with product, design, and operations teams to build features that deliver real business impact.
  
  

What We’re Looking For

• Strong proficiency in Node.js, React, and AWS Cloud.

• Strong grasp of CI/CD, automated testing, and Git workflows.
• A problem-solver who learns quickly and thrives on autonomy.
• Excellent communicator and team player.
• Relentless drive to build world-class products.

You Should Not Apply If

• You are looking for a traditional corporate 9-to-5 job.
• You prefer office politics and gossip over problem-solving.
• You want a slow, predictable, dead-end role.
• You do not aim to be world-class at what you do.
