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.
This role is ideal for someone who thrives in a fast-paced, high-impact startup environment, takes full ownership of projects, and is passionate about shaping the future of living.
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.
Experience building cloud-native/serverless applications.
Solid understanding of REST API design and integrations.
Familiarity with FastAPI and Python is a strong plus.
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.
Why Join The Flex?
Be part of a tech-first company revolutionizing the rental industry with our proprietary PMS.
Shape the core tech stack from the ground up.
Competitive salary + performance-based incentives.
Remote-first culture with high autonomy and ownership.
Real opportunity to grow into a leadership role as we scale globally.
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.
