At The Flex, we’re on a mission to make renting as effortless as buying something online.
We’re creating a world where anyone can rent anywhere, instantly — and where landlords can manage their properties seamlessly, without agents, inefficiency, or high fees.
Through Base360.ai, our proprietary operating platform, we’re powering the next evolution of real estate — intelligent, automated, and borderless.
We’re assembling a lean team of world-class engineers ready to scale The Flex into a global powerhouse. If you want to build systems that run cities, automate operations, and change how people live — you’re in the right place.
🧠 What You’Ll Build
- As a Backend Engineer, you’ll design and scale the systems that power The Flex — from reservation logic and payments to property automation and data intelligence.
- You’ll focus on building high-performance APIs, serverless architectures, and automation pipelines that make our platform faster, smarter, and more reliable every day.
🔧 What You’Ll Do
- API Architecture: Design and optimize scalable APIs connecting booking platforms, payment processors, and internal systems.
- Automation at Scale: Build tools to automate critical workflows — check-ins, check-outs, messaging, and reporting.
- System Design: Develop resilient, serverless infrastructure that supports global rental operations.
- Data Reliability: Maintain data accuracy and system integrity across integrations.
- Problem Solving: Diagnose and fix complex backend issues quickly and efficiently.
- Cross-Functional Collaboration: Work closely with product and operations teams to bring real-world needs into technical reality.
- Code Quality: Write clean, testable, and maintainable code supported by CI/CD best practices.
- Strong proficiency in Node.js and cloud platforms (AWS preferred).
- Deep understanding of API design, scalability, and distributed systems.
- Experience with serverless architecture (Lambda, DynamoDB, etc.).
- Familiarity with FastAPI, Python, or scripting (bonus).
- Experience in automation systems (real estate, travel, or rentals is a plus).
- Strong problem-solving skills, curiosity, and a bias toward action.
- Build global impact: Your code will power thousands of stays and automate entire property operations.
