Overview
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.
What You Bring
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.
Why You’ll Love It Here
Build global impact: Your code will power thousands of stays and automate entire property operations.
Move fast, build smart: Small team, no bureaucracy, full autonomy.
Performance-based rewards: Competitive compensation + growth incentives.
Learn from the best: Work directly with high-performing founders and engineers.
Remote-first freedom: Work from anywhere — results > hours.
Don’t Apply If
You want a slow, predictable 9–5 job.
You thrive on gossip or politics.
You’re not hungry to grow or improve.
You’re okay with being “good enough” — we’re building with the best.
The Flex x Base360.ai We’re not just writing backend code — we’re building the
AI-powered operating system for the rental world.
