Backend Engineer Remote

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.
