Reinvent How The World Rents. At
Reinvent How The World Rents. At The Flex, we believe renting a home should feel as effortless as ordering an Uber.
Our mission is to make renting borderless, instant, and intelligent.
Through Base360.ai, our proprietary platform, we’re building the digital nervous system of the rental world — connecting property data, automating operations, and creating an intelligent infrastructure that powers every stay, everywhere.
We’re looking for a Backend Engineer who thrives on automation, scalability, and impact — someone who can turn complex operational systems into elegant, self-sustaining software.
💡 What You’ll Build
As a Backend Engineer, you’ll design and scale the backbone of The Flex — the APIs, automations, and intelligence layers that connect global booking channels, automate real-world logistics, and power predictive insights across cities.
Your work will make the difference between chaos and flow — enabling thousands of stays to happen seamlessly, without human intervention.
Your Mission
- Architect Core Systems – Build scalable, high-performance APIs and services that power global bookings, payments, and property data synchronization.
- Automate Operations – Create microservices and serverless functions that eliminate repetitive manual processes.
- Integrate Intelligently – Connect Base360.ai to platforms like Airbnb, Stripe, Twilio, and Hostaway.
- Design for Scale – Build fault-tolerant systems and data pipelines capable of handling millions of transactions across borders.
- Enhance Intelligence – Work with AI and data teams to embed predictive automation into everyday workflows.
- Collaborate for Impact – Partner with product, operations, and front-end teams to translate complex real-world problems into clean, scalable backend solutions.
You’re a Great Fit If You Have
- Strong skills in Node.js, Python (FastAPI), and AWS (serverless stack preferred).
- Experience designing and scaling API-first architectures.
- Deep understanding of databases, data synchronization, and event-driven systems.
- Curiosity about automation, real estate tech, and AI-powered operations.
- A “systems thinker” mindset — building for resilience, not just function.
- A bias for action, and comfort working in a fast-moving, high-accountability environment.
Why You’ll Love It Here
- Massive impact. Your systems will power thousands of stays and automate the backbone of a $4T industry.
- Global mission, lean team. No bureaucracy. No silos. Just high performers shipping fast.
- Autonomy & growth. You’ll own projects end-to-end and help shape our technical roadmap.
- Performance-driven rewards. Competitive compensation + upside for exceptional contributors.
- Remote-first culture. Work from anywhere — we care about results, not hours.
Do Not Apply If
- You’re looking for a slow, risk-free 9–5.
- You prefer meetings over momentum.
- You’re satisfied with average code and average results.
- You don’t want to push yourself to operate at the top 1% of your craft.
