Software Engineer – Reinventing How the World Rents
role at
The Flex .
Our mission: make renting
borderless, instant, and intelligent . Through
Base360.ai , our proprietary platform, we’re building the
digital operating system of the rental world
— connecting property data, automating operations, and creating an intelligent infrastructure that powers every stay, everywhere.
What You’ll Build You’ll work on the core systems that make The Flex run — from seamless booking flows and payment infrastructure to automated cleaning logistics and smart pricing algorithms. You’ll turn complex, fragmented real estate operations into
clean, reliable, and intelligent software . Your work won’t live in the abstract — it’ll directly shape how thousands of people move, live, and experience flexibility.
Your Mission
Build the Core – Develop scalable, high-performance APIs and automation workflows that drive global operations.
Automate Everything – Design microservices and serverless functions that eliminate repetitive manual tasks.
Integrate the Ecosystem – Connect Base360.ai with partners like Airbnb, Stripe, and Twilio through clean, reliable integrations.
Design for Scale – Build fault‑tolerant, event‑driven systems that can handle millions of transactions in real time.
Collaborate Across Borders – Partner with product, data, and operations teams to bring automation to life in the physical world.
Ship Fast, Learn Faster – Iterate quickly, measure impact, and scale what works.
You’re a Great Fit If You Have
Strong experience with Node.js, React, and/or Python (FastAPI).
Familiarity with AWS (serverless stack) and API‑first architectures.
Experience with databases, microservices, and real‑time systems.
A builder’s mindset — fast, pragmatic, and obsessed with elegant solutions.
Curiosity about automation, AI, and real estate tech.
A bias for action — you move ideas to production, not slide decks.
Why You’ll Love It Here
Massive real‑world impact. Your code will power thousands of stays and automate operations across cities worldwide.
Global mission, lean team. No bureaucracy — just ambitious builders who move fast.
Autonomy & ownership. You’ll have freedom to make decisions and ship bold ideas.
Performance‑driven rewards. Competitive compensation + upside for top performers.
Remote‑first culture. Work from anywhere. What matters is output, not hours.
Do Not Apply If
You want predictable routines over progress.
You prefer planning to building.
You’re not aiming to be among the top 1% in your craft.
