Senior Full Stack Software Engineer

The Flex is looking for a senior full stack software engineer to design scalable systems, solve complex problems, and build products with real‑world impact.

Help build the future of global living at The Flex, where renting should be instant, intelligent, and effortless – as simple as tapping a button. Our mission is ambitious : to make living anywhere in the world frictionless.

Powered by Base360.ai, the automation‑first platform, we’re creating the operating system for modern rentals – unifying property data, streamlining operations, and powering intelligent systems behind every stay in every city.

We’re searching for a Senior Software Engineer who loves designing scalable systems, solving complex problems, and building products with real‑world impact. If you’re motivated by architecture, automation, and global‑scale engineering challenges, this is your opportunity to reshape how millions move and live.

What You’ll Build

You’ll engineer the foundations of the Flex platform – the services, APIs, and automation engines that keep our global rental network running smoothly.

From backend systems and data pipelines to cloud infrastructure and integration layers, your work will ensure our platform is fast, resilient, and intelligent.

You’ll partner with product, operations, and data to engineer clarity in an industry known for complexity – transforming messy real‑world logistics into clean, automated workflows.

Your Mission

• Build the Backbone – Architect and deliver scalable services that power bookings, payments, availability, and end‑to‑end operations.
• Engineer Automation – Develop intelligent microservices and serverless workflows that eliminate manual processes across teams and cities.
• Scale Globally – Design systems capable of handling large volumes of transactions, events, and real‑time updates with reliability.
• Connect the Ecosystem – Build and maintain integrations between Base360.ai and key partners like Airbnb, Stripe, Twilio, and Hostaway.
• Enhance Machine Intelligence – Work closely with AI engineers to apply predictive logic, automation, and adaptability into core systems.
• Lead Through Craft – Mentor teammates, drive engineering standards, and raise the technical bar with thoughtful code reviews and guidance.
