Job description

Rebuild the backbone of modern renting.

At The Flex, we believe renting a home should be instant, intelligent, and seamless — as easy as tapping a button. Our ambition is bold: create a world where anyone can live anywhere without friction.

Powered by Base360.ai, our automation and intelligence platform, we’re building the operating system for global stays — syncing property data, orchestrating operations, and powering the infrastructure behind every effortless guest experience.

We’re hiring a Backend Engineer who loves building automation, scaling systems, and solving real-world problems with clean, resilient software.

What You’ll Build

As a Backend Engineer, you’ll architect the foundations of The Flex: the systems, APIs, and automation layers that coordinate global inventory, sync bookings in real time, and enable properties to operate autonomously.

Your work will blend digital automation with real-world logistics — enabling thousands of stays to run smoothly without manual intervention.

⚙️ Your Mission

• Build the Core — Design and scale robust APIs and backend services that manage bookings, payments, availability, and property intelligence.
• Automate the Workflows — Develop serverless functions and microservices that eliminate repetitive tasks and streamline operations across cities and continents.
• Connect the Ecosystem — Implement integrations between Base360.ai and major platforms such as Airbnb, Stripe, Twilio, and Hostaway.
• Engineer for Scale — Architect event-driven systems and data pipelines capable of handling millions of events and transactions reliably.
• Power Intelligence — Work with AI and data teams to embed smart automation and predictive logic into operational flows.
• Collaborate Closely — Partner with product, front-end, and operations teams to translate messy real-world challenges into simple, scalable backend solutions.

You’ll Excel in This Role If You Have

• Expertise with Node.js, Python/FastAPI, and AWS serverless.
• Strong experience building and scaling API-first products.
• A deep understanding of databases, synchronization logic, and distributed systems.
• A passion for automation, intelligent operations, and emerging PropTech.
• A systems-level mindset — you think in terms of resilience, reliability, and flow.
• A strong bias toward execution and ownership.

Why You’ll Love Working Here

Meaningful Impact — Your systems will become the automation engine of thousands of stays across multiple countries.

High Ownership — Small team, no bureaucracy, and the opportunity to influence core architectural decisions.

Speed & Autonomy — Move fast, ship often, and help define the future of our technical ecosystem.

Performance-Based Rewards — Competitive salary + meaningful equity opportunities for top performers.

Fully Remote — Work from anywhere. What matters is excellence, not timesheets.

This Role Is Not for You If

• You want slow, predictable routines.
• You prefer planning meetings over shipping code.
• You’re content writing average software.
• You’re not committed to becoming world-class in your craft.
