Backend Engineer – Full-time

Reinvent how the world rents.

At The Flex, we believe renting a home should be as effortless as ordering an Uber.
Our mission: 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 the 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 real-world 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 platforms, power predictive insights, and orchestrate real-world logistics.

Your work will bridge digital intelligence and physical operations — enabling thousands of seamless stays to happen automatically, without human intervention.

⚙️ Your Mission

• Architect Core Systems – Build scalable, high-performance APIs and backend services that drive global bookings, payments, and property data synchronization.

• Automate Operations – Create microservices and serverless functions that remove repetitive manual processes and enhance efficiency.

• Integrate Intelligently – Connect Base360.ai with platforms like Airbnb, Stripe, Twilio, and Hostaway through robust, maintainable integrations.

• Design for Scale – Build fault-tolerant, event-driven systems and data pipelines capable of handling millions of transactions across borders.

• Enhance Intelligence – Collaborate with AI and data teams to embed predictive automation into operational workflows.

• Collaborate for Impact – Partner with product, operations, and front-end teams to turn complex real-world challenges into clean, scalable backend solutions.

You’re a Great Fit If You Have

• Strong experience with Node.js, Python (FastAPI), and AWS (serverless stack preferred).

• Proven track record designing and scaling API-first architectures.

• Deep understanding of databases, data synchronization, and event-driven systems.

• Curiosity for automation, AI, and real estate technology.

• A systems thinker mindset — you design for resilience, not just function.

• A bias for action — you thrive in fast-moving, high-accountability environments.

Why You’ll Love It Here

• Massive Impact – Your systems will power thousands of stays and automate the backbone of a $4T global industry.

• Global Mission, Lean Team – No bureaucracy. No silos. Just high performers moving fast.

• Autonomy & Growth – Own projects end-to-end and shape our technical roadmap.

• Performance-Driven Rewards – Competitive compensation and meaningful upside for top contributors.

• Remote-First Culture – Work from anywhere. We care about output, not office hours.

Do Not Apply If

• You’re looking for a slow, predictable 9–5.

• You prefer meetings over momentum.

• You’re satisfied with average code and average results.

• You’re not striving to operate in the top 1% of your craft.
