Job description

Join the team redefining the future of global living.

At The Flex, we believe renting a home should feel instant, intelligent, and effortless — as seamless as booking a ride.
Our ambition is bold: enabling anyone to live anywhere, anytime, without friction.

Powered by Base360.ai , our proprietary automation engine, we’re building the operating system for modern renting — connecting property data, orchestrating operations, and enabling seamless stays across continents.

If you’re motivated by complex systems, automation, and building software that operates in the real world, this role gives you the ownership and scope to make a visible, lasting impact.

What You’ll Build

As a Senior Software Engineer, you’ll design, build, and scale critical parts of The Flex platform — from core services and APIs to automation workflows and real-time systems.

You’ll operate with high autonomy, owning problems end-to-end and contributing directly to architectural decisions, while staying deeply hands-on with production code.

This role is for engineers who want impact, not meetings — and who take pride in building systems that are reliable, elegant, and scalable.

⚙️ Your Mission

Build Core Systems
Develop and maintain scalable services that power bookings, payments, availability, pricing, and guest experience.

Design Robust APIs
Create clean, well-structured APIs that connect Base360.ai with internal tools and external partners.

Automate Operations
Build event-driven workflows that eliminate manual processes and unlock operational leverage.

Ship with Confidence
Deploy and operate cloud-native infrastructure on AWS with a focus on reliability, security, and performance.

Solve Meaningful Problems
Work on real-time booking synchronization, pricing intelligence, keyless access logic, AI-powered alerts, and live operational dashboards.

Collaborate for Impact
Work closely with product, data, and operations teams to turn complex requirements into simple, effective systems.

You’re a Great Fit If You Have

• Strong experience building production systems with Node.js, React, and AWS

• A solid understanding of distributed systems and API-first design

• Experience with Python / FastAPI for automation or data services (bonus)

• A track record of shipping clean, maintainable, scalable code

• Comfort owning features and systems from design to production

• Curiosity about automation, AI-driven operations, and proptech

• A bias toward execution — you deliver, iterate, and improve continuously

Why You’ll Love Working Here

Visible Impact
Your work will directly affect thousands of stays and real-world operations.

Autonomy & Trust
You’ll own systems and decisions without unnecessary process or micromanagement.

Fast Growth Environment
We move quickly, learn constantly, and value technical excellence.

Performance-Based Rewards
Competitive compensation with upside for high performers.

Remote-First
Work from anywhere — outcomes matter more than hours.

This Role Is Not for You If

• You want a narrowly scoped role with limited ownership

• You avoid production responsibility

• You’re uncomfortable working in fast-moving environments

• “Good enough” is your standard
