About this role

oin the team redefining the future of global living.

At The Flex, we believe renting a home should feel instant, intelligent, and effortless β€” 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 β€” connecting property data, orchestrating operations, and enabling seamless stays across continents.

If you’re driven by technical ownership, system architecture, and building platforms that operate at real-world scale, this role puts you at the center of how millions of people move, live, and experience the world.

πŸ’‘ What You’ll Build

As a Lead Full-Stack Engineer, you will own the architecture and technical direction of The Flex platform β€” spanning web applications, APIs, automation engines, and cloud infrastructure.

You’ll lead by building.
You’ll design systems, set standards, and make key technical decisions while remaining deeply hands-on across the stack.

This is not a people-management role.
It’s a technical leadership role for someone who wants to shape systems, mentor by example, and build platforms that scale globally.

βš™οΈ Your Mission

Own the Architecture
Define and evolve the technical architecture powering bookings, payments, availability, pricing, and guest experience.

Lead by Building
Deliver critical features end-to-end across frontend, backend, and infrastructure β€” setting the bar for quality and speed.

Design API-First Platforms
Architect scalable, well-structured APIs that connect Base360.ai to internal tools and external partners.

Automate the Business
Build event-driven services and intelligent workflows that replace manual operations across the company.

Integrate at Scale
Own and evolve deep integrations with platforms such as Airbnb, Stripe, Hostaway, and Twilio.

Ship with Confidence
Deploy and operate serverless infrastructure on AWS, ensuring reliability, security, and global performance.

Solve the Hard Stuff
Lead solutions for real-time booking sync, pricing intelligence, keyless access logic, AI-powered alerts, and live operational dashboards.

Raise the Bar
Establish best practices, review critical code, and mentor engineers through example and technical clarity.

🧠 You’re a Great Fit If You Have

  • Strong senior-level experience with FastAPI, React, and AWS

  • Proven ownership of system architecture and complex distributed systems

  • Deep experience designing and scaling API-first platforms

  • A history of building production-grade systems used at real scale

  • High standards for code quality, reliability, and performance

  • A builder’s mindset β€” you execute fast, think long-term, and enjoy responsibility

🌍 Why You’ll Love Working Here

Architect Real Impact
Your decisions will shape a platform used across cities and continents.

High Ownership, No Politics
Small, elite team with real autonomy and zero corporate drag.

Build From First Principles
You’ll help define not just features, but the foundation of the company’s technology.

Performance-Based Rewards
Top-of-market compensation with meaningful upside for exceptional leaders.

Remote-First
Work from anywhere β€” we care about leverage and outcomes, not hours.

🚫 This Role Is Not for You If

  • You want a management-heavy role with little hands-on work

  • You avoid making hard technical decisions

  • You’re uncomfortable owning systems end-to-end

  • β€œGood enough” is acceptable to you
