Lead Full-Stack Engineer

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 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.

What You’ll Build

As a Lead Full-Stack Engineer, you will own the architecture and technical direction of The Flex platform — 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.

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 — 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.

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 — we care about leverage and outcomes, not hours.

You’re a Great Fit If You Have

  • Strong senior-level experience with Node.js, React, and AWS (serverless)
  • Proven ownership of system architecture and complex distributed systems
  • Deep experience designing and scaling API-first platforms
  • Experience with Python / FastAPI for automation or data services (bonus)
  • A history of building production-grade systems used at real scale
  • High standards for code quality, reliability, and performance
  • A builder’s mindset — you execute fast, think long-term, and enjoy responsibility

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
  • “Good enough” is acceptable to you
