Founding Engineer

Join the team redefining the future of global living — from the ground up.

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.

This is not a job where you “pick up tickets.”
This is a chance to build a company’s technical foundation and define how a global platform operates at scale.

What You’ll Build

As a Founding Engineer, you will help design, build, and scale the core technology that The Flex is built on — from first principles.

You’ll work across product, engineering, and operations, owning systems end-to-end: web apps, APIs, automation pipelines, integrations, and cloud infrastructure.

You’ll make architectural decisions early — the kind that matter for years — and move fast to turn ideas into production systems used in the real world.

If you enjoy ambiguity, ownership, and building things that actually ship, this role is for you.

️ Your Mission

Build from Zero to One
Design and implement the initial architecture powering bookings, payments, availability, and guest experience.

Own the Stack
Build across frontend, backend, APIs, and cloud infrastructure — choosing tools and patterns that scale.

Automate the Business
Replace manual processes with event-driven workflows and intelligent automation from day one.

Integrate the Ecosystem
Build deep integrations with platforms such as Airbnb, Stripe, Hostaway, and Twilio.

Ship Relentlessly
Deploy, monitor, and iterate on production systems with speed, reliability, and pragmatism.

Solve Real-World Problems
Tackle real-time booking sync, pricing intelligence, keyless access logic, AI-powered alerts, and operational dashboards.

Set the Technical DNA
Establish engineering standards, best practices, and a culture of quality, ownership, and execution.

You’re a Great Fit If You Have

• Strong experience building production systems (full-stack or backend-heavy)

• Comfort working across web apps, APIs, and cloud infrastructure

• Experience with Node.js, React, and AWS (or equivalent stacks)

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

• A bias toward shipping over perfection

• High tolerance for ambiguity and changing requirements

• An ownership mindset — you treat the product like it’s yours

Why You’ll Love Working Here

Foundational Impact
Your work will define how the company operates for years to come.

Extreme Ownership
You won’t just influence decisions — you’ll make them.

Fast Feedback Loop
What you build goes live, gets used, and evolves quickly.

Meaningful Upside
Competitive compensation with strong upside aligned to long-term success.

Remote-First
Work from anywhere — autonomy and trust are core to how we operate.

This Role Is Not for You If

• You want well-defined requirements and rigid processes

• You avoid responsibility for production systems

• You prefer specialization over ownership

• You’re optimizing for comfort instead of impact
