## Job description

At The Flex, we believe renting a home should be as effortless as booking a ride.

Our mission is to enable anyone to live anywhere, anytime, without friction.

Powered by Base360.ai http://Base360.ai, our proprietary technology platform, we are building the operating system for modern renting—automating operations, connecting fragmented systems, and creating seamless experiences for guests, landlords, and operators across the world.

We're looking for a Full-Stack Engineering Lead to help scale both our technology and our engineering culture.

This is a hands-on leadership role. You'll spend the majority of your time building products, solving technical challenges, and architecting systems while also helping guide engineering standards, mentoring team members, and shaping the future of the platform.

If you're excited about ownership, rapid execution, AI, automation, and building products that have real-world impact, we'd love to meet you.

## WHAT YOU'LL BUILD

As a Full-Stack Engineering Lead, you'll lead the development of Base360.ai http://Base360.ai, the technology platform powering every aspect of The Flex.

You'll work across product, engineering, AI, and operations to create scalable systems that automate processes, improve decision-making, and accelerate company growth.

You'll be responsible not only for what gets built, but how it's built.

## YOUR MISSION

## LEAD PRODUCT DEVELOPMENT

Design, build, and launch high-impact products that improve guest experience, operational efficiency, and business performance.

## ARCHITECT SCALABLE SYSTEMS

Make key technical decisions that ensure the platform remains scalable, reliable, and maintainable as the company grows internationally.

## DRIVE ENGINEERING EXCELLENCE

Establish engineering best practices, code quality standards, development workflows, and technical documentation.

## MENTOR AND SUPPORT ENGINEERS

Provide technical guidance, conduct code reviews, and help create a high-performance engineering culture focused on continuous improvement.

## BUILD AUTOMATION AT SCALE

Develop systems that eliminate manual work and allow operations to scale efficiently across multiple markets.

## INTEGRATE CRITICAL PLATFORMS

Build and maintain integrations with platforms including Airbnb, Hostaway, Stripe, Twilio, Google, OpenAI, and other strategic partners.

## LEVERAGE AI

Implement AI-powered workflows, tools, and agents that improve productivity and decision-making across the business.

## COLLABORATE ACROSS TEAMS

Work closely with product, operations, revenue, and leadership teams to translate business challenges into scalable technical solutions.

## TECH STACK

Our current stack includes:

- Python
- FastAPI
- React
- TypeScript
- Supabase
- PostgreSQL
- AWS
- OpenAI APIs
- Stripe
- Twilio
- Docker
- GitHub Actions

You don't need experience with every technology listed, but you should be comfortable learning quickly and leading technical decisions.

## WHAT WE'RE LOOKING FOR

## MUST HAVE

- Strong full-stack software engineering experience
- Experience designing and scaling production systems
- Strong understanding of APIs, databases, cloud infrastructure, and system architecture
- Experience leading technical projects from concept to deployment
- Excellent problem-solving and communication skills
- Ability to balance speed with engineering quality
- Strong ownership mentality and bias toward execution

## BONUS POINTS

- Experience leading engineers or technical teams
- Startup or scale-up experience
- Experience with AI products or LLM integrations
- Experience with SaaS, marketplace, travel, or PropTech businesses
- Experience with FastAPI, React, AWS, or Supabase

## WHAT SUCCESS LOOKS LIKE

Within your first year:

- Core systems become more scalable, reliable, and automated
- Engineering velocity increases significantly
- Technical debt is reduced without slowing innovation
- AI-powered workflows are deployed across the business
- New products are launched rapidly and effectively
- Base360.ai http://Base360.ai becomes a major competitive advantage for The Flex

## WHY JOIN THE FLEX

## REAL OWNERSHIP

You'll have direct influence over technology strategy, architecture, and product direction.

## BUILD AT SCALE

Your work will power thousands of stays across multiple countries.

## LEAD BY BUILDING

This is a hands-on role where you'll spend your time creating solutions, not sitting in meetings.

## SMALL TEAM, MASSIVE OPPORTUNITY

Work closely with founders and help shape the future of both the platform and the engineering organization.

## PERFORMANCE-BASED REWARDS

Competitive compensation with meaningful upside for exceptional performers.

## REMOTE-FIRST

Work from anywhere. We care about impact, not hours worked.

## THIS ROLE IS NOT FOR YOU IF

- You prefer large corporate environments with rigid processes
- You enjoy managing more than building
- You are uncomfortable making decisions with incomplete information
- You require detailed instructions for every task
- You are unwilling to take ownership beyond your immediate responsibilities

If you're excited about leading by example, building world-class software, and helping create the operating system for modern renting, we'd love to hear from you.
