## Job description

At The Flex, we believe renting a home should be as simple 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 systems, and creating seamless experiences for guests, landlords, and operators worldwide.

We're looking for a Full-Stack Product Engineer who thrives at the intersection of product, engineering, and execution.

This isn't a role where you'll simply implement tickets.

You'll identify problems, design solutions, build products, automate workflows, and help shape the future of the platform.

## WHAT YOU'LL DO

## BUILD PRODUCTS END-TO-END

Take ideas from concept to production by designing, building, testing, and launching features that create measurable business impact.

## OWN CUSTOMER PROBLEMS

Work directly with founders and operational teams to understand challenges and transform them into elegant software solutions.

## MOVE FAST

Ship quickly, gather feedback, iterate, and continuously improve products based on real-world usage.

## CREATE AUTOMATION

Design systems that eliminate manual work and allow the company to scale efficiently.

## BUILD INTERNAL TOOLS

Develop operational dashboards, workflow engines, management platforms, and AI-powered tools used across the business.

## CONNECT EXTERNAL SYSTEMS

Build integrations with platforms such as Airbnb, Stripe, Hostaway, Twilio, Google, and OpenAI.

## LEVERAGE AI

Implement AI-powered features and workflows that improve productivity, decision-making, and customer experience.

## SCALE THE PLATFORM

Ensure systems remain reliable, secure, and scalable as the business grows internationally.

## TECH STACK

Current technologies include:

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

You don't need experience with every technology listed above, but you should be capable of learning quickly and adapting.

## WHAT WE'RE LOOKING FOR

## MUST-HAVE

- Strong full-stack development experience
- Experience building production-grade web applications
- Strong understanding of APIs and databases
- Product mindset and user-centric thinking
- Ability to work independently and take ownership
- Strong problem-solving skills
- Excellent written communication

## NICE-TO-HAVE

- Experience with FastAPI
- Experience with React and TypeScript
- Experience with AI tools or LLM integrations
- Startup experience
- PropTech, marketplace, or SaaS experience

## WHAT SUCCESS LOOKS LIKE

Within your first year:

- You've launched multiple high-impact features
- Manual operational processes have been automated
- Product development cycles are significantly faster
- AI-powered workflows have been deployed across the business
- Base360.ai http://Base360.ai has become a stronger competitive advantage for The Flex

## WHY JOIN THE FLEX

## MASSIVE OWNERSHIP

You'll have direct influence over product decisions, architecture, and company strategy.

## BUILD REAL PRODUCTS

Your work will impact thousands of users and properties across multiple countries.

## LEARN AT STARTUP SPEED

You'll work closely with founders and gain exposure to engineering, product, operations, AI, and business.

## REMOTE-FIRST

Work from anywhere.

## HIGH GROWTH ENVIRONMENT

We're building quickly and looking for people who want to grow alongside the company.

## THIS ROLE IS NOT FOR YOU IF

- You prefer highly structured corporate environments
- You only want to write code from predefined specifications
- You avoid ownership outside your immediate responsibilities
- You are uncomfortable moving quickly and adapting to change

If you love building products, solving real-world problems, and creating systems that scale, we'd love to hear from you.

## Core Business
- **Primary industry**: Real Estate / Flexible Living / Property Management
- **Target customers**: B2B (150+ corporate partners for employee relocation, staffing, insurance claims), B2C (tenants seeking flexible leases), and B2B (landlords seeking guaranteed rent with zero voids)
- **Mission statement**: To eliminate the constraints of traditional rental models, reimagining the idea of 'home' from something fixed to something flexible—unlocking freedom for renters, efficiency for landlords, and growth for entire cities.

## Products & Services
- **Flexible Rentals (Tenants)**: Fully furnished, hotel-grade homes with digital key access, utilities, Wi-Fi, optional housekeeping, and 24/7 live support. Leases as short as a week or as long as needed, with month-to-month terms, easy extensions, and exits.
- **Guaranteed Rent (Landlords)**: Fixed monthly payments with zero voids from day one; The Flex handles upgrades, dynamic pricing, resident vetting, cleaning, and maintenance.
- **Corporate Housing (B2B)**: One master lease unlocks an entire portfolio across cities; dedicated account manager; ideal for employee relocation, project teams, and insurance claims.

## Market Standing
- **Valuation**: Not publicly available
- **Key Metric**: 47 employees (as of mid-2025) with monthly headcount growth of +4.9%; 500+ active job postings; 84,000+ LinkedIn followers; over 150 corporate partners; properties in multiple cities across the UK, France, Algeria, and recently launched in Lisbon.
- **Notable Investors/Partners**: 150+ corporate clients; no external funding rounds publicly disclosed (appears bootstrapped or early-stage without major VC backing).
- **Growth Signals**: Rapid headcount growth (+4.9% monthly), recent expansion into Lisbon (July 2025), 500+ open roles, and a goal of reaching properties in every major city worldwide by 2027.

## Competitive Advantages
- **Flexibility at scale**: Month-to-month leases, same-day move-ins, cross-border relocation with a few taps—unlike traditional long-term leases.
- **Full-stack property management**: Landlords get guaranteed rent and zero voids, while tenants get hotel-grade service (cleaning, maintenance, 24/7 support).
- **Data-driven operations**: Evidence-based decision-making, dynamic pricing, and rapid evaluations for landlords.
- **Flat, ego-free culture**: No hierarchy or bureaucracy; best idea wins based on data, not tenure.

## Strategic Focus
- **Global expansion**: Actively entering new cities (Lisbon launched July 2025) with a target of having homes in every major city worldwide.
- **Scaling the platform**: Growing the portfolio of properties and corporate partnerships; hiring aggressively (500+ open roles) to support expansion.
- **Product innovation**: Building a seamless, Amazon-like rental experience with instant approvals, digital keys, and flexible terms.

## Why Work Here
- **Culture**: Ego-free, fast-paced, values-driven environment with no hierarchy or bureaucracy. Emphasis on big ideas, learning from failure, and shipping fast.
- **Remote-first**: The Flex is a remote-first company, hiring stellar talent globally and trusting them to own outcomes.
- **Mentorship & growth**: Work alongside senior leaders (including founders) who provide direct feedback, hands-on coaching, and clear career progression. Promotions based on performance, not tenure.

- **Innovation**: Data-backed approach; open-minded, diverse team driving solutions.
- **Notable perks**: Minimal rules, total accountability, genuine freedom; "Career Rocket Ship" where you own mission-critical projects from day one.
