The listing
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, 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 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.
