Senior Product Engineer

The Flex
Lithuania · Full-time · Mid-Senior

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 love building products end-to-end, obsess over user experience, and enjoy owning real systems used in the real world, this role is for you.

💡 What You’ll Build

As a Senior Product Engineer, you’ll sit at the intersection of product, engineering, and operations.

You’ll own features from idea to production — shaping the product, designing the system, writing the code, and shipping improvements that directly impact guests, operators, and partners.

This is a role for engineers who think in products, not tickets, and who care deeply about usability, performance, and outcomes.

⚙️ Your Mission

Own Product Features End-to-End

Design, build, and evolve core product experiences across web applications and APIs.

Build for Users

Translate real operational and user problems into simple, intuitive product solutions.

Ship Fast, Learn Faster

Release frequently, gather feedback, and iterate relentlessly.

Design Scalable Systems

Build clean, maintainable architectures that scale as the platform grows.

Automate The Experience

Use automation and intelligent workflows to remove friction from both guest and operator journeys.

Collaborate Closely

Work hand-in-hand with product, design, data, and operations to turn ideas into impact.

🧠 You’re a Great Fit If You Have

  • Strong experience building user-facing products as a senior engineer
  • Comfort working across frontend, backend, and APIs
  • Experience with modern web stacks (React, Node.js, cloud-native platforms)
  • A strong product mindset — you care why something is built, not just how
  • A history of shipping features that users actually love
  • High standards for quality, performance, and UX
  • A bias toward execution and ownership

🌍 Why You’ll Love Working Here

Direct User Impact

Your work will shape how thousands of people live and move around the world.

High Ownership

You’ll own meaningful parts of the product with real autonomy.

Fast-Moving Team

Short feedback loops, constant learning, and zero bureaucracy.

Performance-Based Rewards

Competitive compensation with upside for high performers.

Remote-First

Work from anywhere — outcomes matter more than hours.

🚫 This Role Is Not for You If

  • You want to work only on backend or isolated components
  • You prefer tickets over ownership
  • You’re not interested in user experience or product outcomes
  • “Good enough” is good enough
