TENEX.AI is hiring a Lead Full-Stack Engineer

About the Role

Shape the foundation of a global rental platform as the Lead Full-Stack Engineer. You’ll be responsible for the full technical scope of The Flex platform, guiding its architecture and execution across web interfaces, backend services, APIs, and cloud infrastructure. This role blends deep technical leadership with hands-on development, focusing on long-term scalability and operational precision.

What You’ll Do

  • Lead the design and evolution of system architecture for core functions including bookings, payments, pricing, and guest interactions
  • Build and refine full-stack features, from React frontends to FastAPI services and serverless AWS components
  • Design robust, API-first systems that integrate with platforms like Airbnb, Stripe, Hostaway, and Twilio
  • Develop event-driven workflows to automate operations and reduce manual overhead
  • Ensure high availability, security, and performance across global deployments
  • Establish coding standards, lead code reviews, and mentor through technical example
  • Drive real-time capabilities such as booking synchronization, AI-driven alerts, and live dashboards

What We’re Looking For

  • Proven experience leading technical architecture in production environments
  • Strong command of FastAPI, React, and AWS at scale
  • Track record of building reliable, API-centric systems used in real-world applications
  • Commitment to clean, maintainable code and long-term system resilience
  • Self-starter mindset with a focus on execution and technical ownership

Why This Matters

You’ll help define not just features, but the core engineering principles of the platform. Working alongside a lean, high-signal team, you’ll operate with full autonomy and direct influence over the product’s trajectory. Compensation is competitive, with upside tied to impact. We’re remote-first—work from anywhere—and prioritize outcomes over presence.
