Full Stack Engineer

At iFLY, our mission is to deliver the dream of flight to everyone! A global company with over 100 vertical wind tunnels in 19 countries (corporate and franchise), iFLY offers an exciting opportunity to join a successful and innovative organization that supports your professional growth.

We are looking for an experienced Full Stack Engineer who will also serve as a Development Manager to lead the design, development, and delivery of modern web applications and Point-of-Sale (POS) systems. The ideal candidate is a hands-on engineer with strong full-stack expertise, deep knowledge of POS architecture and integrations, proven experience leveraging AI-assisted development tools and AI-driven features within products, and has demonstrated exposure to advertisement platform integrations, conversion rate optimization (CRO), and end-to-end performance tuning.
