We are a Ukrainian-born Travel and Hospitality Technology Consulting company, partnering with online travel agencies, travel management solution providers, and startups worldwide. With expertise across Travel Tech, Data Science, UI/UX, Business Analysis, and Software Engineering, we’ve successfully delivered over 300 projects.
We are now seeking a Backend Engineer to join one of our client projects focused on building scalable, intelligent systems that redefine customer engagement. You’ll play a key role in designing cloud-native services, integrating AI-driven APIs, and ensuring that the platform is reliable, high-performing, and ready for large-scale usage.
The team is developing a next-generation platform for customer engagement powered by generative AI. The solution enables travel and lifestyle companies to deploy intelligent, always-available digital agents that provide personalized support and seamless brand interactions at scale. By combining advanced GenAI models with a proprietary learning engine and deep integration into business systems, the platform helps brands create efficient, consistent, and meaningful conversations with their customers.
