Senior Full Stack Engineer

Who we are:

WeSki is a self-service ski trip booking platform built for the modern traveller. Our vision is simple: to make great ski experiences available to everyone. We enable customers to build and book a fully custom ski holiday in minutes, combining flights, accommodation, transfers, ski passes, equipment and lessons in one seamless flow.

Behind the scenes, our technology evaluates millions of trip combinations in real time. We dynamically connect inventory from 1,500+ suppliers, automatically optimise which components we bundle together, and present only options that really work. What used to take hours of research and coordination now takes a few clicks and finds much better results for our customers.

Every trip is fully customisable. Customers get the flexibility of building it themselves, with the security, protection, and support of a regulated holiday provider. Each trip is dynamically orchestrated in real time, with dependencies automatically managed across suppliers at scale, spanning over 300 resorts in 20+ countries across Europe, North America, Asia and Oceania. From booking to return, we manage the entire journey, so customers can relax and enjoy their holiday.

We’re about to cross $170M in annual sales. Growth is accelerating, unit economics are strong, and the business funds its own growth. High transaction volume, complex infrastructure, real impact, delivered by a small, high-performing team.

We operate in a ~$100B global ski travel market with no technology-native market leader. The industry is still dominated by traditional tour operators, with business models and infrastructure that have barely evolved in decades. This is a rare opportunity to define the future of ski travel at global scale.
