Job description

About Heidi

Heidi was born to make it easy for more and more people to discover the power of the mountains. We burst onto the ski holiday market in 2018 (formally known as Ski Zoom) and have seen exponential growth.

The company came from a desire to fix the lack of flexibility in the winter ski market. We help skiers and mountain lovers discover resorts that are hidden gems alongside the classics, and our clever tech is helping them to do it in a way that suits them best. We’re a youthful, challenger brand, with an awesome culture, and we’re shaking up a very traditional ski/mountain holiday industry.

Looking to the future, we have huge ambitions for growth. In 2024 we grew by 64% and expect to grow even more in 2025. Having come 63rd in the Times top 100 fastest growing UK companies, and shortly after securing £5.6 million investment, we are in a prime position to achieve our goals. But key to that is also growing the Heidi team with even more brilliant people than we have now. So we are looking for someone who will be fundamental to the success of our vision and is excited to help us drive that forward.

• Delivering work using agile methodologies.
• Contributing to cross cutting concerns that improve our engineering function.
• Being actively involved in the planning and technical architecture of our company roadmap.
• Helping the team meet its goals by collaborating with and helping other team members.

What you will bring

• Experience with cloud native ASP.NET Core APIs. (5 years c# language / ASPNET core)
• You’re experienced with relational database design and performance optimization. (MySQL, SQL Server)
• You have experience with front-end Javascript frameworks and website performance. (javascript, react etc.)
• Docker experience for developer, testing and ideally production environments [Bonus: if you have experience hosting your own application in real production environments with production traffic (not handing off to an ops team)]
• Leadership experience within a team.
• Delivery focused but aware of the bigger picture and can design systems to adapt and change over time
