Job description

At Mountain Warehouse we understand that technology is core to our success as a business and so we invest heavily in our in-house team. The development department is divided into product-based teams, all using variants on Kanban for project prioritisation and a focus on continuous delivery, mostly with usage of microservices.

We are a collaborative team with a strong culture of code review, occasional usage of pair programming and lots of unit tests. We’re keen to write code following best practice and to continuously find ways that we can be even better. The work is a mixture of green-field and legacy projects (much like any other mature organisation) mostly using C#, SQL Server, Next.js, React & TypeScript, with a combination of monolithic and microservices architectures.

We are looking for technically strong and organised senior developers to join our development teams, with positions available across the Web Development team, the team responsible for systems related to Customer Experience and Customer Service as well as our Buyers and Merchandising development team.

The applications are a mixture of internal services and public-facing applications, based on a range of tech stacks and across cloud, datacentre, and modern edge/serverless environments.
