.net Developer (Channels & Marketplace)


The development team at Mountain Warehouse is split into small teams, each looking after a different set of applications and using a Kanban approach to prioritisation.

We are a collaborative team with a strong culture of code review, occasional usage of pair programming, 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 work (much like any other mature organisation) mostly using C#, TypeScript, SQL Server & React – however, the microservices approach allows us to alter the technology as appropriate.

We are looking for a developer to join our Channels & Marketplace team – responsible for the accurate and timely flow of data that power all our sales on third party sites (Amazon, ebay, Next, etc.) and allow third parties to sell on our website.
