Software Engineer - Orders

ASOS Technology is going through an exciting period of transition and major investment. – this includes a number of strategic programmes to deliver the amazing technology and business solutions to support our ambitious global growth plans. At the heart of these plans is the rebuilding of our digital platforms and channels to provide the best shopping experience for our customers. Our plan is designed to enable us to really put our mobile experience first, enable personalisation and support a data driven organisation. We are also making significant investments in all our Buying, Merchandising, Finance and People systems with the latest toolsets and applications to accelerate the next phase of our global growth. We are also improving our ways of working within Technology to enable autonomous platform development and improve our engineering and agile practices.

In the Orders platform, we pride ourselves on creating innovative and friction-free tech solutions. These enable ASOS to provide our global customers a first-class order management proposition with the ability to place, track and return an order anytime, anywhere so we strive for a zero-downtime platform. Last year, we shipped 73million orders to our 20m (and growing) active customers, processed 80m units of returned stock, and on our last Black Friday sale, our systems processed over 1m orders – pretty cool huh?!

To achieve this scale (and future growth), we are currently investing in a major re-platforming programme on our .NET architecture. We build our solutions in the Azure cloud primarily using Azure Functions running images built using Docker and .NET Core. We back this up using resources including Azure Service Bus, CosmosDb and Azure KeyVault. We monitor real time usage and performance using Application insights and deploy using Terraform and Azure Devops CI/CD pipelines. We take a test first approach to programming and use best practices like TDD, ATDD and DDD.
