We're ASOS. We blend our flair for fashion with our love of cutting- edge technology, but more importantly were interested in how we can bring the best out of you.

We exist to give people the confidence to be whoever they want to be, and that goes for our people too. At ASOS, you're free to be your true self without judgment, and channel your creativity into a platform used by millions.

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 boost our aspiring global growth plans following the past 20 years of providing the ultimate fashion experience for 20somethings.

Last year, we shipped 73m orders to our 20m (and growing) active customers, processed 80m units of returned stock, and on our last Black Friday weekend, our systems processed over 1m orders, 42 every second at peak – pretty cool huh?!

Let our Director of Architecture, Dave Green explain how our Microservices architecture has been designed with Microsoft Azure…

How we built it: ASOS shift from local monolith to built for Cloud online retail system

ENGINEERING

Engineering at ASOS is more than just writing code. As part of our DNA, not only do we encourage everyone to “look through our customers eyes”, exploring ways to improve the general experience, but we also treat quality as a first class citizen, looking for ways to improve how we work and deliver.

Test first

Testing is not just a thing for QA engineers to sign off; it’s part of the whole development process. We champion TDD as a principle and ensure ALL our engineers are proactively contributing to the testing strategy. All platforms have designated QA engineers to support testing approaches across their teams, utilising their dedicated communities for sharing knowledge.

DevOps

Delivery isn’t for another team to complete - our engineering teams own the entire software delivery lifecycle for every work item from their backlog. By owning the CI/CD pipelines for respective services and collaborating with dependent teams, our engineers are continuously delivering solutions for our customers and optimising the process along the way.

Communities of Practice

ASOS are constantly reminded of the power of our people so we use this to our strength by establishing new communities across Tech. From QA, DevOps, Cyber Security and accessibility to Women (and Families) In Tech, Diversity & Inclusion, Engineering Managers, Coaching or Agile Ways of Working; there’s a community for everyone and plenty of opportunity to spin up more.

Learning Opportunities

We recognise everyone has personal development plans, regardless of where they’re at in their careers, so we provide many platforms and opportunities to learn and share their progress. Last Friday of the month is typically designated to personal development and learning with Tech Develops, we have a growing community of Lightning Talks, plenty of online resources including Microsoft and O’Reilly Learning and our Academy provide an endless source of training programmes.

Big Data

ASOS is a unique and forward-thinking company and understands the opportunities data and technology has on driving the business forward. Data and analytics are at the heart of everything we do, underpinning delivery, helping us make the right decisions and driving new insights within the organisation.

ORDERS PLATFORM

Our Orders services are critical to the customer experience - also known as “Golden Thread” services – to ensure orders are processed and fulfilled as soon as possible following the moment they hit the “PLACE ORDER” button.

This includes Order Processing, Payments, Delivery, Stock and Fulfilment and a whole host of dependent services. But it doesn’t stop there. When customers want to know the status of their order, or require a refund or replacement, our Order Details API provides the functionality for exposing that information in your account.

Across ASOS Tech, 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.

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, Cosmos DB and Azure KeyVault. We monitor real time usage and performance using Application insights and deploy using Terraform and Azure Devops CI/CD pipelines. For a fuller understanding of what we’ve made, check out our Solution Architect Amrish Patel’s video explanation for Microsoft:

You can also listen to one of our podcast episodes from Season 1 when Sarah Wood and Amrish talk about the event-driven architecture under the hood of our Order Processing solution, available in Apple Podcast and Spotify.

We take a test first approach to programming and use best practices like TDD, ATDD and DDD. If you have the technical skills we’re looking for and a passion for Agile delivery and fast-paced environments, come join us!
