As a Senior AI Engineer, you will be part of the AI Platform team, helping to build and scale the shared foundations that enable AI capabilities across ASOS. The primary focus of this role will be contributing to the Agentic AI Platform initiative, alongside other core AI platform capabilities as the platform evolves.
This role is focused on the platform layer, rather than individual business use cases. You will design and implement shared standards, templates and reference implementations for agentic AI on Azure, enabling application teams to safely design, deploy and operate AI agents at enterprise scale. Working closely with Product teams, Cloud Infrastructure, Security and partners, you will help ensure AI capabilities are secure, observable, reusable and governed by default. You will also contribute to the production foundations needed to operate AI capabilities reliably, including LLMOps, model access patterns, prompt and agent lifecycle practices, observability and secure enterprise integration.
What you’ll be doing
Designing and building AI platform capabilities on Azure, with a strong focus on agentic AI patterns such as agent runtimes, orchestration and tool integration
Contributing to the Agentic AI Platform initiative, helping define how agents are built, integrated and operated across the organisation
Designing and maintaining standardised templates and reference implementations for LLM and Generative AI workflows, enabling teams to adopt consistent patterns for prompt design, tool calling, multi‑step agent flows, retries and failure handling
Implementing secure, governed access patterns for LLMs and enterprise tools using APIM, platform gateways, Entra ID, RBAC and managed identities
Contributing to LLMOps and model runtime patterns, including standard approaches for model access, routing, caching, token optimisation and cost‑aware usage controls
Supporting lifecycle and evaluation practices for agent configurations, prompts and AI workflows, including testing, controlled change and release readiness
Designing secure tool-access patterns for agents, including MCP/tool abstraction, credential management and enterprise API integration.
Contributing to AgentOps and GenAIOps capabilities, including telemetry, run history, task outcomes, error analysis and feedback loops
Contributing to reliability patterns for production AI systems, including latency monitoring, alerting, scaling considerations and operational readiness.
Applying CI/CD and software engineering best practices to AI platform and agentic components
Embedding observability by default, ensuring AI systems are measurable, debuggable and auditable through logs, metrics and traces
Partnering with Cloud Infrastructure and Security teams to design secure, scalable and cost‑effective Azure environments

Tech @ ASOS
I love working at ASOS in my team because of the great atmosphere. From day one I already felt like being part of the team, everyone is so friendly, approachable and willing to help. It’s the place where you feel trusted and are given the opportunities & time to explore your full potential. As someone who just relocated to London, I also appreciate the international and cultural diverse environment – it’s ok to be whoever you want to be!
As a software engineer with a love for fashion, I feel extremely lucky to be part of a fashion company that priorities technology, innovation and customer experience to the same degree as their clothing.
As someone who left ASOS after 7 years but came back, it speaks volumes how much I love working at ASOS. The obvious reason is the people, not just in Tech but beyond. There's an unspoken respect and authenticity between everyone who works here

We are Customer First
We couldn’t be ASOS without our customers.
Across every behaviour, value, and all that we do, we see everything through our customers’ eyes. That means never taking anything for granted and always zeroing in on every single detail. So we can always bring our best as a team, and our customers can have an amazing experience, every time.
We are Authentic
We work together to be honest, transparent, and our full authentic selves.
This is our ASOS. Our culture, built on collaboration and togetherness, and supported by what’s real and honest. We know that we win bigger when we win as a diverse team. That means celebrating our differences and using them to help us stand out from the crowd, without losing our authenticity and individuality.
We are Brave
We challenge each other to aim high and reach our potential.
Doing nothing gets us nowhere. We may be proud of everything we’ve done so far, but there’s still so much more to explore. We believe we can always be wiser, faster, stronger, bigger, braver, kinder…so asking ‘why’ isn’t just a question, it’s a necessity. We use our voice to drive us forward, speaking up on the things our people and customers care about and using our curiosity to create possibility.
We are Creative
We know innovation leads to inspiration – it’s what makes us stronger
Change is in our DNA. By acting fast and staying one step ahead of the curve, we can be a leader, not a follower. But for our products and platform to be innovative, they have to be fuelled by creative passion and a deep understanding of our customers and our people.
We always Deliver
We couldn’t be excellent without evidence – so whatever we’re doing, we have proof of why we’re doing it.
It takes facts and data to tell our stories and help us make our decisions in the most effective way possible. This means we can do what we say and own what we do, no matter how long it takes us to do it. We aren’t about nonsense ifs, buts and maybes, we’re about creating an ASOS that’s built for future success on delivered success.
Our Benefits
Employee Discount
The most asked-about benefit! As an ASOSer, you’ll receive an exclusive employee discount. You can also nominate a family member or friend to share your discount with.
Pension
Retirement might not be on your mind right now, but it’s important to prep for it. We offer matched contributions up to 5% to help you save.
Private Medical Care scheme
If you join our Private Medical Care scheme, you’ll get fast and effective access to medical cover.
Bonus
What we achieve is always a team effort. That’s why we offer a discretionary bonus scheme which rewards you based on our group financial and strategic performance.
Celebratory Day!
Get an extra day off in addition to the 25 days of annual leave you get! Spend it celebrating the big days in life, whether it’s birthdays, cultural holidays, weddings and anything else.
Shuttlebus Service (if you're based in our Leavesden office)
It’s more of a work perk, but we offer a free shuttlebus between Watford station and our office in Leavesden.
Sample Sales
We’ve always got fun things happening in our offices, but the one ASOSers get most excited about is our sample sales. Plus, all proceeds from the sample sale get donated to the ASOS Foundation, which helps our charity partners abroad.
Career Development
You’ll have the opportunity for personalised learning and in-the-moment experiences to create a dynamic and agile learning environment that empowers you to thrive and excel in your role.
Summer Hours
We finish at 3pm on Fridays in June, July and August!! This perk doesn’t mean a dip in your salary – it just gives you extra freedom to enjoy those summer weekends however you want.
Location
Our HQ in London
Our HQ in Camden was once a cigarette factory – now, the iconic Art Deco building has been completely renovated with spacious office areas, ASOS Studios (where we shoot all our products), beauty rooms and a free gym. There’s also a subsidised canteen and café.
