Your Role

Senior Data Engineer – Indirect Tax & Customs

London | Hybrid – 3 days per week in office | Permanent

The Opportunity

We're looking for a Senior Data Engineer to help us rethink how data and technology are used across Indirect Tax & Customs.

In a high-volume global e-commerce business, tax outcomes are created across millions of transactions and multiple systems spanning customer orders, payments, fulfilment, logistics, customs, returns and finance.

We want to connect that data.

You'll work directly with Indirect Tax & Customs specialists and with Data, Technology, Finance and Supply Chain teams to build scalable data products, automated controls and analytics that solve real business problems.

This isn't a traditional tax role. You don't need to be a VAT or customs expert.

We're looking for a strong data engineer who is curious about complex business processes and wants to use technology to fundamentally change how they work.

What You'll Do

You'll help us build a trusted data foundation connecting the complete transaction lifecycle:

Order → Payment → Fulfilment → Shipment → Customs → Tax → Return → Accounting → Compliance

You'll:

  • Design and build scalable data pipelines across complex transactional systems
  • Develop reusable data models supporting tax, customs, finance and supply-chain outcomes
  • Automate reconciliations currently dependent on manual data manipulation
  • Build controls that analyse complete transaction populations and identify exceptions
  • Connect ERP, e-commerce, logistics, customs and tax datasets
  • Develop analytics and dashboards that identify risk and financial opportunities
  • Improve data quality, lineage and auditability
  • Explore opportunities to use automation, machine learning and AI to solve tax and customs challenges.

You'll have the opportunity to work on problems such as:

Can every customs declaration be matched back to the correct shipment and transaction?

Are all transactions reaching the correct VAT reporting process?

Can we automatically identify import VAT that hasn't been recovered?

Can we detect unusual tax outcomes before they become compliance issues?

Can we use data to identify customs duty savings or recovery opportunities?

What We're Looking For

You'll bring strong technical data engineering experience, including:

  • Expert T-SQL skills including performance tuning – Microsoft SQL Server
  • ETL/ELT pipelines – Databricks, Azure Data Factory, Fabric
  • Data-warehousing, dimensional modelling, and dimensional data mart design
  • Building analytics and dashboards in Power BI
  • APIs and integrations
  • Large-scale transactional datasets
  • Alteryx or similar analytics automation tools, including building governed, repeatable workflows for data ingestion, transformation, validation, reconciliation and exception reporting
  • Data quality and automated testing
  • Modern development and version-control practices – GitHub and Azure DevOps.
  • Experience with Dynamics 365 for Finance & Operations (D365F&O) is highly desirable

Do I Need Tax Experience?

No.

Experience with VAT, customs or tax technology would be useful, but it isn't essential.

You'll work alongside experienced Indirect Tax & Customs specialists.

We're more interested in your ability to understand complex problems, connect and interrogate data across multiple systems and build scalable solutions.

What Makes This Role Different?

You won't simply receive tickets asking you to build reports.

You'll work directly with the people who understand the business problems.

You'll help decide what should be built, how it should work and how success should be measured.

The ambition is to move from:

Extract → Excel → Reconcile → Fix

to:

Connected Data → Automated Controls → Exceptions → Insight → Prevention.

You'll also help create the data foundation for the next generation of tax technology, including automation, advanced analytics and AI.

What Success Looks Like

During your first year, you'll help us:

  • Build a trusted Indirect Tax & Customs data foundation
  • Automate key reconciliations
  • Introduce continuous, exception-based controls
  • Reduce manual spreadsheet-driven processes
  • Identify tax and customs leakage opportunities
  • Improve visibility of tax risk
  • Develop new automation and AI use cases.

If you enjoy solving complex data problems and want to see your engineering work translate directly into measurable business outcomes, we'd love to hear from you.

Operations @ ASOS

Every single day I feel both supported and inspired! The constant flow of creativity within ASOS is contagious. It's cool to be encouraged to think outside the box.
I was initially drawn to ASOS as it is a reputable company with a culture that is unmatched. After joining ASOS I soon realised that just like the name, it was most definitely ‘As Seen On Screen’ – what you see is truly what you get. There are endless opportunities within the company with values embodying a culture of bringing your best self to work. I never feel as though I need to change to fit the status quo of the ‘corporate lifestyle’ but actually, I fit in more when I’m authentically being myself.
At ASOS I can bring my authentic self to work, you’re empowered to think different, innovate and do the things you love. ASOS is a fast paced, changing environment with fun at the heart of everything we do.

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.
