At ASOS, you're free to be your true self without judgement, and channel your creativity into a platform used by millions.\nEveryone needs some help showing up as their best self. We're Disability Confident Committed - let our Talent team know if you need any reasonable adjustments throughout the recruitment process\n We’re looking for a Senior BI Engineer to work along with our BI team in FinTech and Fashion Tech. Reporting to the Staff Engineering Lead, you will take the strategy they set and turn it into delivery, leading the team day to day and being the senior, most experienced pair of hands on the data side.\nThe team owns reporting and BI across all of FinTech and Fashion Tech. That covers the reports our business runs on, the reconciliations that keep our data feeds honest, and ownership of the data warehouse and the data sync between our ERP and the wider estate.\nOur stack is Python, PySpark, Delta Lake and Databricks, with T-SQL, Kimball dimensional modelling and Power BI on top, working closely with Microsoft Dynamics 365 Finance and Operations data structures. We are currently reviewing whether to move from Databricks to Microsoft Fabric, so you should be comfortable working through a platform decision and the migration that may follow.\nKey Responsibilities\nBeing Mentor to the BI Team\nSupport the BI team day to day, turning the strategy set by the Staff Engineering Lead into a plan the team can deliver against.\n\nSupport and mentor the other BI Engineers on both reports and the data side, through design reviews, pairing and code review.\n\nBe the senior technical voice in the team. Set the standards for how we model, build and test, and raise the bar on quality.\n\nPrioritise and balance the team’s work across reporting requests, reconciliations and platform work, and pick up the hardest builds yourself.\n\nOwning the Data Warehouse and Data Sync\nOwn our data warehouse, including the dimensional model, the pipelines that load it and the standards that keep it consistent as it grows.\n\nOwn the data sync between our ERP and the warehouse, making sure data lands completely, on time and in a shape the business can use.\n\nBuild and maintain the reconciliations that prove our feeds are complete and accurate, and investigate and fix them when they break.\n\nReporting and BI Delivery\nDeliver reporting our stakeholders trust, from the models underneath through to well built, performant Power BI reports.\n\nDesign and build data pipelines in Python, PySpark and Delta Lake, and write the T-SQL behind our models and reconciliations.\n\nKeep an eye on cost, performance and reliability across the platform, and keep improving what is already live.\n\nWorking with Stakeholders\nWork with stakeholders across Finance, Tech and Fashion, including our Commercial, Buying and Product colleagues, to understand what they need from their data.\n\nTurn reporting requests into well shaped requirements, and challenge constructively when an existing report or a different cut of the data would do the job.\n\nKeep stakeholders updated on progress, priorities and any risks to the data they depend on, so there are no surprises.\n\nWorking Across Tech\nWork closely with the solution, engineering and support teams across FinTech and Fashion Tech, so changes upstream in the ERP don’t break reporting downstream.\n\nFollow the wider ASOS delivery process, including governance, change control and release cadence, and run the team’s work through Azure DevOps.\n\nWork with Architecture, Security and Risk so what we build meets ASOS standards, protects sensitive financial data and stands up to audit.\n\nWhy This Role Matters\nAlmost every decision our Finance and commercial teams make rests on numbers this team produces, from month end close and supplier payments through to trading, stock and range performance. If the warehouse is wrong or a feed silently drops data, people make the wrong call.\nThis role is where that quality is set. We need someone senior enough to own the warehouse and the ERP data sync end to end, lead a team through a possible platform move, and still be close enough to the detail to build the hard things themselves.\nData and BI Experience\nStrong hands-on experience with Python, SQL, PySpark and Delta Lake for building scalable data pipelines.\n\nExperience across the Azure data stack, including Azure Data Factory (ADF), Azure Functions, Logic Apps and Azure Storage.\n\nStrong experience with Databricks and Microsoft Fabric, including Lakehouse and modern data engineering solutions.\n\nStrong SQL/T-SQL skills and experience with Kimball dimensional modelling and data warehouse design.\n\nExperience integrating ERP data, ideally Microsoft Dynamics 365 Finance & Operations or other major ERP platforms.\n\nWorking knowledge of Power BI, DAX and data modelling, with a focus on delivering effective business reporting.\n\nLeadership\nExperience leading or mentoring other engineers, setting technical standards and lifting the quality of what a team produces.\n\nComfortable taking a strategy someone else has set and turning it into a plan your team can deliver.\n\nAble to prioritise across competing requests and make a clear call on what gets done and what waits.\n\nStakeholder Management and Rigour\nConfident with stakeholders across Finance, Tech and the commercial teams, able to explain data simply and push back when a request doesn’t stack up.\n\nA genuine eye for data quality, with the patience to chase a reconciliation break until you find the root cause.\n\nOrganised and calm under pressure, particularly around month end and peak trading.\n\nWe’d Also Love to See\nExperience of a lakehouse or warehouse migration, or of working through a platform decision such as Databricks to Microsoft Fabric.\n\nKnowledge of finance or supply chain processes such as procure to pay, order to cash, month end close or stock and warehouse operations.\n\nExperience in retail, ecommerce or fashion, particularly reporting for buying, merchandising or trading.\n\nExperience with CI/CD for data, testing frameworks, data observability or governance and cataloguing tools.\n\nWhy You’ll Love This Role\nYou will own the data warehouse and the ERP data sync for two of the most important areas of ASOS.\n\nIt is a rare mix. You get to lead and mentor a team, set the technical standards, and still build the hard things yourself.\n\nA modern stack with a genuine platform decision ahead, and a real say in where we take it.\n\nBroad exposure across Finance, Commercial, Buying and Product, with work that visibly shapes how ASOS makes decisions.\n\n BeneFITS’\nEmployee discount (hello ASOS discount!) \nEmployee sample sales \n25 days paid annual leave + an extra celebration day for a special moment \nDiscretionary bonus scheme \nPrivate medical care scheme \nFlexible benefits allowance - which you can choose to take as extra cash, or use towards other benefits \nOpportunity for personalised learning and in-the-moment experiences that enable you to thrive and excel in your role","description_format":"text","description_chars":7161,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Annual leave"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Commerce","Consumer Goods"],"lifecycle":[{"event":"open","at":"2026-10-05T18:15:49Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker, Senior or Specialist Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker; Global Business Mobility: Senior or Specialist Worker","cap_exempt":false,"checked_at":"2026-10-08T06:20:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":88,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.876,"p_room":1,"age_days":2,"expected_fill_days":14,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-08T05:49:30Z"},"pay":null,"html_url":"https://alion.io/job/asos-senior-bi-engineer","json_url":"https://alion.io/job/asos-senior-bi-engineer.json","meta":{"generated_at":"2026-10-09T03:22:07Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1957,"day_limit":5000,"remaining_today":3043,"minute_limit":60,"resets_at":"2026-10-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":39790},"rest":"https://alion.io/mcp/rest/get_company?id=39790"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fasos-senior-bi-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fasos-senior-bi-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fasos-senior-bi-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/asos-senior-bi-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fasos-senior-bi-engineer"}]}
