You'll lead NFS's transition from a SQL Server-centric environment to a modern, scalable platform built on Azure Databricks and Python, while keeping Power BI delivery sharp and stakeholder-ready.\nYour domain knowledge is the differentiator. You ask better questions, catch errors faster, and build products users trust - because you understand what the metrics mean and why they matter to the business.\nWhat you'll do\nOwn complex data products - Take vague, multi-stakeholder asks (like \"we need a single view of revenue across all regions\") and turn them into governed, trusted BI products from model to report layer.\nArchitect the platform - Lead the shift to a cloud-native lakehouse on Azure Databricks with Delta Lake and Unity Catalog. Establish Python-first standards and reusable framework patterns for the team.\nRationalise KPIs - Drive \"one version of the truth\" for core metrics. Work with senior stakeholders to agree definitions and enforce them in the semantic layer.\nGovern and secure - Design access controls, RLS frameworks, and documentation standards. Spot risks early - security gaps, interpretability issues, maintainability debt - and resolve them before they compound.\nLead across functions - Partner with Regional Heads and Sales/Ops Directors to shape BI products that align with how the business actually runs. Negotiate the trade-offs that matter.\nRaise the team's bar - Define what \"good\" looks like in modelling, design, and reporting. Mentor Senior and Associate engineers. Build patterns, templates, and libraries others can reuse.\nYour toolkit\nYou'll need deep, hands-on fluency across the modern Azure data stack - and strong bridging skills for the legacy environment you're migrating from.\nPython, PySpark, Azure Databricks (Delta Lake, Unity Catalog, pipelines, notebooks, jobs), Azure Data Lake Storage Gen2, Azure Data Factory, Azure Key Vault, Power BI (complex model design, advanced DAX, RLS, performance tuning), SQL / SSMS, Git & CI/CD. Familiarity with Microsoft Fabric is a plus.\nDomain expertise\nYou'll need hands-on experience in at least one of these domains - ideally both. This isn't a nice-to-have; it's what allows you to build data products people actually trust.\nPerformance Marketing Analytics - Martech infrastructure, lead attribution, campaign optimisation. You're fluent in funnel metrics (impressions, clicks, lead volume, quality indicators) and comfortable with CPL optimisation, A/B testing, creative testing, bid management, and privacy/consent compliance.\nCall Centre Operations - Agent performance dashboards, coaching analytics, and conversion funnel analysis from lead to policy. You understand agent-level KPIs, Grade of Service, First-Call Resolution, and how lead quality, experience, product, and time of day drive conversion.\nIdeally, you can connect marketing and sales metrics end-to-end - translating lead volume and quality into sales performance expectations and identifying where friction exists in the lead-to-policy journey.\nWhat we're looking for\nSignificant experience in BI or Data Engineering roles with end-to-end accountability. A track record of designing and owning core data models, semantic layers, and critical business reports. Hands-on production experience with Azure Databricks. Advanced Power BI skills including complex model design, RLS, performance tuning, and measure authoring.\nYou think platform-first - you build solutions others can reuse, not just point fixes. You raise the bar on documentation, interpretability, and maintainability. You operate well in mid-transition environments where legacy and modern patterns coexist. You use AI tools as leverage for design, code review, and documentation, with critical judgement.\nAzure Databricks certifications are a must. A formal degree is beneficial but strong experience and evidence of impact carry equal weight.\nNFS is an equal opportunity employer. We welcome applications from all qualified candidates.","description_format":"text","description_chars":4448,"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":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Life Insurance & Annuities"],"lifecycle":[{"event":"open","at":"2026-09-17T11:13:18Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-13T08:07:55+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.293,"p_room":0.28,"age_days":100,"expected_fill_days":22,"reasons":["conf:11","win:tail","crowd:"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/neilson-financial-services-full-stack-bi-engineer","json_url":"https://alion.io/job/neilson-financial-services-full-stack-bi-engineer.json","meta":{"generated_at":"2026-11-14T04:01:44Z","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_verified","counted_by":"address","units_charged":1,"used_today":6331,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":694540},"rest":"https://alion.io/mcp/rest/get_company?id=694540"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fneilson-financial-services-full-stack-bi-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fneilson-financial-services-full-stack-bi-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fneilson-financial-services-full-stack-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/neilson-financial-services-full-stack-bi-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fneilson-financial-services-full-stack-bi-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1000518}},{"tool":"search_jobs","arguments":{"company":"neilsonfs.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1000518},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
