At Xapien, we’re reinventing how organisations do that, combining speed, scale and accuracy with cutting-edge AI.\nSince 2018, we’ve grown from a deep-tech startup to a global player in AI-driven due diligence and risk intelligence. 2024 was a landmark year as we closed a $10M Series A, earned recognition in the Chartis RiskTech100® and Everest Group’s Leading 50™, and expanded our products, markets and customer base.\n2025 was even bigger: With new regulations, rising compliance pressure and growing reputation risks, organisations everywhere are demanding smarter, faster ways to work and they’re turning to us. Customers worldwide from global law firms and private banks to universities and nonprofits rely on Xapien to turn days of manual research into trusted insights, delivered in minutes.\nOur momentum so far\nCustomers in a diverse range of industries, with particular growth in wealth management, financial services and supply chain onboarding.\nDemand accelerating beyond our UK headquarters, across multiple continents with new customers in the Middle East, Asia, and Oceania.\nWhy this is an exciting time to join\nThis isn’t just another job role; it’s an opportunity to shape the future of the due diligence industry with a market-leading product trusted by global organisations. Whether you’re in marketing, communications, sales, or finance, you’ll play a critical role in driving growth, building credibility, and defining how we connect our product to a rapidly evolving market.\nWe’re scaling fast with more customers, more releases, and bigger regulatory and market challenges. Expectations are rising, due diligence now means real-time insight, delivered efficiently and with impact. You won’t just be executing campaigns, closing deals, or managing numbers, you’ll be influencing strategy, optimising processes, and helping position a brand that’s setting the new standard for trust and transparency.\nFor people who love learning, innovating, and making an impact that matters now is the moment to be a part of Xapien.\nWe turn a week of analyst work into seven minutes. Getting there took a while. Getting to \"trust it with a £10bn decision\" is the interesting part - and where you come in.\nThe work\nYou'll own parts of the Xapien pipeline end-to-end - LLM research agents, entity resolution, report generation. Prototype, evaluate, ship, measure, improve.\nBuild a system optimised for accuracy, speed and cost\n\nDesign evals that measure what matters, driving meaningful improvements\n\nDig into the failures and fix them at the root\n\nShape and ship what's next - high ownership\n\nWe use Claude Code by default and rarely write code ourselves. The craft is in careful prompting, tight loops, sharp evals, and spotting when the agent's quietly wrong.\nYou\nFluent in Claude Code, Codex, or similar agentic tooling.\n\nStrong numerical reasoning. Top-uni CS / maths / engineering / science, or equivalent in what you've built.\n\nShipped production LLM systems - RAG, prompting, agents. The kind customers pay for.\n\nYou've worked somewhere fast - startup or strong tech team - and make good calls on imperfect information.\n\nYou know software engineering: you’ve launched systems, responded to incidents, designed for failure\n\nHigh-agency. You scope problems, own solutions, and help decide what we build next.\n\nFocused on real answers for real customers. Theory's a tool, not the point.\n\nGood to work with. Small team - it matters.\n\nHere’s our promise to you:\nWe are going to work with you - to build a rewarding and fulfilling career with the opportunities, challenges and resources you need to do you your best work.\n\nWe succeed together- you will own a meaningful part of the business through our employee shares & equity programme.\n\nPrivate health insurance to keep you in tip-top condition.\n\nLife Insurance - let's hope nobody ever needs this!\n\nUnlimited holidays - yes, it really is uncapped - take the time you need, when you need it.\n\nEveryone is learning, developing and challenging themselves so we have a £1k professional development fund per year if you want to learn new skills, even new things outside of work.\n\nMost importantly of all, we will work with you, to help you realise your fullest potential, always.","description_format":"text","description_chars":4368,"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":["Equity","Health insurance","Life insurance","Professional development"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Natural Language Processing","RegTech, AML & Compliance"],"lifecycle":[{"event":"open","at":"2026-05-26T10:03:36Z"},{"event":"close","at":"2026-08-13T11:33:27Z"},{"event":"reopen","at":"2026-08-29T22:47:03Z"}],"visa":[],"liveness":{"score":26,"band":"fade","label":"Fading","p_open":1,"p_active":0.716,"p_room":0.36,"age_days":148,"expected_fill_days":96,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/xapien-senior-applied-ai-engineer","json_url":"https://alion.io/job/xapien-senior-applied-ai-engineer.json","meta":{"generated_at":"2026-10-22T19:38:33Z","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":3051,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":8279},"rest":"https://alion.io/mcp/rest/get_company?id=8279"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxapien-senior-applied-ai-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%2Fxapien-senior-applied-ai-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%2Fxapien-senior-applied-ai-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/xapien-senior-applied-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxapien-senior-applied-ai-engineer"}]}
