Join Compare the Market and help to make financial decision making a breeze for millions.\nAt Compare the Market, we’re a purpose-driven business powered by tech and AI. We’re building high-performing, results-driven teams with the skills, mindset, and ambition to deliver outcomes at pace. Every role here plays a part in driving our mission forward, and we create an environment where you can bring your authentic self, grow a truly characterful career, and see the direct impact of your work on the lives of our customers.\nWe’ve carved a meerkat-shaped niche and we’re looking for ambitious, curious thinkers who thrive in a fast-moving, high-impact environment. If you love accountability, embrace challenge, and want to make a real difference, you’ll fit right in.\nWe’d love you to be part of our journey.\nCompare the Market is building AI systems that connect directly to how millions of people in the UK find and buy financial products - and as a Machine Learning Engineer, you will play an important role in making those systems production-ready. That means contributing to the engineering that takes ML models and AI capabilities from experimentation into reliable, scalable production use: the pipelines, the deployment tooling, the monitoring, and the shared components that make the whole thing work.\nThis is a hands-on role where you will grow your technical skills across a fast-moving and expanding set of AI capabilities and systems. You will work closely with data scientists, engineers, and product teams - delivering well-scoped ML and AI features, contributing to engineering standards, and building your understanding of what good looks like in a modern ML engineering function.\nSome of the great things you'll be doing:\nML Engineering and AI Systems\nDeliver well-scoped ML and AI system components end-to-end, from design through to testing, deployment, and production support \nContribute hands-on code to model packaging, deployment, and lifecycle automation \nBuild and improve systems that monitor model performance, drift, reliability, and operational health\nSupport both batch and real-time ML workloads depending on use case requirements \nWork on emerging AI and LLM-powered capabilities, helping integrate modern AI techniques into production systems where they can deliver real user value \nPlatform and Standards\nContribute to the evolution of our internal ML and AI platform to support experimentation, governance, and collaboration \nApply and help promote best practices for ML and AI system design, including reproducibility, testing, CI/CD, model and agent observability and evaluation \nContribute to shared tools and libraries that accelerate safe, efficient, and scalable ML development \nCollaboration\nWork closely with data scientists to help productionise experimental models and turn prototypes into robust services\nContribute to code reviews, providing and receiving constructive feedback \nParticipate in architecture and design discussions, raising considerations around scalability, reliability, and system interactions \nCulture and Innovation\nContribute to a culture of engineering excellence, collaboration, and continuous learning \nStay curious about emerging tools and approaches in MLOps and applied AI, and bring ideas for improvement to the team\nSupport responsible AI practices, contributing to explainability, auditability, and fairness in ML systems \nWhat we'd like to see from you:\nThe Essentials\nSome experience delivering ML or AI components in a production or near-production environment \nSolid software engineering skills in Python, with an understanding of how to write maintainable, testable code \nFamiliarity with ML tooling and platforms such as Databricks, MLflow, Airflow, or equivalent\nFamiliarity with CI/CD pipelines and how they apply to ML systems \nAn understanding of ML lifecycle challenges - versioning, testing, monitoring, governance \nGood collaboration and communication skills, with an ability to work effectively across data science, engineering, and product teams \nNice to Have\nExposure to LLM-based systems - for example prompt engineering, RAG, or orchestration frameworks such as LangGraph or LangChain\nFamiliarity with multi-step AI patterns - systems where models plan, retrieve information, and take sequences of actions \nActive personal use of AI-assisted or agentic coding tools, and an interest in how similar patterns could be applied to automate and accelerate ML engineering workflows - candidates who are exploring this space, even at an early stage, are encouraged to talk about it \nExperience or interest in financial services, insurance, or another regulated sector \nInterest in responsible AI and ML model governance \nWhy Compare the Market?\nWe’re a business built for pace and performance. Here, you’ll be encouraged to think differently, act boldly, and deliver brilliantly in a culture that values results and rewards progress.\nWe believe diverse teams make better decisions, and we’re committed to creating an inclusive workplace where everyone feels empowered to grow, contribute, and thrive.\nIf you’re ready to stretch yourself, raise the bar, and grow with a team that’s serious about performance, innovation, and purpose, we’d love to hear from you.","description_format":"text","description_chars":5375,"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":["Continuous learning"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-06T22:14:02Z"}],"visa":[],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.84,"p_room":0.945,"age_days":8,"expected_fill_days":25,"reasons":["conf:2","win:mid"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/compare-the-market-machine-learning-engineer","json_url":"https://alion.io/job/compare-the-market-machine-learning-engineer.json","meta":{"generated_at":"2026-11-07T20:29:13Z","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":32531,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":1762840},"rest":"https://alion.io/mcp/rest/get_company?id=1762840"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcompare-the-market-machine-learning-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%2Fcompare-the-market-machine-learning-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%2Fcompare-the-market-machine-learning-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/compare-the-market-machine-learning-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcompare-the-market-machine-learning-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3893230}},{"tool":"search_jobs","arguments":{"company":"comparethemarket.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3893230},"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.
