As a Machine Learning Engineer, you’ll develop robust, production-ready machine learning solutions, exploring, prototyping, and deploying ML approaches from initial concept through to live operation. Working at the forefront of applied AI alongside experts across multiple disciplines, you’ll help users defend against Defence and National Security threats, directly contributing to safer, more resilient systems deployed where they matter most. \nMind Foundry works on some of the most complex and urgent challenges in Defence and National Security. We specialise in supporting customers across the community to make sense at the speed of relevance from the ever-increasing volumes of data collected by sensors and systems. We often find ourselves working at the edge in complex environments where power, compute, and bandwidth are in short supply. The work is challenging, the customer needs products and applications they can trust, and the sense of achievement is therefore substantial. \nThis is an opportunity to innovate at the forefront of applied machine learning, tackle high-impact real-world problems, grow your technical skills, and shape the way AI/ML solutions are delivered to critical operational environments. \nBecause of the nature of this work: \nYou will need to hold existing or be eligible for UK Developed Vetting (DV), details of which can be found on the Gov UK website. \nBe expected to work primarily onsite at our clients’ sites in London. Please consider your commute when applying. \nKey day-to-day activities: \nDesign and build prototypes and robust, production-ready ML solutions. \nWork collaboratively with colleagues across the Mind Foundry team (Product Managers, Machine Learning Scientists, Software Engineers) to solve critical National Security challenges. \nMaintain and develop a good working knowledge of state-of-the-art ML methods, software tools and implementation methods. \nWrite maintainable production code and promote best practices for code quality in a scientific codebase. \nProvide advice and explain core ML concepts to our customers and partners. \nCore Skills & Experience: \nA degree in Computer Science, Applied Mathematics, Statistics, Physics, or a related STEM field (or equivalent practical experience). \nDemonstrated proficiency in programming languages such as Python, producing clean, reproducible, well-tested, and well-documented code suitable for long-term ownership and handover. \nHands-on experience with production infrastructure, including Docker, Linux, CI/CD, MLOps, cloud platforms, and model serving architectures. \nBe able to work with state-of-the-art ML libraries to deliver powerful results quickly. \nComfortable working in ambiguous, fast-moving environments, embedded with customers or delivery teams. \nHold existing Developed Vetting (DV) level clearance, or willing and eligible to apply and obtain UK security clearance to Developed Vetting (DV) level. \nNice to Have: \nPrior experience working with government customers, defence contractors, or in military environments. \nAbility to write technical material (documentation, published papers, internal technical notes etc). \nExperience with Natural Language Processing (NLP) and Large Language Models (LLMs). \nExperience in areas of model development, data processing and streaming (Spark, Kafka), microservices in python (Flask or FastAPI), and interactive visualisations and User Interfaces (Streamlit, Plotly, Gradio etc). \nWhile we think the above experience is important, we’re keen to hear from people that believe they have valuable skills, ideas, or perspectives that will make an impact in this role. If our team and mission resonate with you, but you do not necessarily meet all our requirements, we still encourage you to apply. \nOur Values\nWe are one team: We share goals, responsibility and success. We support one another, value what fuels people and ensure no one is left behind.\nWe work with purpose: We focus our effort where it matters most, we work hard, think smart and deliver meaningful results for our team, shareholders and customers.\nWe laugh: We protect a positive environment. We have fun, feel safe, learn, grow and achieve more together.\nWe move forward: We learn from setbacks and frustration, we support each other, solve problems together and don’t dwell on the past.\nWe act with integrity: We hold ourselves to the highest standards and are trusted, discreet and reliable. We represent our clients with the same care as we represent ourselves.\nWhat do we offer?\nWe believe in investing in our people by encouraging career and personal development that aligns with your goals and ambitions. We make sure all staff have the tools, time and support they need to shape their own professional development. We want to help you excel at what you do and support your growth within the company.\nYou’ll enjoy a competitive compensation package and great benefits such as:\nEMI options scheme\n25 days of annual leave, plus Bank Holidays\nSalary Sacrifice Pension scheme\nPrivate Healthcare (including dental and optical cover)\nGroup Life Cover\nEnhanced Parental and Sickness Leave\nUK Armed Forces Reservists Policy\nWorkplace Nursery Scheme\nVolunteering Days\nDog-friendly office\nFor more information, please visit our website www.mindfoundry.ai or email \nInterview Process: \nInitial discussion with the People team \nTestDome coding exercise \n1 hour interview with two members of the Science & Engineering Team \n90 minute technical interview, including a 10 minute presentation and live coding exercise \nIn person meet the team at our Summertown, Oxford office","description_format":"text","description_chars":5793,"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":["Annual leave","Professional development","Workplace nursery"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["National Security","Homeland Security","Machine Learning","Defense AI"],"lifecycle":[{"event":"open","at":"2026-04-02T15:52:25Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"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":"2026-10-17T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.523,"p_room":0.36,"age_days":199,"expected_fill_days":114,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/mindfoundry-machine-learning-engineer-national-security-london","json_url":"https://alion.io/job/mindfoundry-machine-learning-engineer-national-security-london.json","meta":{"generated_at":"2026-10-19T09:27:38Z","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":6563,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":24945},"rest":"https://alion.io/mcp/rest/get_company?id=24945"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmindfoundry-machine-learning-engineer-national-security-london"},{"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%2Fmindfoundry-machine-learning-engineer-national-security-london"},{"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%2Fmindfoundry-machine-learning-engineer-national-security-london"},{"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/mindfoundry-machine-learning-engineer-national-security-london\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmindfoundry-machine-learning-engineer-national-security-london"}]}
