It builds the science and AI behind our platform, from job analysis and assessments to AI interviews and predicting performance. Led by our Head of Science, Aiden Loe, and working closely with our COO, Paul-Louis Caylar, the team brings together business psychologists, psychometricians and AI scientists. Together, they make sure every hiring decision on our platform is accurate, consistent and fair.\nAs Maki grows, the Science and AI team’s job is to show, with evidence, that our approach leads to better hiring decisions.\nAbout the Role\nThe AI Applied Scientist turns our science into results for clients. Most of your time goes on client projects: adapting our AI scoring to each client’s roles, analysing their data, and showing them what it means. The rest goes on improving the scoring systems that every client relies on.\n1. Client projects\nAdapt AI scoring for structured interviews, job-specific skills and multilingual proficiency to each client’s roles and needs.\n\nAnalyse client assessment and performance data to show how scores relate to job performance and retention.\n\nSet and review cut-offs and thresholds with clients, backed by evidence.\n\nPresent findings and recommendations directly to clients, in a way non-technical audiences can act on.\n\nWork closely with implementation and customer success teams from setup to go-live.\n\n2. Testing scoring quality\nCompare AI scores with expert ratings to check accuracy and reliability before anything goes live.\n\nTest robustness to prompt variation, input noise and adversarial behaviour such as prompt injection.\n\n3. Fairness in practice\nRun bias checks across demographic groups for each client project.\n\nApply mitigation techniques such as reweighting and calibration without losing model performance.\n\nSupport fairness reports and compliance documentation for clients.\n\n4. Improving our scoring systems\nHelp choose the right models and prompts for production, balancing accuracy, speed and cost.\n\nSupport the move onto self-hosted open-weight models, including fine-tuning on expert-rated data.\n\nWork with engineering to roll out scoring changes safely.\n\nAs one of Maki People’s early employees, you’ll help shape the team’s future.\nOur Ideal Candidate\nRequired\nMSc or PhD in data science, machine learning, psychology or a related field, or equivalent industry experience.\n\nHands-on experience with LLM-based scoring or evaluation.\n\nStrong Python or R skills, with solid statistical analysis.\n\nExperience presenting data-driven findings to clients or senior business stakeholders.\n\nAble to manage several projects at once and keep to deadlines.\n\nPreferred\nExperience in consulting, people analytics or assessment.\n\nWorking knowledge of psychometric concepts such as reliability, validity and IRT.\n\nExperience testing AI systems for fairness and bias.\n\nExperience fine-tuning language models, for example with LoRA.\n\nWorking knowledge of ethical AI and compliance, such as the EU AI Act.\n\nApplication Process\nStage 1 - Screening assessment (25 min)\n\nStage 2 - Power skill assessment with our AI agent (15 min)\n\nStage 3 - Hiring manager interview (45 min)\n\nStage 4 - Executive interview (45 min)\n\nStage 5 - Deep-dive technical interview (60 min)\n\nStage 6 - Interview with Co-founder (30 min)","description_format":"text","description_chars":3343,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"},{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["HR & Recruiting AI","Recruiting Software & ATS"],"lifecycle":[{"event":"open","at":"2026-11-13T19:50:23Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":38,"reasons":["conf:4","win:early"],"computed_at":"2026-11-14T06:15:48Z"},"pay":null,"html_url":"https://alion.io/job/maki-ai-applied-scientist","json_url":"https://alion.io/job/maki-ai-applied-scientist.json","meta":{"generated_at":"2026-11-14T06:15:48Z","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":10551,"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":679502},"rest":"https://alion.io/mcp/rest/get_company?id=679502"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmaki-ai-applied-scientist"},{"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%2Fmaki-ai-applied-scientist"},{"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%2Fmaki-ai-applied-scientist"},{"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/maki-ai-applied-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmaki-ai-applied-scientist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4278763}},{"tool":"search_jobs","arguments":{"company":"makipeople.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4278763},"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.
