Des trains à grande vitesse, métros, monorails et tramways aux systèmes intégrés, services, infrastructures, et solutions de signalisation et de mobilité numérique, nous offrons à la diversité de nos clients le portefeuille le plus vaste du secteur. Chaque jour, plus de 80 000 collaborateurs dans le monde qui ouvrent la voie à des solutions de mobilité plus vertes et plus intelligentes pour relier les villes, réduire l’empreinte carbone et remplacer la voiture.\nSujet du stage :\nÉtude et comparaison de méthodes de Machine Learning pour données de simulation et d'essais.\nLa création de modèles à partir de données issues de simulations numériques ou de mesures expérimentales présente un grand intérêt pour la compréhension des phénomènes physiques et la prédiction de nouveaux cas de fonctionnement.\nL'objectif du stage est d'évaluer différentes méthodes de Machine Learning disponibles dans les bibliothèques Python PyTorch et scikit-learn, afin d’identifier leurs domaines d’application, leurs besoins en données et leurs performances sur différentes problématiques.\nLe stage consistera également à développer des fonctions génériques permettant de préparer et mettre en forme les données afin de faciliter l'utilisation de ces méthodes.\nNous proposons un stage de niveau Bac+5 pour un profil en mathématiques appliquées, informatique ou data science.\nDéveloppement du sujet :\nLes activités de cette étude seront les suivantes :\nAnalyse des méthodes disponibles dans PyTorch et scikit-learn ;\nMise en place de fonctions génériques de préparation des données ;\nMise en œuvre et évaluation des différentes méthodes ;\nComparaison des performances et identification des cas d'utilisation adaptés ;\nRédaction d'un rapport de synthèse.\nExport des modèles vers un format standard (ONNX) ;\nDéveloppement d'un wrapper C/C++ permettant la réutilisation des modèles exportés dans des applications externes ;\nÉvaluation sur différents cas d'application (thermique, batteries, modèles récursifs, PINN).\nIl n’y a pas que les passionnés de trains qui s’épanouissent chez nous. Nul doute que vous ressentirez beaucoup de fierté lorsque vous monterez dans l’un de nos trains avec votre famille ou vos amis. Si vous aimez le challenge, nous serions ravis d’échanger avec vous !\nRemarque importante\nEn tant qu’employeur présent dans plus de 63 pays, nous souscrivons au principe d’égalité d’accès à l’emploi et valorisons la diversité. Nous nous sommes engagés à créer un environnement de travail inclusif pour tous.\nJob Type:Stage/Apprenti","description_format":"text","description_chars":2677,"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":[{"language":"French","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Rail Transport"],"lifecycle":[{"event":"open","at":"2026-10-29T12:44:04Z"}],"visa":[],"liveness":{"score":47,"band":"ok","label":"Likely open","p_open":1,"p_active":0.86,"p_room":0.55,"age_days":23,"expected_fill_days":20,"reasons":["conf:5","velocity","win:tail","comp:junior,brand"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/alstom-stage-ingenieur-e-techniques-doptimisation-machine-learning","json_url":"https://alion.io/job/alstom-stage-ingenieur-e-techniques-doptimisation-machine-learning.json","meta":{"generated_at":"2026-11-06T19:36:02Z","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":3103,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":445391},"rest":"https://alion.io/mcp/rest/get_company?id=445391"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Falstom-stage-ingenieur-e-techniques-doptimisation-machine-learning"},{"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%2Falstom-stage-ingenieur-e-techniques-doptimisation-machine-learning"},{"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%2Falstom-stage-ingenieur-e-techniques-doptimisation-machine-learning"},{"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/alstom-stage-ingenieur-e-techniques-doptimisation-machine-learning\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falstom-stage-ingenieur-e-techniques-doptimisation-machine-learning"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3457415}},{"tool":"search_jobs","arguments":{"company":"alstom.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3457415},"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.
