L'objectif est de développer un modèle dynamique en Python pour simuler l'ensemble de la chaîne de valeur du CO2, depuis le captage sur le site cimentier jusqu'à sa valorisation. À partir de données Excel internes et d'hypothèses projet définies, vous construirez un outil interactif permettant d'effectuer des tests de résistance (stress-testing) sur différents scénarios techniques et économiques.\nVos missions :\nAu sein de ce projet, vos principales responsabilités comprendront :\nLa structuration et le développement du modèle : programmer l'outil sous Python à l'aide de bibliothèques telles que Pandas, Dash et potentiellement Pyomo.\nL'Intégration des variables clés : modéliser des facteurs tels que la fiabilité de l'usine, la pureté du CO2, les contraintes de transport, les options de stockage ainsi que l'usage final.\nUne collaboration transverse : interagir avec les parties prenantes du projet, notamment le chef de projet, le fournisseur de technologies de captage, l'équipe de l'usine Lafarge et le valorisateur de CO2.\nUne méthodologie agile : participer à 3 à 4 sprints agiles, dont les jalons seront alignés sur les revues du projet.\nLa restitution : présenter les résultats et formuler des recommandations à l'ensemble de la communauté CCUS (Carbon Capture, Utilization, and Storage) chez Holcim.\nCompétences clés requises pour ce stage :\nProgrammation en Python, avec une maîtrise particulière de Pandas et de Dash.\nCapacité en modélisation de données et en simulation de scénarios.\nEsprit de résolution de problèmes structuré.\nAptitude à synthétiser des hypothèses techniques et économiques.\nExcellente communication en anglais.\nCapacité à collaborer au sein d'équipes pluridisciplinaires et à distance.\nExpériences valorisées :\nModélisation de procédés industriels ou de systèmes énergétiques.\nParticipation à des projets liés au CO2 ou au CCUS.\nTravail au sein d'équipes de projet transverses en mode distant ou hybride.","description_format":"text","description_chars":2170,"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":["Building Materials"],"lifecycle":[{"event":"open","at":"2026-10-23T16:16:27Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":21,"reasons":["conf:2","velocity","win:early","comp:junior,brand"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/holcim-stage-dingenierie-data-modelisation-hf","json_url":"https://alion.io/job/holcim-stage-dingenierie-data-modelisation-hf.json","meta":{"generated_at":"2026-10-28T02:56:04Z","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":3897,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":448278},"rest":"https://alion.io/mcp/rest/get_company?id=448278"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fholcim-stage-dingenierie-data-modelisation-hf"},{"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%2Fholcim-stage-dingenierie-data-modelisation-hf"},{"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%2Fholcim-stage-dingenierie-data-modelisation-hf"},{"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/holcim-stage-dingenierie-data-modelisation-hf\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fholcim-stage-dingenierie-data-modelisation-hf"}]}
