Ils devront garantir une haute disponibilité, une intégrité stricte des données et une intégration fluide au sein de notre écosystème existant.\nMissionsDéveloppement de bout en bout : prise en charge du cycle complet de développement des nouveaux outils, incluant la conception de l’architecture, le développement des API et l’implémentation de la logique métier en Java et avec le framework Spring (Spring Boot, Spring Data, etc.).\n\nStratégie et exécution de la migration de données : conception et réalisation de la migration des données historiques vers les nouvelles structures de référentiels. Cela comprend le mapping des données, leur nettoyage, leur transformation via des processus ETL, ainsi que leur validation afin de garantir l’absence de perte de données et la cohérence globale.\n\nIntégration et interopérabilité : garantir que les nouveaux référentiels puissent être consommés par les applications CIB en aval, via des API robustes ou des files de messages.\n\nSupport de production et stabilité : assurer le support après mise en production, incluant la correction des anomalies, l’optimisation des performances et la garantie de la stabilité de l’environnement de production.\n\nDocumentation : fournir la documentation technique nécessaire : spécifications d’API, schémas d’architecture, dictionnaire de données et procédures de migration.\n\nProfil recherché\nOutils et environnementLangages / Frameworks : expertise avancée en Java, sur des versions récentes, et dans l’écosystème Spring.\n\nGestion des données : solide expérience des bases de données relationnelles (SQL) et/ou NoSQL, ainsi qu’une expérience des projets complexes de migration de données.\n\nArchitecture : maîtrise des architectures microservices, des API RESTful et des design patterns.\n\nDevOps / Outils : maîtrise des pipelines CI/CD, de Git et des frameworks de tests unitaires et d’intégration tels que JUnit et Mockito.\n\nLangue : un niveau d’anglais professionnel courant est indispensable. Le développeur devra être en mesure d’évoluer dans un environnement international et de rédiger la documentation technique en anglais.","description_format":"text","description_chars":2404,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T12:33:56Z"}],"visa":[],"liveness":{"score":65,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.846,"p_room":0.9,"age_days":20,"expected_fill_days":34,"reasons":["seen:20","velocity","win:mid","comp:brand"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/visian-senior-software-engineer-data-referentiel","json_url":"https://alion.io/job/visian-senior-software-engineer-data-referentiel.json","meta":{"generated_at":"2026-10-26T17:12:22Z","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":23066,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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":3908419},"rest":"https://alion.io/mcp/rest/get_company?id=3908419"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvisian-senior-software-engineer-data-referentiel"},{"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%2Fvisian-senior-software-engineer-data-referentiel"},{"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%2Fvisian-senior-software-engineer-data-referentiel"},{"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/visian-senior-software-engineer-data-referentiel\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvisian-senior-software-engineer-data-referentiel"}]}
