Tu seras responsable de la conception et de l'exploitation de la couche API Gateway de notre plateforme. Tu travailleras en étroite collaboration avec l'équipe d'inférence et les premiers clients. Ce poste est à la frontière entre le backend et l'infrastructure, et nécessite une expérience significative en développement backend orienté APIs à fort trafic, ainsi qu'une maîtrise de Go et/ou Python.\nMissions\nConcevoir et opérer la couche API Gateway de la plateforme, en assurant l'exposition des endpoints d'inférence, la gestion du routage, le rate limiting, l'authentification, l'accounting et l'autorisation.\nTravailler en lien étroit avec l'équipe inférence et les premiers clients pour garantir une API fiable, avec une latence maîtrisée, qui réponde aux exigences de souveraineté et de conformité.\nUtiliser des technologies telles que Go et/ou Python, JavaScript/TypeScript, Kubernetes, service mesh, OpenTelemetry, Prometheus/Grafana, PostgreSQL pour le développement backend orienté APIs.\nProfil recherché\nIndispensables : \n- Expérience significative en développement backend orienté APIs à fort trafic\n- Maîtrise de Go et/ou Python en contexte production + JavaScript/TypeScript apprécié \n- Bonne compréhension des contraintes d'une passerelle API (routing, rate limiting, auth, accounting) \n- Kubernetes : déploiement, networking, service mesh \n- Culture sécurité API : authentification, autorisation, secrets management, standards OWASP \n- Observabilité : OpenTelemetry, Prometheus, Grafana ou équivalent \nUn plus : \n- Expérience API Gateway (Kong, Envoy, custom) ou reverse proxy à l'échelle\n- Sensibilité aux exigences souveraines (SecNumCloud, ISO 27001) \n- Expérience avec des workloads GPU ou inférence ML côté infrastructure \nCe qui fait la différence : quelqu'un qui a construit une couche d'intégration entre une plateforme technique complexe et des clients exigeants, et qui sait tenir la charge.","description_format":"text","description_chars":1983,"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
