platform engineer for AI infrastructure

Описание: Langdock is an AI platform used by more than 10,000 companies to provide secure access to leading AI models, build and share agents, and automate repetitive workflows.

The platform is designed for European enterprises while preserving control over data, model providers, and deployment environments.

• Задачи
• Own shared platform capabilities as internal products, including their interfaces, reliability, evolution, and long-term operation;
• Turn model access, agent execution, authorization, queues, integrations, document processing, and sandboxed compute into stable, reusable building blocks;

• Define service APIs and failure behavior;
• Plan migrations, implement and deploy services, make them observable, and respond to production failures;
• Work with Systems Engineers on underlying mechanisms while remaining accountable for service boundaries and lifecycles;
