AI Platform Engineer based in Portugal. This listing is on behalf of a partner company. The partner is seeking an AI Platform Engineer based in Portugal to design and build the foundation of an AI-native operating environment used across a global organization. You will create scalable infrastructure that enables intelligent agents to operate reliably, securely, and transparently. The role combines advanced AI engineering, platform development, governance, and automation to solve complex operational challenges. You will own the architecture, execution layer, evaluation systems, and tooling required to make AI workflows trustworthy. In a fully remote and highly autonomous environment, you will influence how teams adopt and benefit from AI at scale. This opportunity is ideal for an engineer who enjoys building foundational systems, solving open-ended problems, and shaping the future of AI-powered work. Responsibilities include building and operating the infrastructure that enables reliable, measurable, and governed AI systems across the organization. Design, build, and maintain the AI execution platform: event-triggered workflows, model-agnostic runtimes, durable state management, human review processes, rollback mechanisms, and run logging. Own architectural decisions to bring AI agent systems to production and ensure scalable operation. Develop the evaluation layer to ensure AI systems are safe, accurate, and production-ready. Create golden test suites, behavioral evaluations, safety checks, and CI gates to prevent unreliable AI capabilities from deployment. Build and manage
