Описание

Syone is hiring an Artificial Intelligence Platform Engineer for hybrid work in Lisbon or Porto. The role focuses on designing and operating an enterprise AI platform, integrating multiple LLM providers, building RAG and agent workflows, and owning deployment, evaluation, safety, and governance. It requires strong software engineering experience and production AI delivery.

Responsibilities

Design and operate the enterprise AI platform layer, integrating and managing multiple LLM providers in a production environment
Multi-provider LLM integration across Azure AI Foundry, Azure OpenAI, Claude (AWS Bedrock), and OpenAI APIs — with routing, fallback, and cost controls
Reusable AI services and APIs consumed by agents, copilots, and business applications
Context management, memory architectures, structured outputs, and function calling
Inference performance optimisation, cost attribution, and usage analytics
AI environment management — prompt versioning, model versioning, deployment pipelines
Design and deploy autonomous agents and multi-agent systems that execute real business workflows
Autonomous and planning agents capable of multi-step reasoning over enterprise knowledge
Multi-agent orchestration using Model Context Protocol (MCP) and agent collaboration frameworks
Tool-using agents with function calling, plugin architecture, and enterprise system integrations
AI copilots built on Microsoft Copilot Studio for business users
Workflow automation connecting AI agents to enterprise platforms (SharePoint, Salesforce, M365, etc)
Build enterprise-grade retrieval capabilities on top of the Corporate Brain data platform
Hybrid search (semantic + keyword) with vector indexing and Azure AI Search integration
Context retrieval, citation frameworks, and prompt orchestration for grounded, accurate outputs
Chunking strategies, embedding pipeline consumption, and knowledge grounding
RAG evaluation — precision, recall, hallucination detection, and context relevance testing
Own the quality and safety bar for all AI systems in production
Systematic evaluation frameworks covering accuracy, hallucination detection, and response quality
Prompt regression testing, agent benchmarking, and safety testing across model updates
Guardrails design and implementation — input/output filtering, content policy enforcement
Production monitoring: latency, cost per query, error rates, and agent task completion rates
AI lifecycle governance — structured approval gates before production deployment
