Senior AI Platform Engineer

Job Title: Senior AI Platform Engineer Location: Belgrade Serbia or Lisboa/Porto/Braga, Portugal Working Model: Hybrid (flexible, depending on candidate location) Reports to: sa.global Labs Leaderhip Department: sa.global Labs – Core Team (team working on AI development within sa.global) Seniority Level: Senior empower AI Platform - Senior AI Platform Engineer About the Role Anyone can call an LLM API. We're building the harness around it: sa.global Labs is expanding the core team behind empower — our industry-specific agentic AI platform that fuses a domain knowledge graph, a unified data hub, and multi-agent orchestration to automate real enterprise decisions, not demos. We're looking for a Senior AI Platform Engineer to build and operate the scalable foundation underneath it: the APIs, distributed services, data pipelines, and retrieval infrastructure that connect enterprise data, knowledge, and AI capability across the platform.

It's a deliberately opinionated stack — Neo4j for the Business Knowledge Graph, PostgreSQL with pgvector/pg_search for hybrid retrieval, Prefect for pipelines, LangGraph and DSPy powering the agent layer above you — and this is a hands-on senior role: you're building the reliable, secure, production-grade systems that carry real AI workloads for clients across multiple industries, not prototyping in a sandbox. About empower AI Platform empower is a proactive agentic intelligence layer. It's built around 3 pillars, and this role touches all of them
