Efficio is the world’s largest procurement consultancy, but we are transforming into a technology-first company.     We are moving from "data-based" to "data-driven," building the intelligent backbone that will power our new GenAI and LLM products.     You won’t just be moving data from A to B; you will be architecting the engine that allows us to integrate AI into the core of our business. This is a chance to use your engineering skills to make global supply chains more sustainable, ethical, and efficient.      Our Engineering culture We trust our engineers to drive architectural decisions and own the platform's strategic direction, from selecting orchestration patterns to final deployment.
