📍 Madrid | Full-time | Bilingual (🇬🇧 & 🇪🇸) E-commerce is booming — but independent brands still struggle to match the seamless logistics of giants like Amazon. At Bigblue, we’re on a mission to change that. We help brands by democratizing best-in-class operations: scaling faster while delivering a five-star customer experience. Since 2018, we’ve built a tech-driven logistics platform powering 500+ brands — from fast-growing DTC players to global names like MUJI, Aigle, and Cabaïa. With 110+ employees across Paris, Madrid, and London, our proprietary WMS (Warehouse Management System) Atlas, and a network of 7 warehouses across Europe, we’re solving logistics challenges that others haven’t dared to tackle — making fulfillment faster, smarter, and greener. Backed by $20+M in funding and trusted by the next generation of e-commerce leaders, we’re scaling rapidly — from 10 million orders in 2024 toward ambitious enterprise expansion. The journey ahead is bold, and we’re looking for the right partner to help us lead the way. About the role 🚀 This role is focused on Spain, one of Bigblue’s most operationally critical markets today and a key pillar of future network expansion. The Operations Manager will own end-to-end warehouse operations, including performance, cost, capacity, and execution quality, with a strong hands-on presence in the day-to-day operations. This is not a purely strategic role. Bigblue is an execution-driven company, and this position requires being deeply immersed in daily operations, on the warehouse floor, working directly with teams and partners to identify issues and drive improvements in real time.
