Senior Billing & Sales Administrator (ADV)

📍 Paris | Full-time | Fluent 🇫🇷 & 🇬🇧   At Bigblue, we're building the logistics backbone for the next generation of commerce. Modern brands sell everywhere: through their own online stores, marketplaces, retail, social commerce, and more. Across every channel, customers expect the same fast, reliable, and transparent experience after they buy. What used to be Amazon's exclusive advantage is now becoming the standard for every ambitious brand. We're helping them get there. Since 2018, we've built a tech-driven fulfilment platform used by 600+ brands, including Muji, Aigle, Scuffers, and Cabaïa. With 200+ Bigbluers across the UK, France, Spain, and Germany, our proprietary tech stack, and a network of 9 warehouses and over 100,000 sqm of fulfilment space across Europe, we ship millions of orders every month. And we're nowhere near done! Backed by €20M+ in funding, we're expanding across Europe and building the operating system that will power modern commerce operations at a global scale. At Bigblue, we hold ourselves to a very high bar: in the quality of our product, the rigour of our operations, and the care we bring to every merchant we work with. You'll be working alongside talented people on real, high-impact problems, in an environment where high standards come with genuine support, ownership, and room to grow. If you want your work to matter from day one, you're in the right place.     As Finance Manager, you will join a finance team in full structuration and take ownership of a 360 scope spanning accounting supervision, FP&A, billing, financial analysis and controlling across our entities (France, Spain, UK, Germany). You will work closely with our external partners, all Bigblue internal teams, and senior leadership (CFO, co-CEOs) to ensure accurate, timely reporting and to support decision-making in a fast-moving environment. Success will be evaluated based on your ability to handle a wide range of topics, the reliability and timeliness of our monthly and annual closings, the quality of our analyses, and your ability to implement automation and a data-driven approach for recurring processes.
