Senior Backend Engineer

DOSS is building an Operations Cloud for the real world. We deliver a modern, AI-native platform that helps physical product businesses manage the flow of goods, dollars, and data across procurement, inventory, orders, fulfillment, and finance in real time. Purpose-built to replace spreadsheet chaos and rigid, consultant-heavy ERP implementations, DOSS delivers fast time-to-value and stays adaptable as a business evolves. Through our Adaptive Resource Platform (ARP) and unified operational data model, teams can deploy quickly, automate workflows, and make changes without months of re-implementation. We recently raised a $55M Series B co-led by Madrona and Premji Invest, with participation from Intuit Ventures, Theory Ventures, General Catalyst, Contrary Capital, and Pathlight VC. DOSS is trusted by fast-growing operators to run critical operations with speed, control, and confidence.
