Senior Software Engineer, Commerce Platform

About Zipline Zipline is the world’s largest and most experienced drone delivery service. We are on a mission to serve all humans equally by ensuring access to food, medicine and essential goods anytime, anywhere. We design, build, and operate the world’s largest autonomous logistics system, delivering critical supplies quickly and reliably. Today, Zipline operates on four continents, makes a delivery somewhere in the world every 30 seconds, and has completed millions of deliveries to date, including blood, vaccines, medical supplies, food, and retail products. Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations. Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe. We operate at a global scale and are looking for practical problem solvers who thrive on real-world challenges and rapid growth. Our team is motivated by building systems that have a direct, meaningful impact on people’s lives and by scaling the future of logistics. We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record breaking speeds. The Commerce Platform team builds the commercial engine that makes that network a real business. We create the tools and integrations partners use to run their business with Zipline, the marketplace logic that connects demand to supply, and the financial infrastructure that ensures every transaction is correct and every dollar is traceable. This platform needs to scale across metros, countries, and verticals (restaurants, retail, and healthcare) handling millions of orders per day. What you will own You will own software across the full commercial stack, including: Merchant Portal - the web portal partners use to manage their Zipline business day to day Partner integrations - Point of Sale connectors, API integrations, and data feeds that connect merchant systems to the Zipline platform Marketplace Platform - internal tooling that controls how demand is prioritized, priced, and distributed across the network Billing Engine - the financial backbone that manages payments, commissions, settlements, and revenue flows across the marketplace Fulfillment apps - mobile and cloud applications for picking and loading execution at partner locations Customer support tooling - AI-powered support systems integrated with order, delivery, and billing infrastructure Serviceability & coverage tools - internal platforms for understanding and modeling where Zipline can serve customers Hard Problems, Real Ownership Most software roles optimize a single surface. The Commerce Platform spans consumer product, marketplace logic, partner tooling, fulfillment, and financial infrastructure. You will work on problems like: How do we give merchant partners real-time operational visibility, self-serve onboarding, and financial clarity without fragmenting the system across verticals? How do we design marketplace policy controls that let operators safely change pricing, capacity allocation, and prioritization, with experimentation before production? How do we build a billing engine that traces every dollar from customer charge through partner payout across promotions, refunds, revenue shares, and multi-jurisdiction tax? How do we build AI-powered customer support that can actually take action, issuing refunds, applying credits, explaining delays using live mission data, rather than just surfacing information? How do we keep unit economics visible and margin protected as volume scales across partners, v
