Senior Software Engineer, Consumer Apps

Do you want to change the world? Zipline is on a mission to transform the way goods move. Our aim is to solve the world’s most urgent and complex access challenges by building, manufacturing and operating the first instant delivery and logistics system that serves all humans equally, wherever they are. From powering Rwanda’s national blood delivery network and Ghana’s COVID-19 vaccine distribution, to providing on-demand home delivery for Walmart, to enabling healthcare providers to bring care directly to U.S. homes, we are transforming the way things move for businesses, governments and consumers. The technology is complex but the idea is simple: a teleportation service that delivers what you need, when you need it. Through our technology that includes robotics and autonomy, we are decarbonizing delivery, decreasing road congestion, and reducing fossil fuel consumption and air pollution, while providing equitable access to billions of people and building a more resilient global supply chain.

Join Zipline and help us to make good on our promise to build an equitable and more resilient global supply chain for billions of people.

Zipline’s Application Software team builds the systems that power every part of our business, from the factory floor to real-time delivery operations. We are responsible for the “operating system” of Zipline: critical applications that manage hardware production and inventory, fuel demand generation and customer engagement, enable data-driven decision making, and orchestrate fulfillment, flight, and delivery at scale. Our work spans internal platforms that streamline manufacturing, supply chain, and financial workflows, as well as external-facing applications that allow customers to place and track orders. By connecting every corner of the business through software, we ensure Zipline can operate efficiently, intelligently, and globally.
