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.

About the Role

As a Linux Software Engineer at Zipline, you’ll build and maintain our Yocto-based Linux kernel BSP powering our flight computers, enabling our highly autonomous aircraft to safely fly over millions of homes day-in and day-out. You will work closely with other Linux experts on this team. You will also work closely with software engineers who build user-space applications and drivers. This job also spans the entire development lifecycle, working with the Release team, owning validation, and analyzing performance from real-world flight tests.

Our technical stack is built on embedded Linux, running on three desktop-grade computers with a distributed network of sensors, redundant communication links, and actuators. We are looking for detail-oriented engineers with deep expertise in embedded Linux and distributed systems, including kernel development, userspace tooling, real-time performance tuning, system reliability and core operating systems activities.

What You’ll Do

Design and build the software architecture necessary to run everything from critical flight software to interconnected ground-based hardware on embedded Linux systems
Contribute to the development and maintenance of our custom Linux distribution on Yocto, ensuring a reliable and performant foundation for our flight and ground-based systems
Analyze the runtime characteristics of our Linux-based avionics software in flight to build confidence in its performance, with a focus on system reliability, maintainability, and optimization
Develop and optimize kernel and userspace drivers for production and prototype sensors, and refine sensor data APIs for perception, navigation, and other autonomy software engineers
Develop metrics, monitoring, and troubleshooting capabilities to prepare the system for field deployment at scale
Design and build data collection and testing tools to support early-stage evaluation of new sensors, communications systems, and edge compute platforms

What You’ll Bring

Strong software engineering skills, with proficiency in at least one strongly typed language; we use Rust and C++ onboard, and Python for tooling
Deep expertise in embedded Linux development, including experience with kernel modifications, userspace programming, and performance tuning
Experience working with Yocto or other build systems for custom Linux distributions
Strong software architecture skills, with experience designing and shipping solutions for complex real-world use cases
A systems-oriented mindset, with a focus on reliability, fault tolerance, and performance optimization
Technical leadership skills and experience owning large technical systems that other engineers contribute to
Detail-oriented mindset to think through validating a system’s safety
