Senior Embedded Software Validation Engineer - Avionics SW

Senior Embedded Software Validation Engineer South San Francisco, California, USA 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. About You and The Role Zipline's autonomous drone delivery system relies on software that behaves safely and predictably. The avionics software team owns the flight computer operating system and platform services, as well as reliable management of the avionics sensor suite. As a Senior Embedded Software Validation Engineer, you will lead validation strategy and execution for avionics components, including the flight computer and its related peripherals, to ensure that software executes reliably and deterministically. Your work will help gather the evidence that exposes capability gains, gaps, regressions, and safety risks, and will serve as the foundation for confidently shipping software releases. What You'll Do • Develop component-level validation strategy for software correctness, reliability, and performance on an Embedded Linux node.

• Design, implement, and execute nominal, stress, and edge-case scenarios from simulation through full-system flight testing.
• Develop and maintain hardware test infrastructure to meet the above objectives.
• Build metrics, visualizations, real-time performance and safety monitors, and automated tools that reveal capability changes and regressions.
• Set validation evidence and exit criteria that inform release, deployment, and operating-domain expansion decisions.
• Debug failures across simulation, hardware, firmware, embedded software, and application software; clearly document findings and escalate unresolved safety or performance risks.
• Partner with test infrastructure teams to increase automated validation coverage, efficiency, and precision while improving confidence in rapid development velocity.

What You'll Bring • Bachelor's or Master's degree in Computer Science/Engineering, Software Engineering, or a related field.

• 5+ years of software development, software systems engineering, or software validation experience with robotic systems.
• Strong experience in one or more relevant domains: Embedded Linux, PREEMPT_RT, firmware / RTOS, safety-critical systems, 802.11, Ethernet.
• Experience developing validation strategies for autonomous robotics.
• Experience root-causing failures in complex autonomous systems.
• Proficiency with Rust or other programming languages used in safety-critical applications such as MISRA C, or C++.
• Familiarity with other programming and query languages such as Python and SQL.
• Experience deriving software safety or performance requirements from functional safety requirements or similar requirements decompositions.
