Embedded Software Engineer, Validation

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 are looking for an Embedded Software Engineer to build the automated validation systems that ensure the reliability of the embedded platform powering autonomous aircraft operating in safety-critical environments. This role sits within the Embedded Platform team, which develops the foundational middleware and infrastructure used throughout the flight software stack. Our systems provide critical capabilities including interprocess communication (IPC), logging and observability, communication bridges, over-the-air (OTA) software updates, and live telemetry between aircraft and cloud services.

As an Embedded Software Validation Engineer, you will design and build the simulation and hardware-in-the-loop (HIL) infrastructure used to validate these platform services. Working closely with software engineers across the Flight Software organization, you will develop comprehensive automated test scenarios that verify functionality, performance, reliability, and fault tolerance before software reaches an aircraft. This is a software engineering role focused on building scalable validation infrastructure, not manual testing.

• Design, implement, and maintain automated validation infrastructure for embedded platform software
• Build simulation and hardware-in-the-loop (HIL) test environments that exercise platform services under realistic operating conditions
• Develop automated test scenarios covering core platform capabilities including:
  • interprocess communication (IPC)
  • logging and observability
  • communication bridges
  • over-the-air (OTA) update systems
  • live telemetry and cloud connectivity
• Design tests that validate functionality, reliability, performance, and behavior under fault conditions
• Develop stress, endurance, regression, and fault-injection test suites for distributed embedded systems
• Partner closely with Embedded Platform engineers throughout the software development lifecycle to improve testability and define validation strategies during feature design
• Build tooling for automated test orchestration, execution, reporting, and dashboards
• Contribute to continuous integration pipelines and automated validation workflows
• Investigate failures across simulation, HIL, and production environments to identify root causes
• Occasionally contribute improvements to production embedded software that increase reliability, observability, or testability
• Build automated validation infrastructure that enables engineers to rapidly verify platform changes with confidence
• Increase coverage of simulation and HIL testing across the Embedded Platform stack
• Identify reliability and performance issues before they reach flight hardware
• Improve the observability and testability of core middleware through close collaboration with platform engineers
• Enable the Flight Software organization to move faster while maintaining the reliability expected of safety-critical systems

• Experience developing embedded or systems software
