Senior Embedded Software Engineer, Long Range Platform

About You and the Role

As a Senior Embedded Software Engineer, you will help build the software foundation for some of the most critical systems on our aircraft. This role is well suited for an engineer who is excited to work close to the hardware, move fluidly across different embedded environments, and take ownership of complex problems from early prototype through field-ready deployment.

You are a strong software engineer first, with deep curiosity about how systems behave in the real world. You are comfortable working across a range of platforms, whether that means writing low-level firmware, developing within an RTOS, or building software for embedded Linux systems. You enjoy debugging difficult issues, especially at the boundary between software, hardware, and system behavior, and you bring a thoughtful, methodical approach to getting to the root cause.

This is a role for someone who thrives in a fast-moving, highly collaborative environment. You are energized by ambiguity, eager to learn new domains quickly, and willing to jump in where needed to help the team move faster. You care about building robust, reliable systems, but you also know how to balance rigor with pragmatism in order to make progress.

Most importantly, you are motivated by the mission. You want to work on meaningful technology, contribute to a small and high-impact team, and help build systems that support Zipline’s long-range platform and broader delivery network.

What You'll Do

• Build the embedded software that runs critical flight and safety functions across our aircraft’s microcontrollers and embedded Linux edge computers.
• Improve the reliability of the flight software system end to end by partnering closely with hardware, systems, and cross-functional engineering teams on fault management, validation, and hardware-in-the-loop testing.
• Use flight data and runtime analysis to understand system behavior in the real world, improve confidence in performance, and optimize software where it will have the greatest impact.
• Create the metrics, monitoring, and debugging infrastructure needed to support safe, scalable deployment in the field.
• Develop tools and test capabilities that accelerate early-stage evaluation of new sensors, communication systems, and microcontroller platforms.
• Jump into ambiguous, cross-functional problems and help turn early ideas and prototypes into dependable systems that can scale with the network.

What You'll Bring

• Strong software engineering fundamentals, with proficiency in at least one strongly typed language. We use C++, Rust, and Python.
• Curiosity, adaptability, and a willingness to learn across a wide range of embedded environments, from bare metal and RTOS-based systems to embedded Linux
• Experience building and maintaining real-world deployed embedded systems, and handling the long tail of edge cases to ensure consistent safety, reliability and high performance
• A systems mindset and strong debugging instincts; you know how to break down ambiguous problems and methodically narrow in on root causes.
• Fluency at the hardware/software interface, including bringing up peripherals from schematics and datasheets and debugging prototype hardware.
  Motivation to thrive in a fast-moving, startup environment where engineers wear multiple hats, move quickly, and help shape both the product and the way the team works.
• A mission-driven mindset and excitement for building technology that expands access, improves lives, and supports Zipline’s global delivery network.
  Willingness to work regularly from our South San Francisco headquarters, typically 3–4 days per week, to support close cross-functional collaboration.
