Software Engineer, Test Infrastructure
About The Position
Zipline is seeking software engineers to build tools and infrastructure for systems validation and flight testing. The team develops precise, efficient, scalable software solutions to validate aircraft and ground systems at every level. Work ranges from integrating avionics, sensors, actuators, and radios with high-fidelity simulated environments in bench-top Hardware-in-the-Loop (HIL) setups, to building applications that plan, orchestrate, and evaluate thousands of automated nominal and off-nominal real-world flight tests each day. The role develops tools used by cross-functional partners to deliver reliable, flight-ready software. The systems built serve as a final line of defense before hardware and software are deployed globally for real-world deliveries.
Requirements
- At least 4 years of experience in software engineering for complex, hardware-backed, safety-critical systems.
- Extensive experience with Python, specifically using test systems such as pytest.
- Experience testing Rust and/or C embedded systems.
- Extensive experience working with CI/CD.
- Experience developing and executing test plans for complex, safety-critical embedded and cloud software.
- Strong problem-solving skills and ability to quickly learn a new system for testing purposes.
Responsibilities
- Design, develop, and maintain HIL test infrastructure integrating real aircraft hardware with simulated systems and environments.
- Develop software tools, frameworks, and services for large-scale automated and semi-automated system validation.
- Support a high-throughput flight test organization running thousands of tests daily, including targeted regression tests and rare off-nominal scenarios.
- Write and maintain test software, drivers, and interfaces for embedded and Linux-based systems.
- Support test framework architecture designs and improvements.
- Debug complex validation failures spanning simulation, hardware, firmware, and application software.
- Collaborate with flight test engineers, systems engineers, avionics, autonomy, and embedded software teams to define system-level validation strategies.
- Improve test reliability, debuggability, and signal-to-noise as systems and test volume scale.
