Software Engineer - Systems Validation Infrastructure

About the role

Zipline is looking for software engineers to build the tools and infrastructure that power our systems validation and flight test organizations. This team develops precise, efficient, and scalable software solutions used to validate aircraft and ground systems at every level.

What You’ll Do

• Design, develop, and maintain HIL test infrastructure that integrates real aircraft hardware with simulated systems and environments.
• Develop software tools, frameworks, and services to enable large-scale automated and semi-automated system validation.
• Support a high-throughput flight test organization running thousands of daily tests, from targeted regression tests to 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.

What You’ll Bring

• 4+ years of experience in software engineering for complex, hardware-backed, safety-critical systems.
• Extensive experience in Python, specifically using test systems (e.g. pytest).
• Extensive experience working with CI/CD.
• Experience developing and executing test plans for complex, safety critical, embedded and cloud software.
• Strong problem-solving and ability to quickly learn a new system for testing purposes.
