Does quickly developing multiple iterations of systems to test novel components through the extreme environments demanded of aerospace applications sound like the way you want to spend your time? Do you love designing tests for cross-functional interfaces with little information, full ownership, and the responsibility to make it happen? At Zipline our work is intended for the field. Patients are counting on it today--there is no time for aiming low or coming up short.

If leveraging your talent to drive full vehicle test systems to fruition with a small but dedicated team at your side sounds like your cup of tea, please read on.

• Work with the product design and reliability teams to generate requirements for test systems that accurately capture the intended function of the vehicle while leaving the door open for future automation and high volume capacity.
• Explore and define product edge cases based on data you collect from the field, existing logs, and in anticipation of future use cases and environments.
• Design, build, and maintain critical test systems
• Manage test systems for early stage designs. This will include ruthlessly prioritizing where our efforts must be spent to get the most out of every precious day.
• Provide technical guidance to junior engineers and technicians. Pivot often as we navigate uncertain regulatory space and learn more about what it will take to really wow our customers.

• Design for user experience of mechanical test systems. You can develop a machine that accomplishes complex interactions reliably and can be used by anyone with minimal training.
• Strong mechanical engineering fundamentals. You understand the theory behind good design decisions and have a proven track record of executing these designs to make a test system that is more reliable than the product it is testing.
• Cross functional team management experience such that you can balance the needs of structures, aero, embedded, and software engineering teams to create one product that works for all.
• Understand when we can get away with a quick and dirty or scrappy solution and when it is worth our time and money to make investments in the future.
• Must be eligible to work in the US
• Must be able to work in person at Zipline’s South San Francisco headquarters
