Mechanical Test Equipment Design Engineer, Crash Safety
About The Position
Zipline builds autonomous delivery aircraft and ground systems that operate daily in demanding field environments. Safe products begin with rigorous validation. As a Mechanical Test Equipment Design Engineer focused on Crash Safety, you will develop the custom equipment that enables engineers to evaluate structural integrity, crashworthiness, battery safety, and failure modes under extreme loading conditions. The Battery & Power Electronics team is responsible for ensuring our energy storage systems remain safe throughout their lifecycle—including impact, crush, abuse, vibration, thermal, and post-crash events. You will design and build robust mechanical test equipment that reproduces these conditions safely, accurately, and repeatably, accelerating product development while generating the engineering evidence needed to make confident design decisions. This role is open to engineers at all levels. Responsibilities and technical scope will be matched to your experience and demonstrated ability, with opportunities to grow from owning individual fixtures and mechanisms to leading the architecture of complex validation systems and laboratory infrastructure.
Requirements
- Experience designing mechanical systems, structural equipment, automated machinery, manufacturing equipment, or engineering test equipment appropriate to your career level.
- Strong mechanical design skills using NX, SolidWorks, or equivalent CAD software.
- Strong engineering fundamentals including machine design, structural analysis, GD&T, tolerance analysis, hand calculations, bolted joints, fatigue, material selection, and design for manufacturing.
- Experience performing structural analysis using hand calculations and FEA.
- Familiarity with hydraulic, pneumatic, servo-electric, or other high-force actuation systems.
- Experience designing welded structures, machined assemblies, and fabricated equipment.
- Hands-on experience assembling, commissioning, troubleshooting, and improving mechanical equipment.
- Demonstrated ability to collaborate across multidisciplinary engineering teams and communicate technical tradeoffs effectively.
Nice To Haves
- Experience supporting crash, impact, abuse, structural, environmental, or durability testing is preferred.
Responsibilities
- Own end-to-end development of crash safety equipment from requirements → concept → design → fabrication → commissioning → validation → continuous improvement.
- Design and develop custom mechanical test equipment supporting impact, crush, penetration, drop, abuse, fire, vibration, and structural testing of batteries and aircraft hardware.
- Design structural frames, fixtures, reaction structures, containment systems, mounting interfaces, and mechanisms capable of safely supporting high-energy testing.
- Develop systems utilizing hydraulic, pneumatic, servo-electric, and mechanical actuation to apply controlled static and dynamic loading.
- Perform engineering analyses including hand calculations, tolerance stacks, bolted joint design, load path analysis, FEA, fatigue assessments, and failure mode evaluations to ensure equipment performance and operator safety.
- Produce CAD assemblies, detailed drawings, GD&T, bills of materials, and manufacturing documentation for fabricated and machined assemblies.
- Design equipment with operator safety as a primary requirement, incorporating guarding, interlocks, energy isolation, debris containment, fire mitigation, and ergonomic considerations.
- Partner with electrical, controls, and software engineers to integrate instrumentation, sensors, data acquisition, and automation into mechanical test systems.
- Build, commission, troubleshoot, validate, and continuously improve laboratory equipment to maximize safety, repeatability, throughput, and maintainability.
- Support crash safety, abuse, and structural validation campaigns by rapidly developing new test capability and modifying existing equipment.
- Work closely with Mechanical Design, Reliability, Systems Engineering, Manufacturing, Integration & Test, and Safety teams to translate validation requirements into practical engineering solutions.
- Lead supplier engagement for fabricated equipment, machined components, welded structures, hydraulic systems, and custom mechanical assemblies.
Benefits
- medical, dental and vision insurance
- paid time off
