Required Skills
CAD

Requirements
  • Proven track record owning complex subassemblies or full systems over at least 3 product programs (concept, prototype, validation, production)
  • Strong fundamentals: load estimation, classic mechanics, structural hand calcs to guide part sizing, finite element analysis and clean CAD designs
  • Excellent problem solving - you are tenacious and scientific in your approach while able to quickly explain concepts to others
  • Familiarity with mechanism design and the integration of electrical components into hardware products
  • Practical knowledge of manufacturing methods such as welding, sheetmetal forming, extrusion, CNC machining, etc
  • Experience partnering with contract manufacturers to ramp up production of high volume lines
  • Demonstrated CAD fluency for system level ownership - 20-50 parts simultaneously in 3D/2D
  • Disciplined processes: parts are released, BOMs are maintained, SOPs created for builds, and timelines are up-to-date
  • You have true expertise in one area that will level up the team
  • Excellent communication - written, verbal, and visual. You know how to tailor to your audience with the right level of technical depth to be as effective as possible, including using basic tools in place of full CAD when it makes sense
  • Bachelor’s degree in Mechanical Engineering
  • Ability to periodically (<10%) travel to visit customers and suppliers
  • Must be eligible to work in the US and willing to relocate to Bay Area CA region
Responsibilities
  • Own the design of the entire system and subassemblies for the next generation of the towers, including design of structural components, mechanisms, and electronics integration
  • Make important decisions about the product architecture and create designs that will enable practical scale on a short timeline that will meet high product reliability targets
  • Quickly iterate and downselect based on data from analysis and test results from your prototypes
  • Collaborate cross functionally with electrical, software, civil, NPI and supply chain teams to bring your designs to production and into the field
  • Use engineering fundamentals to develop innovative products for ground systems infrastructure centered around welded steel towers that are a few stories high
  • Solve complex problems with little direction and maximum autonomy; rely on hand calculations to guide thinking and part sizing
Desired Qualifications
  • NX is your primary CAD tool
  • Knowledge in applying appropriate FOS and margin to human safety critical application (design margin tables, structural joint calculations)
  • Hands-on welding experience for prototyping

Zipline designs, builds, and operates autonomous delivery networks using two drone platforms: P1 fixed-wing drones for long-range, centralized deliveries with parachute drops, and P2 hover-drones for precise home deliveries. It provides end-to-end service, from drones and hubs to software and logistics, under government and enterprise contracts, earning revenue per delivery or per distribution center. The system enables zero-emission, instant logistics for medical supplies and consumer goods across multiple countries, with partners like Walmart and GNC. The goal is fast, reliable, scalable delivery that expands access to essential items, especially healthcare, through a fully integrated global network.
