We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record breaking speeds.

About You & the Role Zipline’s Manufacturing Engineering team delivers the production systems that turn autonomous delivery aircraft and their subsystems into reliable, repeatable products at scale. As a Mechanical Engineer, Production Equipment based in South San Francisco, you will own design and deployment of fixtures, workstations, mechanical tooling, and end-of-line test equipment that directly enable aircraft assembly, battery integration, dock components, and flight‑critical subsystems. Your work determines throughput, first-pass yield, assembly cycle time, and maintenance uptime for production lines that supply field operations and live delivery fleets; mistakes affect fleet readiness and safety-critical performance. This opening sits within our manufacturing engineering team; the exact focus will reflect your strengths and the team’s needs. This role is based in South San Francisco, with regular on-site presence during manufacturing shifts. Occasional evening or weekend commissioning and up to 15% travel to vendor or field sites may be required. What You’ll Do

• Own equipment and tooling projects from requirements, Siemens NX CAD, and detailed drawings through vendor fabrication, build, commissioning, and production release.
• Design alignment fixtures, press and torque tooling, ergonomic stations, error-proofing devices, handling fixtures, and automated end-of-line test rigs.
• Apply tooling standards, GD&T, tolerance analysis, and material and process selection to safe, maintainable equipment.
• Lead hands-on debugging and root-cause analysis during launches and production ramps, then validate durable improvements.
• Coordinate equipment scope, test requirements, and schedules with Design Engineering, Manufacturing, Quality, Supply Chain, Test, and Field Operations.
• Write technical RFQs, evaluate proposals, verify vendor quality, and perform acceptance testing before and after installation.
• Target tooling availability above 95%, station-level manual assembly cycle-time reductions of 20–40%, and at least 10% improvement in first-pass yield on targeted assemblies within the first 6–12 months of deployment.

What You’ll Bring

• 5+ years designing production equipment, fixtures, or custom automation in a high-volume or rapidly scaling manufacturing environment.
• A bachelor’s degree in Mechanical Engineering or equivalent practical experience.
• Strong command of GD&T, tolerance analysis, mechanisms, material selection, and failure-mode thinking.
• Proficiency in 3D CAD; Siemens NX is preferred. SolidWorks or Creo experience is acceptable with a strong commitment to learning NX.
• Hands-on fabrication, build, commissioning, debugging, testing, and operator-training experience.
• Practical knowledge of pneumatics, actuators, sensors, linear motion, guarding, and industrial electrical interfaces.
• Experience coordinating vendor builds, validating equipment against drawings and quality criteria, and delivering measurable improvements in cycle time, uptime, yield, or cost.
• Strong ownership, sound judgment under pressure, and a commitment to safety and reliability

Nice to Have

• 5–7 years of relevant experience preferred.
• Experience with aerospace, drones, medical devices, or safety-critical electro-mechanical products is strongly preferred.
