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 Mechatronics Engineer, Production Equipment based at Coop, Zipline’s South San Francisco manufacturing site, you will integrate mechanisms, electrical interfaces, sensors, actuators, pneumatics, and controls into reliable production equipment for aircraft, battery packs, docks, and flight-critical subsystems. Your focus will be the interfaces between equipment disciplines, from requirements and build through integrated debugging, acceptance, and safe commissioning on the factory floor.

This is a hands-on individual-contributor role, with direct ownership of equipment design, build, commissioning, and improvement on the factory floor. 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.

What You’ll Do

• Integrate mechanical motion, pneumatics, sensors, actuators, industrial electrical interfaces, and safety interfaces into production-ready tooling and small automation.
• Debug interactions between mechanisms, sensing, actuation, and controls; verify integrated equipment behavior during vendor acceptance and factory commissioning.
• Own end-to-end integration and delivery of production equipment and tooling projects for aircraft and electro-mechanical subsystems: requirements, CAD (Siemens NX), detailed drawings, vendor fabrication oversight, build, commissioning, and production release.
• Deliver measurable improvements: increase tooling availability above 95%, reduce manual assembly cycle time by 20–40% per station, and improve first-pass yield (FPY) on targeted assemblies by at least 10% within the first 6–12 months of deployment.
• Design and install alignment fixtures, press and torque tooling, ergonomic operator stations, poka‑yoke devices, handling/transport fixtures, and automated end-of-line test rigs tied to build and test specs for aircraft, battery packs, and docks.
• Perform on-line debugging and rapid root‑cause analysis during launches and ramp phases; be prepared to run weekend or evening commissioning efforts during critical releases.
• Develop and apply tooling design standards, GD&T practices, tolerance stacks, and material/process selections that meet safety and maintainability requirements for autonomous hardware.
• Coordinate cross-functionally with Design Engineering, Manufacturing, Quality, Supply Chain, Test Engineering, and Field Operations to align tooling scope, test requirements, and production schedules.
• Work directly with fabricators and vendors: write technical RFQs, evaluate proposals, verify vendor QC, and perform acceptance testing at build and after installation.

What You’ll Bring

• 2+ years designing production equipment, fixtures, or custom automation in a high-volume or fast-ramping manufacturing environment.
• Bachelor’s degree in Mechanical Engineering or equivalent practical experience.
• Demonstrated mastery of GD&T, tolerance analysis, mechanism design, material selection, and failure‑mode thinking for assembly tooling.
• Proficiency in 3D CAD; Siemens NX preferred (SolidWorks/Creo experience acceptable with strong NX learning intent).
• Hands-on experience commissioning equipment on the factory floor: supporting fabrication, build, debug, test, and operator training; comfortable spending most of your week on-site.
• Practical knowledge of pneumatics, actuators, sensors, linear motion, machine guarding, and industrial electrical interfaces used in tooling and small automation.
• Track record delivering quantitative outcomes (cycle time, uptime, FPY, cost per unit) and making trade-offs between throughput, reliability, and maintainability.
• Ability to coordinate vendor builds and perform acceptance testing to technical drawings and QA criteria.
• Logistics: role is site-based out of Zipline’s South San Francisco manufacturing site; expect regular on-site presence during standard manufacturing shifts, availability for occasional off-hours commissioning, and up to 15% travel to vendor or field sites.
• Must-have traits: high ownership of safety and reliability, decisive technical judgment under schedule pressure, comfort with ambiguity and rapid iteration, and willingness to escalate and resolve issues that affect fleet readiness.

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.
