Controls Engineer, Production Equipment

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 Controls Engineer, Production Equipment based at Coop, Zipline’s South San Francisco manufacturing site, you will develop and integrate the controls and electrical interfaces that make production fixtures, workstations, and automated equipment operate safely and repeatably. You will translate assembly and test requirements into equipment sequencing, interlocks, sensor and actuator interfaces, and fault diagnosis for aircraft, battery packs, docks, and flight-critical subsystems. You will work closely with mechanical and test partners through build, acceptance, commissioning, and production support.

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.

• Develop and validate equipment sequences, interlocks, sensor and actuator interfaces, and fault-recovery behavior against assembly requirements and safety criteria.
• Diagnose control and electrical-interface faults during build, acceptance, and production ramps; coordinate changes with mechanical, manufacturing, and test engineers.
• Own controls and electrical-interface delivery for production equipment from requirements through vendor build, commissioning, and production release; partner with mechanical engineers on CAD (Siemens NX), detailed drawings, and integrated equipment acceptance.
• 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.
• Develop and integrate the controls for 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.
• Apply controls and interface standards and collaborate on 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.

• 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 at Coop, 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.

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