Electrical Engineer, Production Test

About You & the Role

We are hiring an Electrical Engineer, Production Test to own electrical, functional, and automated test systems that verify Zipline aircraft, dock, delivery pod, and subassembly hardware at scale. Zipline operates safety-critical autonomous aircraft and logistics systems that deliver medicine and essentials across varied field conditions; production test directly affects fleet uptime, field reliability, and customer deliveries. In this role you will lead end-to-end test system delivery for factory floors that support high-throughput manufacturing and rapid product iterations.

You will be expected to prioritize safety, traceability, and measurable improvements in yield and time-to-deploy while working in a fast-scaling production environment with direct consequences for aircraft reliability and delivery network 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 out of Zipline’s South San Francisco manufacturing site (onsite-first with regular floor presence); travel to other Zipline sites or vendor locations may be required for launches and validations.

What You’ll Do

• Develop instrumentation, harnesses, connectors, DAQ, power delivery, and electrical test interfaces with attention to signal integrity, power integrity, and safe measurement.
• Debug PCBA-level failures and product communications, establish electrical and functional pass/fail limits with design and quality partners, and maintain calibration and tester correlation.
• Own design, delivery, and sustainment of production testers and calibration stations from requirements through internal or vendor build, installation, validation, and continuous improvement for aircraft, dock, pod, and subassembly builds.
• Define tester acceptance criteria: test coverage, pass/fail limits, golden-unit strategy, GR&R, capability targets, and production release criteria in partnership with Electrical Design, Firmware, Quality, and Operations.
• Architect and implement electrical and functional testers including harnessing, DAQ, sensors/actuators, power systems, safety interlocks, and mechanical fixtures to meet cycle-time and throughput targets.
• Implement test automation and data pipelines (Python, LabVIEW/TestStand or equivalent) to enable reproducible, high-throughput test flows, data logging, MES/MFG integration, and production dashboards.
• Improve first-pass yield, false-fail rate, tester uptime, utilization, and per-unit cycle time; set targets and report progress monthly.
• Troubleshoot and resolve production escalations on the floor: debug PCBA-level electrical failures, tester instability, fixture issues, SW bugs, and product/tester correlation failures under time pressure.
• Lead cross-functional launches: coordinate requirements, validation plans, training, calibration schedules, spares strategy, and change control with Manufacturing Engineering, Quality, Technicians, Operations, and external vendors.
• Identify and deploy scalable tester architectures and automation that reduce operator steps, minimize touch time, and standardize interfaces across lines.
• Produce and maintain test documentation: test procedures, maintenance/calibration plans, validation records, and change-control artifacts required for production readiness and traceability.

What You’ll Bring

• 2+ years building production test systems, automated test equipment, or end-of-line testers for electro-mechanical or mechatronic products; demonstrated ownership of multiple shipped tester programs.
• 5–7 years of relevant experience preferred.
• BS in Electrical, Mechatronics, Mechanical, Computer Engineering, or equivalent experience.
• Deep practical skills in instrumentation, signal measurement, power delivery, harnessing, connectorization, sensor/actuator interfaces, and PCBA debug with hands-on shop-floor experience.
• Strong test automation experience: Python preferred; experience with LabVIEW, TestStand, or embedded test frameworks and integrating DAQ, scopes, DMMs, power supplies, and electronic loads.
• Proficiency with embedded/product interfaces (CAN, UART, Ethernet, I2C, SPI, USB) and strategies for validating communications and firmware-hardware interactions.
• Track record of delivering measurable production improvements (first-pass yield, cycle time, false-fail reduction, tester utilization, GR&R) and owning metrics reporting.
• Experience working directly on manufacturing floors during launches and escalations; willing to spend significant onsite time supporting shifts, debugging, and qualifying equipment.
• Comfortable with frequent cross-functional coordination and leading vendor builds, FAT/SAT, and production qualification activities.
• Must-have traits: rigorous attention to safety and traceability, decisive technical judgment under production pressure, practical hands-on test/debug capability, and insistence on measurable outcomes.

First-Year Success

• Deliver and validate production tester programs with documented acceptance criteria and production-release evidence.
• Reduce false failures and improve first-pass yield, cycle time, and tester uptime for supported lines.
• Sustain traceable, repeatable test execution and report progress against agreed production goals.
