Lead design, delivery, and sustainment of production testers and calibration stations for aircraft, dock, pod, and subassemblies. Architect electrical/functional testers, implement test automation and data pipelines, define acceptance criteria, debug PCBA-level failures on the floor, and drive measurable improvements in yield, false-fail rate, cycle time, and tester utilization while coordinating cross-functional launches and vendor qualifications.

Lead and grow the Marketplace engineering organization building consumer and partner-facing marketplace products, integrations, pricing and fulfillment tools. Set technical and product strategy, drive architecture and platform decisions, manage technical debt, partner with product, and create operating rhythms to scale a high-velocity engineering organization.

Investigate and reproduce electrical and mechanical failures on flex circuits, PCBAs, connectors, and assemblies. Troubleshoot with lab equipment, analyze telemetry and test data, perform physical inspections (microscopy, X-ray), run experiments, determine root causes, recommend and verify corrective actions, and document findings in clear reports while partnering with cross-functional teams.

Lead and scale Zipline's global Strategic Sourcing organization: define sourcing strategy for all direct materials, manage supplier relationships and negotiations, drive cost, quality, delivery and risk management, build sourcing governance, and partner cross-functionally to enable product development and global production.

Lead development and validation of physics-based electric propulsion models across fidelity levels. Design and run experimental characterization campaigns, drive quantitative trade studies, build modular modeling frameworks, and continuously improve models using lab and flight data. Collaborate closely with electrical, mechanical, thermal, controls, test, manufacturing, and operations teams to inform hardware design, operating limits, thermal management, and control strategies.

As an Embedded Firmware Engineer, you'll design and build critical flight software for drones, ensuring reliability and performance while collaborating with various engineering disciplines.

Manage onsite inventory control and material flow for test facility: receive, inspect, and put away parts; execute ERP/WMS transactions; perform cycle counts; pick, stage, and deliver parts; process returns; monitor demand and initiate replenishment; coordinate shipments and cross-functional material risk mitigation.

Lead and grow a software engineering team building marketplace management tools and services. Own roadmap and execution, partner with Product and Operations, improve architecture for scale, and deliver reliable, operationally-focused customer-facing software while hiring, coaching, and developing top engineers.

Own PCB layout execution in Altium from schematic handoff through fabrication and assembly release. Create layouts for mixed-signal, power, and high-speed boards; define stack-ups and layout rules; collaborate with electrical, mechanical, and manufacturing teams; generate fabrication and assembly outputs; resolve DFM/DFA issues; and improve layout standards and release workflows to support prototype and production builds.

Lead supplier qualification and industrialization of electric motors for drones. Manage supplier readiness, APQP/PPAP/PFMEA/SPC activities, DFM/DFA reviews, validation, cost and quality improvements, manufacturing transfers, and cross-functional launches with ~50% travel across Japan and Southeast Asia.
