Today, Zipline operates on four continents, makes a delivery somewhere in the world every 30 seconds, and has completed millions of deliveries to date, including blood, vaccines, medical supplies, food, and retail products.

Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations.

Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe.

We operate at a global scale and are looking for practical problem solvers who thrive on real-world challenges and rapid growth. Our team is motivated by building systems that have a direct, meaningful impact on people’s lives and by scaling the future of logistics. We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record breaking speeds.

About the Role

Zipline is seeking a senior-level electrical engineer to lead the design and development of high-performance power electronics systems that support our drone charging and docking infrastructure.

The Ground Systems team at Zipline is in charge of all the infrastructures on the ground supporting our autonomous delivery drones with automatic docking, battery charging, thermal management, ground communication and preflight check. This role is central to enable our next generation of drone logistics, solving complex challenges in power distribution, power conversion, battery charging, high performance microprocessor, high-speed network communication and system-level integration. You'll bring deep technical expertise in power electronics to help shape Zipline’s global infrastructure as we scale.

In addition, you’ll work closely with cross-functional engineering teams to own the electrical system development from concept to production. This is a hands-on engineering role, ideal for someone who wants to push the limits of hardware in the real world.

What You’ll Do

Own the electrical design of Zipline’s drone charging systems for volume production through a full design cycle including requirements, prototype, schematic capture, layout, and validation.
Shape the architecture of Zipline’s next generation product, making impactful design decisions daily, while working with a high level of independence.
Lead trade studies, understand competing design priorities, and provide direction and clarity for burning down risk.
Proactively seek out opportunities for improvement in system and component level design.
Collaborate cross-functionally with reliability, mechanical, embedded, and systems engineers in all stages of development, including:

Concept: System requirement, specification, tradeoff
Design: Schematic capture, PCB layout, system integration
Validation: Function and reliability test
Production: DFM, design drawings, manufacturing, EOL test, certification
Deployment: Troubleshoot field issues, develop rapid mitigations, roll learnings into future design revisions
Travel occasionally to support supplier and manufacturer visit, product deployment, and field validation

What You’ll Bring

Bachelor’s or Master’s in Electrical Engineering or related discipline
5+ years of hands-on experience designing and testing power electronics hardware (AC-DC, DC-DC, battery charging, etc.)
Strong understanding of high-voltage power semiconductors like SiC or Si MOSFETs
Deep knowledge of circuit topologies for AC-DC and DC-DC power conversion
Design experience with MCU and digital communications (Ethernet, SPI, I2C, UART)
Proficiency in schematic capture, PCB layout, and simulation tools (Altium, SPICE, etc.)
Familiarity with UL, IEC, and other electrical safety standards
Strong lab skills and familiarity with test equipment like oscilloscope, digital multimeter, power analyzer, LCR meter, function generator, spectrum analyzer, etc
Experience with EMI filter design and inductor/transformer design is a strong plus
Excellent communication and collaboration skills across engineering disciplines
Must be eligible to work in the U.S.
Must be able to work at Zipline’s South San Francisco office.
