Senior RF Desense Engineer

About Zipline

Zipline is the world’s largest and most experienced drone delivery service. We are on a mission to serve all humans equally by ensuring access to food, medicine and essential goods anytime, anywhere. We design, build, and operate the world’s largest autonomous logistics system, delivering critical supplies quickly and reliably. 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.

Zipline is seeking a Senior RF Desense Engineer to lead the architecture, analysis, mitigation, validation, and long‑term improvement of RF desense performance across our autonomous aircraft and ground infrastructure.

You will own receiver desense engineering from early system architecture through hardware integration, validation, manufacturing, certification, and field deployment. You will work across wireless platforms supporting 4G LTE, 5G , GNSS, Wi‑Fi, ADS‑B, UAT, Bluetooth, ISM radios, emerging Vehicle‑to‑Vehicle (V2V) communications, and future air‑to‑ground communication systems
, ensuring receivers maintain robust performance despite increasingly dense RF and electronic environments.

This role also owns the end‑to‑end electromagnetic shielding architecture across Zipline's wireless platforms. You will define shielding strategies spanning RF integrated circuits, front‑end modules, connectors, cable harnesses, line‑replaceable units (LRUs), subsystem enclosures, and complete products to control both internally generated and externally coupled interference. Working closely with electrical, mechanical, antenna, manufacturing, reliability, and systems teams, you will develop scalable shielding solutions that enable simultaneous operation of multiple high‑power transmitters and high‑sensitivity receivers—including precision GNSS systems—while meeting aggressive performance, reliability, manufacturability, weight, cost, and product lifetime requirements.

While the primary focus of this role is receiver desense, you will also support broader RF coexistence efforts by contributing to system‑level interference analysis, radio scheduling strategies, and multi‑radio integration. You will collaborate closely with antenna, RF front‑end, electrical, embedded software, systems, mechanical, flight test, manufacturing, reliability, certification, and cloud engineering teams to ensure Zipline's wireless systems perform reliably under real‑world operating conditions.

• Own RF desense architecture, analysis, mitigation, validation, and production support across Zipline aircraft, docks, droids, Zipping Points, and future autonomous logistics platforms.
• Develop receiver desense budgets and performance requirements for next‑generation wireless platforms.
• Identify and mitigate receiver sensitivity degradation caused by onboard transmitters, switching power supplies, processors, high‑speed digital interfaces, displays, motors, power electronics, and other electronic subsystems.
• Analyze conducted and radiated interference…
