About Zipline

Do you want to change the world? Zipline is on a mission to transform the way goods move. Our aim is to solve the world’s most urgent and complex access challenges by building, manufacturing and operating the first instant delivery and logistics system that serves all humans equally, wherever they are. From powering Rwanda’s national blood delivery network and Ghana’s COVID-19 vaccine distribution, to providing on-demand home delivery for Walmart, to enabling healthcare providers to bring care directly to U.S. homes, we are transforming the way things move for businesses, governments and consumers.

The technology is complex but the idea is simple: a teleportation service that delivers what you need, when you need it. Using robotics and autonomy, we are decarbonizing delivery, decreasing road congestion, and reducing fossil fuel consumption and air pollution, while providing equitable access to billions of people and building a more resilient global supply chain.

Join Zipline and help us to make good on our promise to build an equitable and more resilient global supply chain for billions of people.

About the Role

As a Field Reliability Engineer at Zipline, you will be responsible for measuring, analyzing, and communicating the real-world reliability and economic performance of our deployed drone-delivery systems. You combine experience in data analysis with a working knowledge of Bayesian and classical reliability statistics, applying them pragmatically to the physics of complex failures.Through practical problem-solving, you will ensure Zipline’s aircraft continue to operate safely and reliably in the most demanding environments on Earth.

Your work will span the full operation lifecycle from initial product release and early life learning, through identifying and driving targeted reliability improvements, and ultimately end-of-life decisions. You will transform field data into actionable insights by identifying failure trends and quantifying risk. Your reporting will inform data-driven decisions in design, manufacturing, and operation decisions that improve fleet availability, reduce operating cost, and directly influence customer satisfaction.

What You’ll Do

• Identify, develop, and maintain metrics for how long products or systems function in the field and verification tests, using measures of time, cycles, or distance (life data) to predict failure.

• Select, develop, and maintain fleet stress and usage metrics using internal data infrastructure to monitor functional performance, predict failure, and recommend intervention.

• Develop and maintain fleet-reliability models that feed into cost and spares planning efforts.

• Create accessibility and visibility of these measures across the business in database tables, dashboards, and reports.

What You’ll Bring


Must have

• BS/MS in Mechanical, Electrical, Materials Science, or related field, with 5+ years of experience in reliability, maintenance, or service engineering.

• Proficiency in reliability statistics and modeling: (Weibull/survival analysis, DOE, FMEA, FTA, and reliability growth analysis).

• Skilled in data analysis and scripting tools to analyze large vast datasets and forecast outcomes (Python, Reliasoft, Minitab, JMP, or MATLAB).

Nice to have

• Strong communication and leadership skills with a track record of influencing design, manufacturing, and operational decisions across mechanical, electrical, and software disciplines.

• A proactive, systems-level mindset that drives issues to resolution and builds organizational reliability culture.

What Else You Need to Know

The starting cash range for this role is $150,000-$215,000. Please note that this is a target, starting cash range for a candidate who meets the minimum qualifications for this role. The final cash pay for this role will depend on a variety of factors, including a specific candidate's experience, qualifications, skills, working location, and projected impact.
