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 You and The Role You are an owner-oriented Mechanical Engineer joining Zipline's Long Range Platform team to design, validate, and deliver critical airframe and electromechanical hardware used in long-distance autonomous delivery aircraft. This role sits at the intersection of field logistics, fleet operations, and mass production: your work will reduce aircraft weight, increase structural and mechanism reliability in harsh field conditions, and enable higher sortie rates for customers who depend on predictable, high-uptime deliveries. You will operate with end-to-end hardware responsibility—from requirement definition and architecture trade-offs through prototype validation, supplier integration, production ramp, and in-field sustainment—and you will make decisions that directly affect fleet availability, safety margins, and cost-per-delivery. What You'll Do - Own specific Long Range mechanical subsystems (e.g., wing/fuselage primary structure, deployable delivery mechanism, landing gear and attach fittings, or integrated payload-mount assemblies) and be the primary technical lead from concept to sustained production. - Translate operational and fleet requirements into quantitative mechanical performance targets and design architectures. - Produce and iterate detailed CAD models, tolerance stacks, GD&T, and manufacturing drawings enabling supplier quotes, DFx reviews, and inspection plans for volume production. - Run first-principles analysis and engineering simulation (FEA, buckling, fatigue, jointed-assembly loads) and validate with bench tests and flight-representative test rigs. - Prototype rapidly, lead hands-on build-test-iterate campaigns, and produce test plans tied to release criteria and field reliability goals. - Define and own verification matrices, failure modes and corrective actions through qualification and production ramp. - Partner with Electrical, Software, Integration/Test, Manufacturing Engineering, Supply Chain, and Operations teams to resolve cross-functional tradeoffs and production issues. - Support field deployments and production startups as required. What You'll Bring - 4+ years industry experience designing electromechanical and structural assemblies. - Demonstrated ownership of complex subassemblies through full product cycles. - Deep CAD fluency and rigorous GD&T skills. - Experience producing manufacturing-ready drawings and inspection criteria. - Proven track record applying FEA, hand calculations, tolerance analysis, and test correlation. - Hands-on prototyping and test experience. - Direct supplier engagement experience. - Experience with structural components, mechanisms, fastener systems, composites, or metallic airframe-scale assemblies. - Willingness and ability to travel as needed. - Strong end-to-end ownership mindset. Location & Logistics This role is based in the listed Long Range engineering location (on-site or hybrid as specified by the team). Expect regular on-site collaboration during critical phases and periodic travel to supplier/manufacturing sites and field depots. Nice-to-have - Aerospace or automotive validation experience. - Composites design experience. - High-efficiency electric powertrain exposure. - NX proficiency. - Experience scaling prototypes to injection molding, stamping, or extrusion processes. What Else You Need To Know Zipline is an equal opportunity employer and prohibits discrimination and harassment of any type. We value diversity and welcome applications from candidates who may not meet every qualification listed.
