Senior Mechanical Engineer

Join Zipline, a leader in autonomous delivery technology, as a Senior Mechanical Engineer. In this role, you will design, validate, and deliver critical airframe and electromechanical hardware for long-distance autonomous delivery aircraft. You will have end-to-end hardware responsibility, from requirement definition to production ramp and in-field sustainment. You will also partner with various teams to resolve cross-functional tradeoffs and production issues.

• Assumer la responsabilité de la conception, de la validation et de la livraison de sous-systèmes mécaniques spécifiques pour les aéronefs autonomes de livraison à longue distance.
• Traduire les exigences opérationnelles et de flotte en cibles de performance mécanique quantitatives et en architectures de conception.
• Produire et itérer des modèles CAD détaillés, des analyses de tolérance, des GD&T et des dessins de fabrication pour la production en volume.
• 4+ years industry experience designing electromechanical and structural assemblies; demonstrable ownership of complex subassemblies through full product cycles (design → qualification → production ramp)
• Direct supplier engagement experience: negotiating DFM changes, resolving quality issues, and translating supplier capabilities into producible designs
• Deep CAD fluency (managing 20–30 part subassemblies and top-level integration), rigorous GD&T skills, and experience producing manufacturing-ready drawings and inspection criteria
• Willingness and ability to travel to suppliers, production sites, and field depots on an as-needed basis (periodic domestic and occasional international travel)
• Strong bias for taking end-to-end ownership: you will stay with issues until verified fixes are in production and fielded
• Hands-on prototyping and test experience: you build fixtures, run validation campaigns, and close design loops from test data to production intent
• Experience with structural components, mechanisms, fastener systems, composites or metallic airframe-scale assemblies, and designing for serviceability in field conditions
• Proven track record applying FEA, hand calculations (beam, buckling, bolted joints), tolerance analysis, and test correlation to establish safety and reliability margins for flight or field-critical hardware
• Aerospace or automotive validation experience, composites design, high-efficiency electric powertrain exposure, NX proficiency, and prior experience scaling prototypes to injection molding, stamping, or extrusion processes
