Senior Mechanical Engineer (Long Range Platform)

Join Zipline, a leading company in autonomous delivery technology. As a Senior Mechanical Engineer, you will be responsible for designing, validating, and delivering 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. This role requires hands-on prototyping and test experience, as well as a strong bias for taking end-to-end ownership.

About Zipline

We value diversity at Zipline and welcome applications from those who are traditionally underrepresented in tech. If you like the sound of this position but are not sure if you are the perfect fit, please apply!

Responsibilities

• 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 dessins de fabrication et diriger les campagnes de test.
• 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

Requirements

• 4+ years industry experience designing electromechanical and structural assemblies; demonstrable ownership of complex subassemblies through full product cycles (design → qualification → production ramp)
• 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
• 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
• Direct supplier engagement experience: negotiating DFM changes, resolving quality issues, and translating supplier capabilities into producible designs

Pay

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
