Aeroelasticity Engineer

Mechanical Design Engineer

Zipline is the world's largest and most experienced autonomous delivery service, founded to serve all humans equally by ensuring access to 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 including blood, vaccines, medical supplies, food, and commercial products.

Our customers include healthcare systems, governments, retailers, and global brands who rely on us to save lives, reduce emissions, increase economic opportunity, and provide new logistics services at scale.

Our technology goes beyond drones. We deploy integrated logistics infrastructure that strengthens supply chains, reduces congestion, and enables instant delivery, transforming how essential goods reach people everywhere. 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.

This posting represents multiple Mechanical Design Engineering opportunities across our Engineering organization. We're hiring across several teams (Avionics, Structures & Mechanisms, Powertrain & Battery, Ground Systems, and more) and across multiple seniority levels. Candidates who apply will be considered for all open roles that align with their background. During your first conversation, we will work with you to identify the best team and level match, based on your experience and interests.

Does working on large integrated electro-mechanical systems from conception through fully scaled production and world-wide deployment excite you? At Zipline, our work is intended for the field. Patients are counting on it today and there is no time for aiming low or coming up short. If leveraging your talent to drive creating elegantly engineered solutions excites you, read on.

We're looking for driven, proactive Mechanical Design Engineers to join various hardware teams across the organization. Mechanical Design engineers are responsible for coming up with novel designs that not only meet their intended function, but are also robust enough to handle the severe environments our aircraft are exposed to on an everyday basis. This person will be the complete owner for their hardware, hands-on in moving projects forward through each phase of the product design process (Design, Build, Test, Repeat, Scale) to produce high-impact products and manage projects on short timelines.

Additionally, design engineers are responsible for overseeing their designs into production, ensuring designs meet their design requirements, are manufacturable, inspectable, and can be built  Mechanical Engineers know their hardware inside and out and work seamlessly with Software, Integration, Production, Suppliers, and Test to make sure their hardware is functioning effectively as a part of the whole system.

Must Have Experience / Skill Sets:

• 3-12+ years of full time working experience, at a business, designing electromechanical and structural assemblies
• Proven track record of complex subassemblies or full systems over at least two product programs
• Demonstrated CAD fluency for system-level ownership (3D/2D of 20–30 parts simultaneously)
• Experience working with suppliers and seeking DFM feedback
• Experience working on structural components and mechanisms, identifying worst-case loads, creating quick test setups
• Demonstrated core competencies: GD&T, FEA (multi-body structural and thermal), design for assembly and field ops
• Prototyping experience and quick iterations on owned projects
• Ability to bound problems with hand calcs (beam, buckling, bolted joints, etc.)
• Knowledge of appropriate safety margins for human safety critical applications
• Excellent written, verbal, and visual communication skills
