About The Position

Wing is seeking a Senior Mechanical Engineer for its Ground Infrastructure Product Development team. This onsite role is based in Palo Alto, California, and focuses on scaling ground infrastructure to support changing operations and a diversified fleet of delivery aircraft. The engineer will apply broad mechanical design, prototyping, and analysis skills to take products from concept through design and manufacturing, solving complex problems with simple solutions in a fast-moving, adaptive environment. The role involves designing mechanical and electromechanical ground systems, including automated package loading, charging, and storage infrastructure. The engineer will develop detailed CAD models and manufacturing documentation, build and test prototypes, conduct structural and thermal analysis, and create modular systems suitable for deployment across diverse climates. The position also includes cross-functional and supplier collaboration, technical project leadership, and mentorship of junior engineers. Travel of up to 25% domestically and internationally is required.

Requirements

At least 8 years of professional hardware engineering experience designing, validating, and commercializing electromechanical systems, mechanisms, automated enclosures, or robotics.
Bachelor's or master's degree in Mechanical Engineering, or equivalent practical experience.
High proficiency in 3D CAD, top-level assembly integration, standard GD&T application, tolerance stack-up analysis, and production of manufacturing-ready drawing packages.
Ability to use hand calculations and FEA to establish safety and reliability margins for field-critical hardware.
Strong foundation in DFM/DFA for metals, plastics, and sealed outdoor enclosures suitable for harsh environments.
Experience designing test fixtures, validating hardware, analyzing field failures, and closing design loops.
Experience guiding contract manufacturers and JDMs, negotiating DFM changes, and resolving supplier quality and yield issues.
Strong communication and cross-functional collaboration skills to translate operational requirements into technical specifications and lead complex projects.
Willingness and ability to travel up to 25% domestically and internationally.

Nice To Haves

Proficiency in SolidWorks is preferred.

Responsibilities

Design mechanical and electromechanical assemblies for automated package loading, charging, storage, and other ground infrastructure.
Create and iterate 3D CAD models, tolerance stacks, GD&T, and manufacturing drawings for supplier quotes, DFM reviews, and incoming inspection criteria.
Design, build, and test quick-turn prototypes and validation fixtures for automated loading and charging concepts, and define release metrics.
Perform hand calculations and FEA structural and thermal analyses on critical assemblies.
Develop modular, standardized ground site systems that can be scaled and deployed cost-effectively across diverse geographic climates.
Partner with electrical, software, and operations teams to integrate hardware.
Collaborate with JDM and CM partners and external organizations and teams.
Work with manufacturing partners to ensure parts are designed for mass production.
Lead projects from initial concept through completion as a technical lead.
Provide guidance and mentorship to junior engineers.
