Senior Mechanical Engineer

About the role

As a Senior Mechanical Engineer, you will be a technical owner of mechanical systems that are designed, built, installed, and validated on real vehicles and remote drive station platforms used in live operations. You will shape next-generation hardware from clean-sheet design through on-vehicle validation, with direct responsibility for turning ideas into robust, production-ready components.

What you'll do

• Act as the technical owner of mechanical components: concept freeze through vehicle-level validation and release
• Lead hardware change initiatives end-to-end, from change request initiation through ECO closure and release
• Make design trade-offs independently while aligning stakeholders across engineering, testing, and operations
• Design new mechanical parts and assemblies in CAD, with a strong focus on manufacturability, durability, and integration into complex systems
• Coordinate or fabricate first prototypes, perform hands-on vehicle-level installation, and execute functional and environmental testing
• Partner with test and validation teams to define, execute, and iterate on validation plans based on real-world results
• Work closely with procurement and supply chain to create and manage BOMs, source components, and support suppliers during early builds and iteration phases
• Release hardware configurations for engineering and commercial use with accurate documentation, GD&T, and PLM data

What you'll need

• Bachelor's or Master's degree in Mechanical Engineering or a related field
• Several years experience in Mechanical Design, owning mechanical systems end to end, from concept through on-vehicle or system-level validation
• Deep expertise in CAD-based component and assembly design, including production-grade documentation
• Strong fundamentals in mechanical design, materials, and manufacturing processes
• Hands-on experience building, installing, and testing real hardware such as vehicles, robots, or complex machinery
• Experience working with PLM systems, GD&T, and formal release processes
• Comfortable operating with high autonomy in a fast-paced, cross-functional engineering environment
