You will also own the Engineering Change Order process for your systems, ensuring that improvements move efficiently from concept to release as the product and fleet scale.

If you’re looking for a role that combines deep design expertise with hands-on engineering impact, this is it.

What you'll be driving

Ownership and Delivery

• 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.

Hands-on build and validation

• 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.

Cross-functional execution and scale

• Work closely with procurement and supply chain to create and manage BOMs, source components, and support suppliers during early builds and iteration phases.
• Drive and participate in rigorous design reviews, ensuring technical excellence and cross-functional alignment.
• Release hardware configurations for engineering and commercial use with accurate documentation, GD&T, and PLM data.

What are we looking for

• 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..
