About this role

Who we are

Pronto AI is a global leader in commercializing autonomous vehicle (AV) technology, deploying Autonomous Haulage Systems (AHS) that automate operations in mines, quarries, and construction sites worldwide. While much of the industry remains in R&D, we deliver real, production-ready autonomy that is already operating in the field.

We are on a mission to make mining operations safer, smarter, and more efficient through cutting-edge technology, and we are building toward becoming the world’s first profitable AV technology company.

What you’ll do

  • We’re seeking exceptional mechanical engineers to help develop the Pronto Autonomous Haulage System.

  • You will be responsible for owning designs through prototype and assembly as well as installing systems onto vehicles as large as 100+ ton haul trucks, while developing documentation to scale installations. All aspects of the role will be very hands-on and will involve fieldwork.

  • Projects could include sensor design and placement, drive-by-wire system hardware design, and system architecture planning. Additionally, projects may be R&D oriented for new vehicle platforms or iterating on existing designs. Some procurement and vendor management responsibilities will likely be required.

  • Apply mechanical engineering principles for the development and integration of drive-by-wire hardware including actuators and sensors

  • Travel to customer sites for development and initial installation of hardware systems (up to 30%)

  • Develop bespoke solutions to customer specific problems

  • Refine current hardware kits for efficient scaling

  • Develop vehicle hardware kits for new platforms

  • Develop 2D and 3D CAD models of mechanical and electro-mechanical components and assemblies

  • Create and maintain documentation of design solutions including reports, engineering drawings, Bills of Material, and installation instructions

  • Develop testing and validation procedures for electromechanical systems

  • Build prototypes using various rapid prototyping technologies (e.g. 3D print, laser cut)

  • Source components and manage vendors

  • Work on system level design with a cross-functional team to develop mechanical and electro-mechanical solutions

  • What we’re looking for

  • Bachelor's degree in Mechanical Engineering, Mechatronics, or a closely related field is required.

  • Minimum 2+ years of non-internship professional Mechanical Design Engineering experience.

  • Automotive or heavy equipment industry experience strongly preferred

  • Familiarity with robotic systems is strongly preferred

  • Experience/ expertise with 3D CAD tools

  • Hands on experience building mechanical and/or electrical systems; machine shop and/or fabrication experience preferred

  • Experience designing for CNC machine, sheet metal fab, and 3D print

  • Experience with hydraulic systems is a plus

  • Ability to resolve issues during design, development and execution of mechanical engineering activi
