Job description

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.

About the Role

Pronto is seeking an Embedded Firmware Engineer to join our growing team and help expand our autonomous haulage systems. You'll be working on cutting‑edge technology that's transforming the mining and heavy equipment industries, implementing robust firmware solutions for some of the most challenging environments on Earth. We are looking for someone who is comfortable with bare‑metal microcontroller firmware, debugging and identifying issues with novel hardware, and ground‑up implementation of firmware for circuits in a real‑world environment.

What you’ll do

• Read and interpret complex electrical schematics and understand the physical functionality of custom‑built PCBs
• Collaborate with electrical and software engineers to develop comprehensive specifications for new hardware
• Develop firmware for custom boards from the ground up based on schematic designs and functional requirements
• Extend and enhance existing firmware codebases to support new features and capabilities
• Examine, document, and develop interfaces for existing third‑party vehicle communications systems
• Implement firmware for drive‑by‑wire retrofit systems on new vehicle platforms
• Support field installations and troubleshoot hardware and firmware issues at customer sites

What we’re looking for

• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, or related field is required
• Strong experience with embedded systems and real‑time control applications
• Proficiency with common communication protocols (CAN, SPI, I2C, UART, Ethernet, etc.)
• Experience with at least one CAN protocol (e.g. J1939 , CanOpen) or LIN is a plus
• Deep understanding of electronics and their physical operation, capabilities, and limitations
• Hands‑on experience with electrical hardware implementation, testing, and validation from concept through production
• Exceptional debugging skills across software, firmware, and hardware domains
• Experience in interfacing with off‑highway vehicles (such as dozers or skid‑steers) or passenger cars is a great plus
• Ability to thrive in a fast‑paced, collaborative environment
• Willingness to travel occasionally for field deployments

Why join us

• Work on real, production‑deployed autonomy.
• Build technology that directly improves safety, efficiency, and productivity.
• Tackle complex challenges in demanding, real‑world environments.
• Be part of a fast‑moving team with high ownership and impact.
• See your work deployed and making a difference in the field.
• Collaborate closely with experienced engineers and industry operators.
