Job Purpose
At Komatsu, we're solving problems most software engineers will never encounter.
Every day, our software directs fleets of autonomous haul trucks weighing hundreds of tons as they move millions of tons of material across some of the largest and most remote mining operations on Earth.

We are looking for a Principal Software Engineer to help shape the future of FrontRunner, the world's leading autonomous haulage platform.
We are not looking for someone who has advised on large systems. We are looking for someone who has personally delivered them.
Travel Requirements
Up to 25%.

What You'll Do:

  • Strong software design and development experience, including Java and distributed systems.
  • Experience mentoring senior engineers and technical leaders.
  • Strong communication skills with technical and non-technical stakeholders.
  • Ensure the quality and reliability of software through rigorous testing and code reviews.
  • Develop and maintain technical documentation to support ongoing development and maintenance.
  • Manage project timelines and deliverables, ensuring projects are completed on time and within budget.
  • Foster a culture of continuous improvement and technical excellence within the team.

Desired Skills
  • Autonomous systems, robotics, or industrial automation.
  • Distributed control systems.
  • Real-time software systems.
  • Networking and distributed application debugging.
  • Experience working in operationally critical environments.
  • Bachelor's or Master's degree in Computer Science or equivalent experience.
