With a diverse line of products supported by our advanced technologies, regional distribution channels, and a global service network, we tap into the power of data and technology to enhance safety and productivity while optimizing performance.

Modular Mining Systems is the global leader in mine management technology and a wholly owned subsidiary of Komatsu Ltd. Our innovative technology powers mine operations in every corner of the globe. The products we cultivate, the solutions we engineer, and the service we deliver set us apart in the mining technology industry. We’re more than a company, and we’re a community of passionate, creative professionals striving toward a shared vision: revolutionizing the way the mining industry operates. With a presence stretching from Johannesburg to Vancouver, Sydney to Lima, you are part of a global brand that supports creativity, fosters innovation, and encourages you to think big, share ideas and have impact.

Job Purpose

The Autonomous Haulage System (AHS) is a comprehensive fleet management system for mines. Autonomous trucks are centrally controlled through a wireless network that integrates on-board vehicle controllers, high precision global positioning, and obstacle avoidance systems. The AHS Product Development team is responsible for building innovative solutions to unique and challenging autonomous operation problems. Working with our partners around the world, you will help design and support the next generation of mine optimization technologies and build the future platforms that will drive the changes in the mining industry for generations.

As a Quality Assurance Engineer III – Autonomous Haulage System (AHS), you will engage with experienced cross-disciplinary team members to conceive and design innovative automation products. You will work closely with product management, hardware engineering, and operations teams. You must be responsive, flexible, and able to succeed in an open and collaborative peer environment.

Key Responsibilities

• Maintain deep understanding of AHS architecture, dependencies, and safety constraints; translate this knowledge into risk-based test plans and automated coverage.
• Partner with product and engineering teams to extract, refine, and document functional+nonfunctional requirements; ensure each requirement has measurable acceptance criteria and automated validation.
• Own the end-to-end quality strategy—including functional, performance, security, and cross functional initiatives—leveraging service virtualization, contract testing, and containerized environments to maximize parallel execution in CI/CD.
• Design, implement, and continuously enhance robust automation frameworks. Integrate tests seamlessly into CI/CD pipelines with infrastructure as code provisioning.
• Drive a shift left culture: embed test hooks at design time, manage test data versioning, and maintain high signal regression suites that execute on every merge.
• Lead execution of manual edge case and exploratory tests; automate everything else. Publish clear dashboards for pass/fail trends, defect escape rate, and MTTR; use metrics to guide continuous improvement.
• Facilitate blameless postmortems, identify systemic issues, and convert findings into preventative automated checks.
• Oversee compatibility matrices and deployment configurations, support field teams during installation, configuration, and on-site validation.
• Mentor engineers, champion coding standards for test development, and pilot new tools or methodologies that increase team productivity and product quality. Coordinate cross functional initiatives to mature quality practices enterprise wide.
• Be able to occasionally travel internationally.
