Komatsu; Phoenix (AZ); On-site; USD 120,000 - 160,000; Full time

Job summary

Komatsu is seeking a Quality Assurance Engineer III for the Autonomous Haulage System (AHS) to join our global Product Development team. You will design and execute robust test strategies, build automation, and partner with product, hardware, and operations to ensure high-quality autonomous mining software and systems.

You will work with modern automation languages, CI/CD pipelines, and containerized environments, and you may travel internationally.

Qualifications

• Bachelor's degree in computer science, software/systems engineering, or related discipline (Master's a plus).
• 6+ years combined experience in software/systems testing, with 4+ years focused on building and scaling test automation.
• Ability to take a project from scoping requirements to production operations
• Leadership defining comprehensive test strategies for complex, distributed or realtime systems.
• Proficient in at least one modern programming language used for automation (Java, Python, or C#); strong REST/gRPC API and UI automation experience.
• Hands-on with CI/CD, containerization, and infrastructure-as-code for on-demand test environments.
• Ability to mentor, influence, and uplevel QA and development teams.
• Excellent analytical, documentation, and cross-functional communication skills.
• Ability to travel for up to 10% of the time

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 fail over testing—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.
