Senior QA Engineer - Autonomous Haulage Systems

Komatsu Mining Corp.; Mesa (AZ); On-site; USD 120,000 - 150,000; Full time

Job summary

Komatsu Mining Technology Solutions in the United States is seeking a Senior Software Quality Assurance Engineer for the Autonomous Haulage System (AHS). You will own end-to-end quality strategy across functional, performance, security, and failover testing in a distributed, real-time environment.

Based in Tucson or Phoenix, Arizona, you will mentor engineers, drive test automation, and partner with product and hardware teams to deliver robust automation within CI/CD and containerized test

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.
• 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 expertise with CI/CD, containerization, and infrastructure-as-code for on‑demand test environments.

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.
