Job summary

Komatsu is seeking a Quality Assurance Engineer III for the Autonomous Haulage System (AHS) to design and implement robust automation across functional, performance, security, and failover testing. You will collaborate with product management, hardware engineering, and field teams to translate requirements into automated validation and measurable acceptance criteria.

Based in Arizona (Mesa/Phoenix/Tucson area), this onsite role demands strong leadership, hands-on automation, and the ability to

Qualifications

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 (Java, Python, or C#) with 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 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 dashboards for pass/fail trends, defect escape rate, and MTTR; use metrics to drive 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 and on-site validation.
Mentor engineers, champion coding standards for test development, and pilot new tools or methodologies to increase productivity and quality.
Be able to occasionally travel internationally.
