What this job asks for AI summary
This role leads quality engineering and performance testing for a large-scale global eCommerce platform, covering functional test automation across UI, API, and integration layers as well as load and stress testing. Day-to-day work involves designing test strategies, integrating automated tests into CI/CD pipelines, diagnosing performance bottlenecks, and collaborating with development and product teams to shape architecture and release readiness. It suits an experienced engineer with hands-on expertise in tools such as Playwright, k6, and JMeter working in distributed, cloud-based environments.

Why we read it this way (7)
The job title carries no seniority level word, but the scope — leading performance and quality engineering strategy for a global eCommerce platform, mentoring engineers, influencing architecture — clearly supports Senior.
Playwright is listed as the primary UI automation tool with 'or similar modern UI automation framework' as a qualifier; Selenium, Cypress, and WebdriverIO are captured as alternatives. k6, JMeter, and Artillery are all named together as performance tools; they are treated as interchangeable alternatives for the same performance-testing requirement rather than distinct separate gates, since the JD uses 'and/or' framing.
The degree requirement states 'Bachelor's degree … or equivalent experience,' so no formal degree is hard-gated.
No overall years-of-experience number is stated; the JD uses qualitative language ('extensive experience') rather than a specific figure.
The posting location is not explicitly stated in the body, but Caterpillar's Cat Digital headquarters is in the Peoria, IL metro; the role may also be based in Irving, TX or another Cat Digital hub — location is ambiguous.
CI/CD integration and observability tools (Grafana, Datadog, OpenSearch), AWS, and HCL Commerce all appear under the 'Preferred Qualifications' section and are marked accordingly.
Artillery appears as a named alternative alongside k6 and JMeter in the required performance-testing block; it is captured in the alternatives arrays rather than as a standalone skill to avoid triple-counting the same requirement.
