Provides advanced technical leadership in the design, development, and execution of application quality engineering and performance testing strategies for , Caterpillar’s global eCommerce platform.

Responsible for ensuring that complex, distributed software systems meet defined functional requirements, performance expectations, and production readiness standards. Operates at a system level to influence software design, validate application behavior, and ensure performance integrity across the full software development lifecycle.

This role requires deep, hands‑on expertise in functional test automation and performance engineering tools, combined with the ability to guide engineering teams and shape practices that improve application stability, scalability, and customer experience.

• Designs and leads execution of functional testing strategies across UI, API, and integration layers using modern automation tools (e.g., Playwright).
• Validates behavior of complex, multi‑tier, distributed applications, ensuring correct transaction flow across frontend, services, and backend systems.
• Defines and enforces test strategies, coverage models, and release readiness criteria.
• Leads end‑to‑end validation across testing phases including in‑sprint, regression, system integration (SIT), and E2E.
• Ensures software products meet defined functional requirements, customer journeys, and business workflows.

• Leads design and execution of performance testing strategies using tools such as k6, JMeter, and Artillery.
• Designs and executes load, stress, endurance, and scalability testing aligned to production conditions.
• Defines and enforces non‑functional requirements (NFRs) and performance service level objectives.
• Conducts performance diagnostics using logs, metrics, API traces, and observability data to identify system bottlenecks.
• Drives root‑cause analysis and resolution of performance issues across application and infrastructure layers.
• Ensures performance validation reflects real customer usage patterns and end‑to‑end system behavior.

• Partners with development teams to improve application design, performance, and testability.
• Reviews and influences technical solutions and architecture decisions to ensure alignment with quality and performance standards.
• Provides technical guidance on automation frameworks, testing tools, and performance engineering approaches.
• Supports definition of technical requirements and acceptance criteria, including functional and non‑functional considerations.

• Applies structured methodologies to support delivery and validation across the SDLC.
• Drives adoption of shift‑left testing practices, enabling earlier identification of defects and performance risks.
• Collaborates with Product, Development, and SRE to align on release scope, quality expectations, and delivery timelines.
• Ensures consistent execution of processes across development, testing, and release phases.

• Defines and leads implementation of automated testing strategies across:
  • Functional testing (Playwright)
  • Performance testing (k6, JMeter,…
