To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale—faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.
Group/Division
The Semiconductor Products and Customers (Semi PC) business unit designs, builds and sells KLA’s product portfolio to help chip manufacturers meet high-quality standards for technologies like AI, data centers, automotive and electronic devices. Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics. KLA's Central Engineering organization is made up of nine Centers of Excellence (CoEs) spanning disciplines like automation, motion control, sensors, platform design, and packaging. Each CoE contributes not only technical deliverables but also deep expertise, best practices, and advanced tools that elevate both what we build—and how we build it.
What You'll Do
In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.
KLA is seeking a highly skilled Software Engineer in Test Automation with 6+ years of hands-on experience to design, build, and scale code-driven automation across three key areas: UI automation, REST/API automation, and System-level automation for software + hardware-integrated semiconductor products.
This role is ideal for a hands-on engineer with strong software development skills who can create maintainable automation frameworks, implement reliable automated tests, and deliver actionable quality signals by integrating test execution, data extraction, and reporting into repeatable pipelines.
Responsibilities include, but not limited to:
UI Automation
Develop and maintain automated UI test suites for Windows desktop applications using existing UI automation approaches and improve stability/maintainability of UI automation assets.
Design reusable UI automation components (object repositories/wrappers) to simplify maintenance and enable scalable UI test development.
API Automation
Create and maintain automated tests for REST interfaces and service integrations; apply API testing tools and automation frameworks where appropriate
Support/extend API test coverage initiatives and improve pipeline signal quality (notifications, dashboards, and regression enablement).
System & Hardware-Integrated Automation (End-to-End Product Validation)
Own end-to-end automated validation for key features, including system workflows where software interacts with hardware/instrumentation; balance automation with targeted manual testing as needed for hardware-integrated scenarios.
Collaborate with multi-functional team members across engineering, algorithms, systems, hardware, applications, and manufacturing to plan and execute test strategy aligned to releases.
Build automation and infrastructure that supports complex environments (bench/tool), including scenarios that are hardware-related and require focused validation.
Lead test planning, test strategy execution, and collaborate with team members across engineering, algorithms, systems, hardware, marketing, applications, and manufacturing teams.
Build systems that involve databases and our in-house automated testing framework.
Use intelligent algorithms, e.g. LLM, and business logic to find the root cause of software failures. Present them in an actionable manner through Power BI, dashboards, and other reporting and graphing tools.
