Software Engineer - Test Automation

Job Title

Software Engineer - Test Automation

Role Summary

Design, build, and scale code-driven test automation for UI, REST/API, and system-level validation of software integrated with hardware for semiconductor products. Work on a cross-functional engineering team to implement maintainable automation frameworks, automated test execution, data extraction, and reporting pipelines.

This is a hands-on engineering role focused on delivering reliable automated validation and actionable quality signals for complex hardware-software systems.

Experience Level

Senior-level. Posting indicates approximately 6+ years of hands-on experience in test automation; alternative minimums specified by degree level in Education Requirements.

Responsibilities

Primary responsibilities include development and ownership of automated test suites across UI, API, and end-to-end system scenarios.

• Develop and maintain automated UI tests for Windows desktop applications; design reusable UI components and object wrappers for maintainability and scalability.
• Create and maintain automated tests for REST interfaces and service integrations; improve API test coverage and pipeline signal quality (notifications, dashboards, regression enablement).
• Own end-to-end automated validation for features where software interacts with hardware; balance automation and targeted manual testing for hardware-integrated scenarios.
• Collaborate with engineering, algorithms, systems, hardware, applications, and manufacturing teams to plan and execute test strategies aligned to releases.
• Build automation infrastructure for complex bench/tool environments and database-backed test systems; integrate test execution, data extraction, and reporting into repeatable pipelines.
• Lead test planning and strategy execution; analyze failures (including use of intelligent algorithms) and present root-cause findings via dashboards and reporting tools.

Requirements

Must-have technical skills and experience; degree requirements summarized separately under Education Requirements.

• 6+ years of hands-on experience in test automation (as indicated in the posting) or equivalent practical experience in software test engineering.
• Proficiency in one or more: C++, C#, Java, Python, or R.
• Experience with UI automation frameworks and building maintainable automation components.
• Experience with REST/API testing and automation frameworks.
• Strong SQL and NoSQL data handling skills, and experience with data preprocessing.
• Solid understanding of algorithms, data structures, software design, computer architecture, and API design.
• Familiarity with profiling, scaling, and tuning relational and non-relational databases (examples: SQL Server, Redis, MongoDB).
• Experience working in complex, multi-functional hardware-software environments and integrating automation with instrumentation.
• Strong written and verbal communication skills; self-starter who adapts to evolving requirements.

Nice-to-have:

• Experience with machine learning frameworks (TensorFlow, PyTorch, Keras) and applying intelligent algorithms to testing and failure analysis.
• Knowledge of Kafka, Kubernetes, Hadoop, BigQuery, MySQL, and other open-source data technologies.
• Experience with CI tools (Jenkins), API tools (Postman, RestSharp), and reporting tools (Power BI).

Education Requirements

Minimum qualifications listed by degree: Doctorate (PhD) with 0 years related experience; Master’s degree with ~3 years related experience; Bachelor’s degree with ~5 years related experience. (The posting specifies degree-based minimums for experience; fields of study are not specified.)
