WE ARE LOOKING FOR SOFTWARE TEST LEAD IN SINGAPORE TO JOIN US!

As a Software Test Lead/Architect, you shape the testing strategy and architecture for high-precision metrology and configuration-management software.

Your job will comprise:

• Test Strategy & Planning: Develop and maintain test strategies, plans, specifications and validation approaches. Identify coverage gaps, risks and required test assets early in development, and align testing effort with requirements and product priorities.

• System & Integration Testing: Integrate software components from multiple development teams, verify interfaces and validate end-to-end workflows, from recipe configuration through measurement to processed results.

• Test Bench & Machine-State Replication: Capture machine snapshots, including measurement data, profiles, recipes and software versions, and reproduce these states on virtual test benches or physical machines when required.

• Release & Feature Acceptance: Translate requirements into structured manual and automated test cases. Perform smoke, regression, upgrade and feature-acceptance testing, and provide evidence-based recommendations on whether features are ready for release.

• Test Automation: Develop and maintain test automation and scripts using C#/.NET and Python, including integration, smoke, regression, UI and feature tests where appropriate. Use simulation, mocking and Hardware-in-the-Loop approaches when suitable.

• Defect Investigation: Analyze logs and test data, reproduce field issues, isolate failures to the relevant component, and document defects with clear evidence to support root-cause analysis and resolution.

• Testability & Continuous Improvement: Collaborate with software, systems and hardware architects to improve testability by design. Contribute to sprint planning, backlog refinement and Definition of Done discussions, and continuously improve test coverage and efficiency.

• Test Management & Collaboration: Maintain test cases and results in test-management tools such as Jira with Xray or Zephyr. Coordinate test scope, test-bench availability and defect resolution with customer engineers, test leads and developers across regions.

Required Qualifications & Skills:

• At least 7 years of hands-on software testing experience, test strategy or architecture, including system or integration testing of complex equipment software or embedded systems.

• Strong understanding of complex products and the ability to map requirements to tests, assess coverage and identify quality risks.

• Practical experience with C#/.NET and Python for test automation, scripting, simulation or test tooling.

• Experience with test frameworks such as NUnit, SpecFlow or pytest, and version control using Git.

• Experience with simulators, virtual test benches or Hardware-in-the-Loop environments, as well as installing, configuring and upgrading software releases.

• Ability to investigate integration issues using logs and data, reproduce failures and perform root-cause analysis.

• Good analytical, communication and collaboration skills, including working with distributed, cross-functional teams.

Preferred Qualifications:

• Experience in semiconductor equipment, metrology, complex machine-control systems, industrial automation, robotics or mechatronics software.

• Familiarity with SECS/GEM or factory-automation interfaces.

• Experience with desktop UI test automation for Windows applications, such as FlaUI.

• Knowledge of Windows and Linux environments, virtual machines and networking basics.

• Familiarity with structured testing practices such as ISTQB, and test-management tools such as Jira Xray or Zephyr.

Soft skills:

• Strong logical thinking, proactive mindset, and a high sense of ownership, responsibility, and commitment.

• Comfortable working in a fast-paced, dynamic environment with changing priorities and technologies.

• Excellent teamwork and communication skills, with the ability to work directly with international clients in English.

• Passionate about continuous learning and eager to grow in equipment, semiconductor, and other high-tech engineering domains.

• Open-minded and improvement-driven, with a willingness to adopt modern engineering and testing practices.
