Senior QA / Test Automation Engineer

Sourceability is building a new Global Engineering Organization (GEO) to strengthen internal software delivery, improve production ownership, and build long-term engineering capability inside the company.

We are looking for a Senior QA / Test Automation Engineer to help build quality discipline and test automation capability inside GEO. This role will support business-critical software platforms by improving test coverage, regression testing, defect validation, release readiness, and automation practices across engineering teams.

This role is not limited to writing automated tests. The right candidate should be able to combine hands-on manual testing, exploratory testing, test automation, defect analysis, UAT support, and risk communication. At the current stage of GEO, some systems may have limited automated coverage, incomplete documentation, and legacy behavior that must be understood carefully before changes are released.

The Senior QA / Test Automation Engineer will work closely with Software Engineers, Product / Delivery Managers, Product Group Team Leads / Architects, DevOps, DBA, Infrastructure, and business stakeholders to reduce production risk and improve confidence in releases.

This role is hybrid working from our Singapore office.  

Insight on Your Impact:

In this role, you will:

• Design, develop, and maintain automated test coverage for web applications, APIs, integrations, mobile workflows, and internal business platforms.
• Execute manual, exploratory, functional, regression, integration, API, and release validation testing where automation does not yet exist or is not practical.
• Build and improve test automation frameworks, test scripts, reusable test utilities, and test data approaches.
• Define practical regression testing strategies for business-critical systems, including SourceCore, mobile applications, integrations, legacy applications, and other GEO-supported platforms.
• Partner with Product / Delivery Managers to understand acceptance criteria, business workflows, UAT expectations, and release scope.
• Partner with Product Group Team Leads / Architects and Software Engineers to understand technical design, risk areas, edge cases, and testability concerns.
• Participate in backlog refinement by identifying missing acceptance criteria, unclear requirements, test dependencies, and quality risks.
• Create and maintain test plans, test cases, test data, and validation checklists aligned with product requirements and business workflows.
• Identify, document, prioritize, and track defects clearly through agreed tools and processes, including Azure DevOps where applicable.
• Verify fixes, confirm regression impact, and help determine whether a release is ready for production.
• Integrate automated tests into CI/CD pipelines in partnership with DevOps and engineering teams.
• Analyze test failures, flaky tests, environmental issues, and data-related problems to help engineering teams distinguish product defects from test or environment problems.
• Support UAT by helping Product / Delivery Managers and business users prepare validation scenarios, review acceptance criteria, and reproduce reported issues.
• Communicate quality risks, test coverage gaps, defect trends, and release readiness concerns to engineering and product stakeholders.
• Contribute to post-release issue analysis and help convert production defects into regression coverage and process improvements.
• Mentor junior QA engineers and help establish practical QA standards, automation practices, and quality expectations across GEO.

Your Qualifications, Your Influence:

To be successful in this role, you should have:

• 5+ years of experience in software quality assurance, with strong hands-on experience in both manual testing and test automation.
• Proven experience building, maintaining, or extending test automation frameworks using tools such as Playwright, Cypress, Selenium, Appium, or equivalent.
• Strong understanding of functional, regression, integration, API, exploratory, smoke, performance, and release validation testing.
• Experience testing business-critical software systems where defects can directly affect operations, users, customers, or financial processes.
• Ability to read and write code in at least one programming language such as JavaScript / TypeScript, C#, Python, or Java.
• Experience with API testing tools and approaches such as Postman, REST Assured, Playwright API testing, or similar frameworks.
• Experience integrating automated tests into CI/CD pipelines using tools such as Azure DevOps, GitHub Actions, Jenkins, GitLab CI, or similar.
• Practical understanding of SQL and ability to validate data, investigate defects, prepare test data, and confirm backend behavior.
• Experience writing clear defects, test cases, test plans, acceptance criteria feedback, and quality risk summaries.
• Ability to work with incomplete requirements, legacy behavior, and complex business workflows without losing testing discipline.
• Strong analytical and troubleshooting skills with a methodical approach to reproducing, isolating, and documenting issues.
• Clear communication skills with the ability to explain quality risks, testing limits, defect impact, and release readiness to technical and non-technical stakeholders.
• Comfortable working in distributed teams across multiple locations and time zones.
• Strong ownership mindset, attention to detail, and practical judgment under delivery pressure.

Preferred Skills and Technical Familiarity:

The following experience will be helpful in this role:

• Experience testing .NET / SQL Server-backed enterprise applications.
• Experience testing internal platforms used by sales, purchasing, warehouse, finance, operations, customer service, or other business teams.
• Experience with mobile test automation for Android or iOS using Appium, Espresso, XCUITest, or similar tools.
• Experience testing warehouse applications, barcode scanning workflows, image capture workflows, or field / operations-facing mobile applications.
• Experience with performance and load testing tools such as k6, JMeter, Gatling, or similar.
• Experience with test data management, environment validation, release smoke testing, and regression suite design.
• Familiarity with accessibility testing, security testing concepts, or basic application vulnerability validation.
• Experience in electronic components, technology distribution, supply chain, logistics, manufacturing, e-commerce, or similar B2B environments.
• Exposure to AI-assisted testing tools or practical use of automation to improve test coverage and QA productivity.

Success in the First 90 Days:

Within the first 90 days, the Senior QA / Test Automation Engineer should be able to:

• Understand assigned systems, business workflows, release process, current test coverage, and major production quality risks.
• Establish working relationships with Software En
