• Build and enhance reusable test automation frameworks using modern technologies and integrate automated testing into Continuous Integration and Continuous Delivery (CI/CD) pipelines.

• Develop test strategies, plans, scenarios, and traceability documentation aligned with business requirements and technical specifications.

• Execute functional, regression, integration, end-to-end, and exploratory testing to identify defects and ensure application stability.

• Investigate software defects, analyze system logs, identify root causes, and collaborate with development teams to implement effective solutions.

• Validate essential digital banking functionalities, including authentication, multi-factor authentication (MFA), account balances, fund transfers, bill payments, Interac e-Transfer, mobile cheque deposits, and account servicing.

• Test commercial banking workflows, including delegated access, user entitlements, approval processes, and business payments.

• Verify integrations between digital banking platforms, core banking systems, payment services, lending applications, and Customer Relationship Management (CRM) solutions.

• Support data migration testing, data reconciliation, and regression testing during banking platform replacements and modernization initiatives.

• Participate in System Integration Testing (SIT), User Acceptance Testing (UAT), release readiness activities, and production validation.

• Collaborate with client business teams to ensure test scenarios accurately reflect real banking operations and customer needs.

• Contribute to Agile delivery activities, including sprint planning, backlog refinement, acceptance criteria definition, and continuous quality improvement.

• Integrate quality engineering practices into software development workflows and establish automated quality gates, including controls for AI-assisted software development.

• Support performance, security, and accessibility testing in collaboration with specialized teams, ensuring compliance with relevant standards.

• Produce clear quality metrics, defect reports, test coverage assessments, and release-readiness recommendations.

• Continuously identify opportunities to reduce manual regression testing, improve automation reliability, and strengthen confidence in production releases.

• At least 5 years of professional experience in software testing, Quality Assurance (QA), or quality engineering, including a minimum of 3 years of hands-on test automation development.

• Previous experience testing financial services, banking, credit union, or other transaction-intensive applications.

• Strong proficiency in at least one modern test automation framework, such as Playwright, Cypress, Selenium, or Appium.

• Programming or scripting experience with TypeScript, JavaScript, Java, C#, or Python.

• Solid API testing experience using Postman, REST Assured, or equivalent tools, with a strong understanding of REST APIs, authentication, authorization, and system integrations.

• Experience with SQL, database validation, data integrity testing, and troubleshooting complex integration issues.

• Familiarity with CI/CD pipelines and development tools such as Azure DevOps, GitHub Actions, or Jenkins.

• Strong understanding of Software Development Life Cycle (SDLC), Agile methodologies, defect management, risk-based testing, and software quality engineering principles.

• Excellent analytical and problem-solving abilities, with strong attention to detail and the ability to investigate complex technical issues.

• Strong communication and collaboration skills, including the ability to work effectively with distributed engineering teams and communicate directly with client stakeholders.

• Highly desirable experience includes working with Canadian credit unions or digital banking transformation initiatives.

• Experience testing digital banking platforms such as VeriPark, Backbase, Central 1 Forge/MemberDirect, Intellect Design, Temenos, Lumin, eBankIT, or Finastra.

• Previous experience with core banking system integrations, particularly Fiserv DNA or CGI RFS360.

• Knowledge of Canadian payment capabilities, including Interac e-Transfer, bill payments, and payment processing workflows.

• Familiarity with mortgage lending, loan origination, commercial banking, and CRM processes.

• Experience working with Microsoft Dynamics 365, Microsoft Azure, and .NET-based enterprise environments.

• Hands-on experience testing mobile applications across iOS and Android platforms.

• Knowledge of performance testing tools such as JMeter, k6, or equivalent solutions.

• Experience conducting accessibility testing and ensuring compliance with WCAG standards, particularly WCAG AA and AODA requirements.

• Exposure to AI-generated code testing or the implementation of automated quality controls in AI-assisted development environments.

• Experience supporting banking platform migrations, cutover activities, and post-launch production hypercare.
