• Build automation tools and internal services that improve QA and developer productivity.
• Use AI-enabled tools to streamline QA processes, reduce repetitive work, and improve test analysis, documentation, and workflow efficiency.
• Partner with engineering teams early to improve testability, risk coverage, and release confidence.
• Apply sound judgment when selecting test types and automation targets.
• Accurately identify edge cases, security concerns, performance risks, and failure modes.
• Lead complex projects from planning through delivery and serve as a subject matter expert for core testing platforms.
• Conduct code reviews, contribute to technical decisions, and uphold automation and coding standards.
• Mentor engineers to upskill the team, strengthen capability, and promote knowledge sharing.
• Apply strong sprint-process knowledge to support current priorities and long-term team goals.

Requirements

• Strong understanding of Continuous Integration (CI) and Continuous Delivery (CD) pipelines and integrating test automation within them.
• In-depth knowledge of test design, development, and execution, with the ability to implement best practices in test automation.
• Troubleshooting and problem-solving skills, with the ability to debug complex issues in both production and test environments.
• Familiarity with version control systems (e.g., Git) and containerization technologies (e.g., Docker) for test environments.
• Experience working in agile environments, collaborating closely with stakeholders to ensure stable releases
• Proven experience mentoring team members and upskilling engineers.
