• AI-Driven Testing & Evaluation: Champion the use of AI across the test lifecycle, including AI-assisted test case generation, automated/self-healing test maintenance, and AI-driven analysis of test results and failures, while evaluating, benchmarking, and continuously improving the accuracy and reliability of AI agents used in testing and quality workflows

• Deployment Ownership: Take ownership of deploying product services to production, ensuring appropriate quality gates and rollback plans are in place

• Cross-Functional Collaboration: Partner closely with Engineering, Product, and Design to align test coverage and release readiness with product and business priorities

• Code Review: Conduct thorough code reviews to maintain code quality, identify opportunities for improvement, and share constructive feedback with team members

• Cloud Expertise: Leverage AWS services, including but not limited to AWS Lambda, API Gateway, EC2, S3, and RDS, to architect and optimize cloud-based solutions

• Problem Solving: Troubleshoot and resolve complex technical issues, identifying root causes and implementing effective solutions

Requirements & Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related discipline

• 5+ years of experience in Software Development Engineering in Test roles, with a strong track record in building, scaling, and maintaining functional, API, and UI test automation frameworks, including experience leading or mentoring engineers

• Hands-on experience applying AI/LLMs across the test lifecycle - including AI-assisted test generation, automated/self-healing test maintenance, and AI-driven analysis of test results and failures - along with the analytical skills to evaluate and improve the accuracy and reliability of AI agents

• Experience standing up and maintaining test infrastructure and CI/CD pipelines in containerized environments (Docker/Kubernetes), and owning deployment/release processes for production services

• Strong programming skills in one or more of Python, Java, JavaScript/TypeScript, or Go

• Excellent leadership, communication, and stakeholder management skills
