About the Team:

The Senior Staff Test Engineer will lead and elevate our automation engineering practice by architecting scalable, AI-powered test frameworks that accelerate software delivery across our quality engineering organization. This role will directly impact the reliability and speed of our product releases by driving a culture of quality engineering, mentoring a team of automation engineers, and embedding intelligent testing solutions — including custom AI agents and our CI/CD pipelines. Over the next 6–12 months, this role is expected to: (1) establish a standardized automation framework adopted across all quality engineering teams, (2) reduce manual testing effort through AI-assisted test generation and execution, and (3) build a high-performing automation team capable of independently owning quality for multiple release streams.

Responsibilities:

• Lead and mentor a team of automation engineers, setting technical direction, reviewing work, and driving accountability for quality deliverables
• Architect and own scalable Python-based test automation frameworks using strong OOP design principles
• Drive CI/CD pipeline integration for automated test execution using GitHub Actions or equivalent systems
• Build and maintain custom AI agents to enhance test engineering workflows — including test case generation, intelligent test selection, and quality reporting
• Follow up with multiple stakeholders across engineering, product, and release management to ensure on-time, quality releases
• Independently own automation projects end-to-end — from design through implementation, execution, and reporting
• Define and enforce automation best practices, coding standards, and test coverage strategies across the team
• Integrate automated test suites into deployment workflows to enable continuous quality feedback
• Collaborate with product and engineering teams to embed quality early in the development lifecycle

Qualifications:

Education:

• Bachelor's or Master's degree in Computer Science, Software Engineering, Information Systems, or a related technical field

Required:

• Hands-on Python development experience with strong OOP design and clean code principles
• Proven ability to architect and maintain scalable test automation frameworks from scratch
• Strong understanding of CI/CD concepts and practical experience with GitHub Actions or equivalent (Jenkins, GitLab CI, CircleCI)
• Experience building or working with custom AI/LLM agents in a test engineering or quality context
• Solid knowledge of software testing methodologies
• Experience with API test automation using REST or GraphQL (Pytest, Requests, or equivalent)
• Demonstrated ability to lead, mentor, and grow a team of automation engineers
• Ability to independently own and drive automation projects with minimal supervision
• Experience managing and following up with multiple stakeholders across engineering, product, and release management
• Proficiency with version control workflows — Git, branching strategies, pull request reviews
• Strong written and verbal communication skills for cross-team collaboration and documentation
• Experience integrating automated test suites into deployment pipelines for continuous quality feedback
• Familiarity with Agile/Scrum development practices and sprint-based delivery
• Experience with test management tools such as Jira and Zephyr Scale
• Experience with software quality engineering or test automation
