- Ensure AI usage supports secure, responsible, and compliant engineering practices.
Responsibilities
- Contribute to planning, estimation, and refinement of stories, epics, and design changes as part of an Agile Scrum team.
- Design and build scalable automated test frameworks to validate REST APIs, SDKs, and microservices within the Identity Platform.
- Develop test strategies and coverage plans for core identity workflows including login, MFA, SSO, and delegated access.
