About the role:

The Software Development Engineer (SDE) contributes in all areas of development as a member of an Agile Scrum team supporting the Customer Identity and Access Management (CIAM) and Consent and Preference Management (CPM) products. CIAM provides secure customer registration, authentication, account recovery, multi-factor authentication, passkeys, authorization, token and session management, and identity lifecycle capabilities, using Auth0 as the core identity platform. CPM enables customers to capture, manage, and enforce consent and communication preferences across channels and business applications, using Cassie as the core consent and preference platform. The team builds product-specific capabilities on top of these platforms through .NET APIs and supporting services hosted in Kubernetes. Team members will have areas of strength and some level of specialization but must be adept at learning tools and languages that enable the team member to participate in all areas of product development. Being adaptable and knowledgeable in multiple domains enables the team members to swarm or fill gaps to meet commitments.
