Mentor and coach engineering teams on secure service design, identity best practices, and cross-service communication patterns.
Partner with product teams to ensure that identity-related features — such as player login, entitlement management, and account linking — are scalable, compliant, and user-friendly.
Define and enforce API and data security standards, supporting compliance initiatives such as GDPR, SOC 2, and ISO 27001.
Evaluate and integrate third-party IAM frameworks or open-source solutions (e.g., Keycloak, Auth0, ForgeRock) as part of Xsolla’s hybrid identity strategy.
