ABOUT YOU

Xsolla is seeking a Principal Engineer with deep expertise in Identity and Access Management (IAM) and Golang backend development to lead the evolution of our authentication and authorization stack — enabling developers and players to connect safely and effortlessly across the Xsolla ecosystem.

•  Architect and lead the design of Xsolla’s next-generation identity platform, supporting authentication, authorization, single sign-on (SSO), and account federation across internal and external services.
•  Develop high-performance Golang microservices that manage user identity, access tokens, and permission enforcement at global scale.
•  Collaborate closely with security, DevOps, and platform engineering teams to embed Zero Trust principles and standardize access governance across services.
•  Integrate modern IAM standards and protocols (OAuth2, OIDC, SAML, SCIM) to enhance developer experience and partner integrations.
•  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.

•  10+ years in backend or systems engineering, including 5+ years designing and implementing IAM or authentication services.
•  Expert-level skills in Golang, with experience building and scaling distributed, event-driven microservices.
•  Proven track record with identity federation, token management, and access control systems.
•  In-depth understanding of authentication and authorization standards (OAuth 2.0, OIDC, SAML, JWT, SCIM).
•  Solid grasp of security principles, encryption, key management, and secrets management systems (e.g., HashiCorp Vault, AWS KMS).
•  Experience building high-availability systems in Kubernetes-based environments using AWS, GCP, or Azure.
•  Strong architectural vision with the ability to influence cross-team design and technology direction.
•  Excellent communication and collaboration skills across distributed teams.

•  Experience building or contributing to identity systems for gaming or SaaS ecosystems.
•  Familiarity with multi-tenant architectures, RBAC/ABAC models, and policy-as-code (OPA, AuthZ frameworks).
•  Background in security engineering, DevSecOps, or compliance automation.
•  Contributions to open-source Golang or IAM projects.
