Staff Software Engineer – Identity & Access Management

Xsolla

• Own the technical strategy and architecture of our IAM platform, covering authentication, authorization, and session management at scale. • Design and evolve our OAuth 2.0 / OIDC flows, token lifecycle, and security primitives to meet both product and compliance requirements. • Drive decisions on protocol design, data modeling, and platform reliability, and build buy-in across engineering and security teams. • Identify systemic risks and performance bottlenecks; lead initiatives to resolve them before they become incidents. • Define engineering standards, review critical code and designs, and create leverage for the team through documentation, tooling, and mentorship. • Collaborate with product, security, and infra teams to align on roadmap and translate business needs into well-scoped technical plans. • Serve as the go-to escalation point for complex production issues in the IAM domain.

Job Requirements

  • Deep understanding of OAuth 2.0, OIDC, and related auth flows: authorization code + PKCE, client credentials, device flow, token introspection, refresh strategies.
  • Solid grasp of cookie security, CSRF, XSS, token storage, TLS, and secure session management.
  • Experience designing or operating production-grade IAM or auth systems.
  • Strong Go (Golang) engineering skills: idiomatic code, concurrency patterns, performance profiling.
  • Experience with distributed systems and their trade-offs (consistency, availability, failure modes).
  • PostgreSQL: Schema design, query optimization, migrations at scale.
  • Kubernetes: Deploying, operating, and debugging services in a k8s environment.
  • Kafka or NATS: event-driven patterns, consumer groups, at-least-once delivery.
  • Git and modern CI/CD practices.
  • Proven ability to lead multi-quarter technical initiatives across teams.
  • Track record of influencing architecture and standards beyond your immediate team.
  • Ability to write RFCs and design docs that people actually read.
