We are seeking a visionary Staff Software Engineer – Identity & Access Management to architect, build, and scale the foundational security layer of our global ecosystem. In this role, you will take full ownership of our authentication and authorization infrastructure, ensuring that millions of users can securely interact with our services. Working at the intersection of security, platform stability, and developer experience, you will lead the design of mission-critical systems—from identity federation and complex token lifecycles to fine-grained access control models.
This is a high-impact position for an engineer who excels in the Golang ecosystem and thrives on the complexity of high-stakes security systems. You aren’t just implementing protocols; you are building a resilient, multi-tenant identity fabric that supports everything from global gaming integrations to sophisticated SaaS architectures. If you have a deep-seated passion for data privacy, a "security-first" mindset, and the technical depth to navigate the nuances of OAuth 2.0, OIDC, and beyond, you will find a home here.

Decade of Experience: 10+ years in backend or systems engineering, with at least 5 years dedicated to the Identity & Access Management (IAM) domain.
Golang Mastery: Expert-level proficiency in Go, with a track record of building high-performance, concurrent, and scalable distributed systems.
Cloud-Native Mindset: Proven experience deploying and managing services within Kubernetes environments (AWS or GCP).
Identity & Security Deep-Dive
Auth Protocols: Deep architectural understanding of OAuth 2.0, OIDC, JWT, and SCIM.
Lifecycle Management: Hands-on experience with identity federation, sophisticated token management, and complex access control flows.
Security First: Strong grasp of modern security best practices, encryption standards, and secure coding principles.
Advanced Auth Models: Experience implementing fine-grained access control such as ReBAC, ABAC, or utilizing Open Policy Agent (OPA).
Ecosystem Knowledge: Familiarity with industry-leading identity providers and frameworks like Ory (Kratos/Keto), Keycloak, Auth0, or ForgeRock.
Scale & Architecture: Background in building multi-tenant architectures, specifically for global SaaS platforms or large-scale Gaming ecosystems.
Community Footprint: Active contributions to Open Source Golang projects or security-focused libraries.
