About the role

As a Staff Engineer for Authentication & Authorization, you will define and lead the identity and access strategy across Enpal's digital and device ecosystem.

What you'll do

• Own the end-to-end authentication and authorization model across Enpal systems and design scalable identity solutions for customer platforms, internal operational tools, partner integrations, and machine-to-machine communication.
• Lead implementation of modern protocols (OAuth2, OIDC, mTLS, SAML where required) and define standards for fine-grained authorization and secure API access.
• Create reusable libraries, SDKs, and guardrails that make the secure path the easiest path.
• Design identity-aware infrastructure aligned with Zero Trust principles and integrate authentication into Azure and Kubernetes environments.
• Provide a shared identity platform used by multiple engineering domains and mentor teams on correct usage patterns and security best practices.
• Support GDPR-aligned identity handling and implement traceable authorization decisions and audit logging.

What you'll need

• 8+ years in software engineering, including experience designing distributed systems.
• Proven experience designing or operating authentication and authorization systems at scale.
• Strong background in cloud-native architectures and microservices.
• Hands-on experience implementing identity protocols such as OAuth2, OIDC, or similar.
• Experience designing secure service-to-service communication patterns and translating security requirements into practical engineering solutions.
• Comfortable with Azure, Kubernetes, and Terraform.
• Clear English communication skills, spoken and written.
