Staff Engineer – Authentication & Authorization (f/m/x)

At Enpal, we are building the largest renewable energy community in Europe — and we need a resilient, compliant, and well-governed Salesforce platform to support that scale. As a Senior Salesforce Administrator, you will focus on platform stability, data protection, access governance, and operational excellence across our Salesforce ecosystem. Your work will ensure that Salesforce remains secure, audit-ready, and built for long-term scalability.

Role Mission

This role is critical to ensuring that:

• Our platform scales safely across customers, partners, installers, and internal operations 

• Identity becomes a shared platform capability, not reinvented per team 

• We meet evolving compliance, privacy, and security requirements while maintaining developer velocity 

You will operate as both an architect and a hands-on engineer, shaping how identity, trust, and access are implemented across cloud services, IoT infrastructure, and customer-facing applications

• Define standards for: 

• Fine-grained authorization (RBAC / ABAC / policy-based access) 

• Secure API access and gateway enforcement 

• Create reusable libraries, SDKs, and guardrails that make the secure path the easiest path 

Drive Zero-Trust and Cloud-Native Security Practices 

• Design identity-aware infrastructure aligned with Zero Trust principles 

• Integrate authentication into our Azure and Kubernetes environments 

• Secure event-driven systems and messaging infrastructure 

• Collaborate with security teams on threat modeling and risk reduction 

Enable Teams Through Platform Thinking 

• Provide a shared identity platform used by multiple engineering domains 

• Reduce duplication by standardizing authentication flows and access decisions

• Balance strong security guarantees with usability and developer experience 

Ensure Compliance, Privacy, and Auditability 

• Support GDPR-aligned identity handling and data minimization strategies 

• Implement traceable authorization decisions and audit logging 

• Contribute to regulatory and certification readiness
