Staff Engineer - Authentication & Authorization; f​/m​/x

Job Description

Role Mission

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

• Millions of device, user, and service interactions are secure by design
• 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 the Identity Architecture

• Own the end-to-end authentication and authorization model across Enpal systems.
• Design scalable identity solutions for customer platforms and mobile/web apps, internal operational tools and partner integrations, machine-to-machine and event-driven communication.
• Establish patterns for multi-tenant identity and access control across markets and product lines.

Build a Secure-by-Default Platform

• Lead implementation of modern protocols (OAuth2, OIDC, mTLS, SAML where required).
• 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.
• Mentor teams on correct usage patterns and security best practices.
• 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.

We are looking for roughly a 50% fit with what we ask. The other 50% is the perspective and strengths you bring.

• 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 including the ability to translate security requirements into practical engineering solutions.
• Feel comfortable with:
  Azure, Kubernetes, Terraform.
• You communicate clearly in English, spoken and written. Crisp and concise ways of formulating your ideas and opinions. Knowledge of German is a plus.
• You are inspired by the energy transition and want to make a difference. We are one of the biggest players in the solar business and want to make this change with you.
• You want to participate in a company where empowerment and initiative is valued. We are looking for people who want to grow their personal skills and knowledge, take responsibility, steer and influence for what they feel is right.
• Agile and lean values are embodied by you. People over processes.

Hybrid work model – you can choose office or home, even after the pandemic.
