About Vattenfall
Vattenfall is a European energy company with approximately 20,000 employees. For more than 100 years, we have been supplying energy to households and industries, modernizing society through innovation and cooperation.
Our ambition: to enable fossil-free living within one generation.
To achieve this, we are looking for talented specialists who combine technical expertise with strong team spirit. Within our digital products and services, Identity & Access Management (IAM) plays a key role in providing secure, reliable, and customer-friendly solutions.
Your Role
As a WSO2 IAM Developer within the Customer Recognition & Digital Identity (CRD) team, you will work at the core of our IAM landscape: the WSO2 Identity Server. You will help millions of customers access Vattenfall’s products and services securely and seamlessly — such as EV charging, solar panels, and home energy management.
Your contributions will include:
•
• Designing and extending authentication methods
• Implementing trust levels, role-based access, and session management
• Integrating WSO2 IAM with front-end applications (App & Web), .NET back-end services, and SAP systems
• Running experiments (e.g., A/B testing) to optimize login flows and user experience
• Ensuring compliance with security and accessibility standards
Key Responsibilities
•
• Develop, configure, and extend WSO2 Identity Server (authentication flows, service providers, identity federation, adaptive authentication)
• Build and optimize API-driven integrations between WSO2, .NET microservices, SAP, and Azure services
• Support Product Owners, UX specialists, and Security experts in refining customer identity and access journeys
• Implement secure and user-friendly IAM flows (MFA, self-service account management, delegated access)
• Automate CI/CD pipelines in Azure DevOps (YAML)
• Proactively monitor and improve the performance, security, and compliance of IAM services
Requirements
Must-haves

• Strong experience with WSO2 Identity Server (configuration, customization, extensions)
• In-depth knowledge of OIDC, OAuth2, SAML, SCIM
• Proficiency in Java (for WSO2 custom extensions) and API integration with .NET/REST services
• Familiarity with Microsoft Azure services (Web Apps, API Management, Container Apps, Cosmos DB)
• Solid understanding of IAM security practices (MFA, adaptive authentication, delegated authorization, session security)
Nice-to-haves
