Senior Java Software Engineer (Security)

A bit about the role

We’re looking for a talented Senior Software Engineer with solid experience and knowledge in application security to join our growing team in Zurich, Switzerland. In this role, you’ll work alongside experienced engineers and product specialists in a collaborative, agile environment where engineering quality, reliability, and maintainability are key.

The ideal candidate combines solid software engineering experience with a good understanding of application and platform security. We are not necessarily looking for a specialist in a particular security technology. More important is someone who understands secure software design, security principles, vulnerabilities, and the challenges of building and maintaining security-sensitive enterprise applications.

You will primarily focus on designing, developing and maintaining robust Java-based components, libraries and services used across Avaloq applications. The products operate within the application-security domain, giving you the opportunity to work on solutions and concepts related to authentication and authorization, JWT, Identity and Access Management, secure service-to-service communication and standards-based security integrations.

Your key tasks

• Design, develop and maintain scalable, reliable and secure Java-based components, libraries, APIs and services
• Write clean, testable and maintainable code that follows established engineering practices and architectural standards
• Analyse existing and legacy solutions and progressively improve their architecture, quality and maintainability
• Contribute to products and projects involving authentication, authorization, JWT, IAM integrations and service-to-service communication
• Design and implement new features, including preparing comprehensive solution designs
• Investigate and resolve complex technical issues across application, integration and security-related areas
• Work with security concepts such as tokens, claims, certificates, keys and trust relationships
• Participate in architecture discussions, technical reviews and code reviews
• Improve automated testing, CI/CD integration, dependency management and software quality controls
• Maintain clear technical documentation and contribute to knowledge sharing within and across teams
• Collaborate with engineering, architecture, security and product teams consuming the shared components

The role’s product area includes Avaloq’s evolution toward standards-based, vendor-independent IAM integrations, JWT compatibility and secure communication between applications and services.
