Application & Platform Architect (m/f/d)

Application & Platform Architect (m/f/d)

Role:

Do you want to actively shape the technical future of a business-critical information system? In this role, you combine architectural work at the application level with the technical platform beneath. You develop solution approaches for new requirements, drive the modernisation of a mature system landscape, and ensure that integrations, security mechanisms, and operational processes are sustainable in the long term.

Responsibilities:

• You develop and evaluate solution architectures for new projects, business requirements, and technical enhancements

• You are responsible for the overall technical architecture of the information system – from individual business components to the underlying ICT platform

• You design the target architecture and develop the modernisation roadmap, for example by decoupling sub-applications and replacing outdated components

• You conceptualise the integration architecture and define API designs, gateway policies, and messaging topologies for synchronous and asynchronous communication

• You consider transaction boundaries, consistency models, as well as error and restart behaviour between distributed components

• You further develop the architecture for authentication and authorisation and define overarching token flows, directory integrations, and permission processes

• You ensure that the system landscape is designed for availability, resilience, and operability across multiple instances and stages

• You define requirements for observability, monitoring, update, and maintenance strategies

• You manage external suppliers technically, assess their implementation against the agreed architecture, and negotiate suitable solution approaches

• You make technical risks and existing architectural debt transparent and represent necessary measures to business units and programme management

• You define technical standards for security, compliance, and integration and ensure their consistent application

Qualifications:

• You have a degree in computer science or a comparable qualification

• You have several years of experience in an architectural position and have already managed external suppliers technically

• You think in distributed systems and are familiar with consistency models, transaction boundaries, and error behaviour between components

• You bring solid experience in the integration architecture of heterogeneous system landscapes

• You know API design, messaging topologies, as well as synchronous and asynchronous integration patterns

• Ideally, you have worked with IBM MQ, Kafka, or comparable messaging technologies

• You have knowledge of modern identity and access architectures such as OIDC, SAML, LDAP, and RBAC

• You have experience with containerised enterprise platforms like Kubernetes or OpenShift, including tenant and stage separation

• You understand the requirements of a modern operational architecture and are familiar with topics such as observability, availability, and maintenance strategies

• Experience with document management systems and workflow engines is an advantage

• You can document, argue, and represent technical decisions understandably to different stakeholders

• You communicate very well in German and have good English skills

• Flexible working hours
• Above-average holidays and days off
• Comfortable office with modern infrastructure
• Contribution or takeover of mobile phone and notebook
• Attractive training and development opportunities
