It reflects their pioneering spirit combined with our long history of engineering in the ever-evolving healthcare industry. We offer you a flexible and dynamic environment with opportunities to go beyond your comfort zone to grow personally and professionally. Sounds interesting?

Then join our “Graph & Ontology Platforms" team as a Lead Solution Architect!

The “Graph & Ontology Platform" is a central IT service within Siemens Healthineers that provides a platform for data and non-data scientists in our Business Units to analyze and learn from their data utilizing the power of graphs and semantic engineering.

Our goal is to enable diverse use cases across all of Siemens Healthineers regardless of whether they utilize graphs for visualization, analytics, backends or as input for AI Systems.

As part of the Center of Excellence for Data and AI, you will design and drive the implementation of the solution architecture for the Ontology platform, an upcoming extension to the Graph Ecosystem at Siemens Healthineers.

Your tasks and responsibilities:

• Design and build up the solution architecture of the new Ontology Platform within Siemens Healthineers

• Improve and extend the solution architecture of the existing Graph Platform based on Neo4j

• Design and document comprehensive solution architectures, including context diagrams, data flows, interface specifications, and deployment views in alignment with system requirements

• Define and oversee the implementation of API specifications, data integration, and federation concepts

• Create and align implementation roadmaps, ensuring the timely and effective realization of architecture plans and milestones

• Establish and enforce architectural frameworks for data access, materialization versus virtualization, user roles, automation, logging, monitoring, and compliance with regulatory requirements

• Lead cross-system integration efforts, coordinating with tool-specific experts and use case teams to ensure seamless collaboration and technical consistency

• Support service architecture planning and operational concepts, working closely with service owners, domain experts, managers and vendors

• Guide and support development teams in building system components, such as data connectors and integration solutions for various enterprise platforms (e.g., Teamcenter, Polarion, Snowflake, SAP)

• Conduct proof-of-concepts, performance tests, scalability assessments, and data migration activities

• Define governance structures and support organizational setup, enabling effective use case implementation

• Support in the creation of solution architectures for graph use cases distributed over different business areas and domains

• Ensure and extend platform capability to implement above mentioned use case architecture
