The Hybrid Cloud Solution Architect will join the team that designs, builds and operates Siemens Healthineers’ global Multi‑Cloud (Microsoft Azure & AWS) and on‑premises environments. This role has two core focuses: architecting scalable, secure platforms for AI and high‑performance computing (HPC) workloads and designing robust general cloud infrastructure architectures to support enterprise applications and services.

• Design, build and maintain cloud systems on Azure and AWS using all available services with a focus on PaaS, while also architecting platforms and reference architectures specifically for AI and high‑performance computing (HPC) workloads.
• Build solutions that provide availability, performance and stability in our systems, services and products at scale, including support for large‑scale model training, inference, and HPC simulations.
• Work in conjunction with our demand teams, data science/HPC teams and business users to understand functionality, scalability, performance, security and integration requirements for both application and AI/HPC use cases.
• Propose architectures using native Azure/AWS services, automation and serverless technology in a complex multitenant environment; include GPU/accelerator provisioning, distributed compute patterns, storage tiering and high throughput/low latency networking when required for AI/HPC.
• Collaborate within the organization to build secure IaaS, PaaS and SaaS environments in Azure and AWS that also accommodate AI/HPC operational requirements.
• Define migration solutions for existing on‑prem hosted software development processes (CI/CD landscapes), including pipelines and practices for ML model lifecycle (training, validation, deployment) and reproducible HPC workflows.
• Understand Siemens Healthineers information security requirements and drive adherence for cloud workloads, applying specific controls and governance needed for sensitive data used in AI and HPC workloads.
• Develop and maintain documentation for built Azure/AWS systems and procedures, and include runbooks, capacity planning guidance and tuning tips for AI/HPC jobs and large data pipelines.
• Craft and evangelize secure cloud platform and product requirements, incorporating cost management and performance optimization strategies for compute intensive workloads.
• Embrace a culture of continuous service improvement and service excellence, with regular reviews of platform performance, cost and reliability.
• Stay current on cloud industry trends, emerging technologies, and best practices.

• Overall 10+ years’ experience in cloud technologies (Azure & AWS), with the most recent 3 years on AI & HPC services.
• Proven experience designing hybrid cloud architectures for AI/ML and high‑performance computing (HPC) use cases.
• Experience implementing enterprise‑grade cloud solutions, including hybrid integration with on‑premises compute and storage.
• Strong knowledge of cloud networking and application security, infrastructure hardening, security baselines, web server and database security.
• Knowledge of Azure and AWS Cloud security strategies, tools and compliance frameworks, with the ability to apply IAM, encryption and network segmentation to compute‑intensive workloads.
• Ability to communicate clearly and effectively on status, progress and risks to both technical and non‑technical stakeholders.
• Bachelor’s degree in computer science or a related field, or equivalent practical experience.
• AWS Cloud Architect and Azure Solutions Architect Expert certifications preferred; additional AI or security certifications are a plus.
• Knowledge of large‑scale software development and CI/CD processes, including ML model CI/CD and reproducible workflows, is a plus.
• Demonstrated experience building reliable, scalable, secure,…
