Cloud Technical Architect

About the Role As a Cloud Technical Architect, you guide customers in making strategic decisions about their cloud architecture within the T-Systems Public Cloud environment. You translate business requirements into scalable, secure, and future-proof solutions that align with enterprise standards and long-term goals. This role requires deep architectural expertise combined with a strong understanding of the TCP/IP stack, as networking forms a critical foundation of the platform and is comparable in complexity to hyperscalers such as AWS. Key Responsibilities

• Design end-to-end cloud architectures within T-Systems Public Cloud
• Translate business needs into scalable, secure, and future-proof technical solutions
• Define and implement landing zones and reusable architectural patterns
• Advise on platform choices, cost optimization, risk, and time-to-market
• Lead technical discussions across all levels, from C-level stakeholders to engineering teams

• Guide integration with existing enterprise IT landscapes (on-premise and hybrid)
• Contribute across the full lifecycle: strategy, design, and implementation Required Skills & Experience
• Strong expertise in cloud architecture (IaaS, PaaS, containers, Kubernetes)
• Experience with cloud platforms comparable to AWS, Azure, or GCP
• Deep understanding of the TCP/IP stack (core requirement)
• Strong networking knowledge (connectivity, latency, hybrid architectures, routing, DNS)
