Cloud Technical Architect (M/F/D)

We are looking for a Cloud Technical Architect to 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
• Ensure alignment with security, compliance, and performance requirements
• Support cloud migration strategies (rehost, replatform, refactor)
• Guide integration with existing enterprise IT landscapes (on-premise and hybrid)
• Contribute across the full lifecycle: strategy, design, and implementation

• 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)
• Experience with cloud migration strategies (rehost, replatform, refactor)
• Understanding of enterprise IT environments (SAP, legacy systems, integrations)
• Knowledge of security and compliance (IAM, data residency, sovereignty)
• Experience with cost optimization and FinOps principles

Profile:

• Self-starter who proactively drives technical initiatives
• Strong ownership of customer onboarding and architectural outcomes
• Strategic thinker with the ability to translate vision into execution
• Hands-on mindset (not a “PowerPoint architect”)
• Able to balance long-term architecture with short-term delivery

Soft Skills:

• Strong communication skills in customer-facing environments
• Ability to simplify complex technical concepts for different audiences
• Confident in leading discussions and guiding decision-making
• Challenges assumptions constructively while maintaining trust
• Strong stakeholder management across business and technical teams

All our positions are open to both women and men and are, of course, open to people with disabilities.
