CLOUD TECHNICAL ARCHITECT

You translate business requirements into scalable, secure, and future-proof solutions that align with enterprise standards and long-term goals.

This role requires strong architectural expertise combined with a solid understanding of cloud platforms and networking fundamentals (including the TCP/IP stack), as networking forms a critical foundation of the platform.

You will be working with T-Systems’ own cloud platform (T Cloud Public – TCP), which is comparable to hyperscalers such as AWS. However, as this is a proprietary platform, it requires the ability to quickly understand new architectures and technologies. Candidates with a background in AWS, Azure, or GCP are welcome, but should be comfortable adapting to a different ecosystem.

The environment is dynamic and evolving: you will be part of a relatively small, entrepreneurial core team (5–6 people) within T-Systems, helping to shape both the platform and the go-to-market approach (across the Netherlands and Germany). This is not a fully matured environment—success requires a proactive, hands-on mindset and the motivation to build, improve, and influence.

Key Responsibilities

• Design end-to-end cloud architectures within T-Systems Public Cloud (TCP)
• Translate business needs into scalable, secure, and future-proof technical solutions
• Define and implement landing zones and reusable architectural patterns
• Guide customers in onboarding and workload design on the platform
• Advise on platform choices, cost optimization, risks, and time-to-market
• Support cloud migration strategies (rehost, replatform, refactor), including multi-cloud and hybrid scenarios
• Lead technical discussions across all levels, from C-level stakeholders to engineering teams
• Operate in a highly versatile role: from on-site customer advisory (e.g. public sector or regulated enterprises) to delivering technical presentations
• Ensure alignment with security, compliance, and performance requirements, especially within regulated industries (e.g. finance, SaaS, IP-heavy organizations, public sector)
• Contribute to shaping the platform, architecture standards, and overall product quality
• Collaborate closely with internal stakeholders including the Managing Director, T Cloud Public Lead, Solution Designers,

Job Requirements

Required Skills & Experience

• Solid experience in cloud architecture (IaaS, PaaS, containers, Kubernetes)
• Experience with cloud platforms comparable to AWS, Azure, or GCP
• Ability to quickly understand and adapt to new cloud platforms (experience beyond one ecosystem is a plus)
• Good understanding of the TCP/IP stack and networking fundamentals
• Strong networking knowledge (connectivity, latency, routing, DNS, hybrid architectures)
• Experience with cloud migration strategies (rehost, replatform, refactor)
• Understanding of enterprise IT environments (including legacy systems and integrations)
• Knowledge of security and compliance (IAM, data residency, sovereignty), preferably in regulated environments
• Experience with cost optimization and FinOps principles

Profile

• Holistic, technically strong architect (not purely enterprise-focused, but hands-on capable)
• Able to operate across domains: architecture, platform design, and customer engagement
• Comfortable working in an environment that is still being built—able to create structure where it does not yet exist
• Eager to influence product quality, platform maturity, and ways of working
• Entrepreneurial mindset; thrives in a scale-up-like environment within a large organization
• Not a “PowerPoint architect”—able and willing to engage deeply with technology
• Strong self-starter who takes ownership and drives initiatives forward
• Able to balance long-term architectural vision with short-term delivery
• Comfortable switching contexts: from strategic advisory to technical deep dives

Soft Skills

• Strong communication skills in customer-facing environments
• Ability to simplify complex technical concepts for different audiences
• Confident in engaging with both engineers and senior stakeholders (including C-level)
• Constructively challenges assumptions and is not afraid to push back when needed
• Strong stakeholder management across business and technical teams
• Resilient and pragmatic—does not get discouraged by ambiguity or evolving structures
