Senior Cloud Native Architekt (m/w/d) (Ref.Nr.: 46987)

About the Role

We are seeking a Senior Cloud Native Architect for a Proof of Concept (PoC) project to realize an internal Kubernetes platform. The objective is to conceptualize and prototypically implement functionalities for providing operational data to external recipients, with a strong focus on architecture, security, and integration aspects for highly available, 24/7-critical applications.

Key Facts

• Start: 2026-07-01
• Duration: Not specified
• Utilization: 0%
• Location: Berlin, Germany
• Work Model: 95% remote, 5% on-site

Your Tasks

• Develop a shared understanding of the project's goals, scope, and expected outcomes.
• Analyze the framework conditions of the internal cloud-native Kubernetes platform concerning development, operation, security, and integration.
• Design a platform-compliant reference architecture for exchanging operational data between transmission system operators.
• Outline the solution design for highly scalable data exchange, handling up to approximately 100,000 information items per second.
• Consider requirements for high availability, scalability, observability (monitoring), and IT security for critical KRITIS applications.
• Define suitable integration patterns for data exchange between internal systems, platforms, and external partners.
• Conceptualize and prototypically implement data provision from existing sources.
• Establish the forwarding and distribution of data via event-based mechanisms like Apache Kafka.
• Design an architecture for receiving, processing, and distributing sensor data.
• Technically implement core functionalities and develop a Minimum Viable Product (MVP) as a reference implementation.
• Develop a pragmatic, iterative process model to identify necessary roles and competencies.
• Comprehensively document the chosen architecture, design decisions, technical implementation approaches, and create guidelines.

Must-Have Requirements

• Extensive experience in overall technical responsibility for .NET and Java-based applications in complex, distributed, and highly scalable system landscapes.
• Strong architectural competence in conceptualizing, evaluating, and managing scalable, highly available, and secure application and data architectures.
• Expertise in Big Data processing, particularly in the design and use of frameworks like Apache Spark (batch and streaming processing).
• Experience with processing very large data volumes (high throughput / high velocity), including performance optimization, resource management, and fault tolerance.
• Solid understanding of event-driven and data-driven architectures, including combining streaming platforms (e.g., Kafka) with Big Data processing frameworks.
• Proficiency with cloud and platform-native operating models, including containerized Big Data workloads on platforms like Azure, AWS, or GCP.
• German language proficiency at C2 level and English language proficiency at C1 level.

Nice-to-Have Requirements

• Experience in designing integrated data pipelines, from data ingestion (e.g., sensors, files, streams) through processing and enrichment to distribution.
• Experience in the secure design of data processing solutions for 24/7 KRITIS operations, including resilience, restart concepts, and monitoring.
• Proven responsibility for non-functional requirements such as scalability, performance, data consistency, latency, and operational security.
• Ability to translate complex business requirements into robust, future-proof data and application architectures.
• Strong communication and moderation skills for transparently representing architectural decisions, technical risks, and effort estimates to management and business departments.
• Demonstrated experience in structured documentation of architectural and technology decisions, especially for governance, audit, and compliance purposes.
• Proven SÜG (Ü2) clearance.
