[Hiring] Senior Cloud Platform & Solution Architect @Nemensis Ag

Role Description

For our client, we are looking for a “Senior Cloud Platform & Solution Architect” (m/f/d).

Our client is preparing the migration and modernization of a productive, business-critical data-processing application. The objective is to assess suitable cloud, container, and hybrid platform alternatives and recommend the best feasible option.

The assignment focuses on an application-specific assessment and the preparation of an actionable implementation package. It is not a general cloud or enterprise platform strategy project.

Framework Parameters:

• Project period: 1 October–31 December 2026, with the option to extend
• Location: 90% remote and 10% onsite in Berlin during RampUp
• Project language: English

Tasks:

• Define application-specific requirements, decision criteria, assumptions, scope boundaries, and mandatory exclusion criteria.
• Analyze the existing and planned application architecture, components, interfaces, connectivity, data flows, and operational requirements.
• Assess suitable Microsoft Azure, OpenShift/Kubernetes, and hybrid platform alternatives, including Azure data services and managed platform services.
• If required, conduct a limited assessment of suitable sovereign European cloud alternatives.
• Evaluate the technical, legal, security, data-protection, governance, and operational feasibility of each option.
• Assess the availability and suitability of technologies such as Azure Databricks, Spark, Kafka, object storage, Delta Tables, and related integration services.
• Identify required changes to the application, platform, interfaces, connectivity, identity and access management, and security controls.
• Determine the necessary platform ownership, support model, service levels, responsibilities, skills, and resources.
• Identify blockers, prerequisites, dependencies, approvals, risks, procurement requirements, and indicative implementation and operating costs.
• Compare the alternatives using consistent criteria and provide an evidence-based recommendation.
• Develop an actionable implementation package, including a high-level target architecture, prioritized backlog, roadmap, responsibility model, resource and budget estimates, and risk and dependency overview.
• Prepare management-ready documentation to support the final decision and subsequent implementation.

Qualifications

• Several years of senior-level experience in cloud, platform, and solution architecture for productive, business-critical applications.
• Proven experience with platform assessments, cloud migrations, target architectures, and implementation planning.
• Strong expertise in Microsoft Azure and Azure data services, particularly Azure Databricks or comparable data-processing platforms.
• In-depth knowledge of Red Hat OpenShift, Kubernetes, containerized workloads, operators, and managed services.
• Experience designing and assessing hybrid cloud and platform architectures.
• Strong knowledge of Spark, Kafka, object storage, Delta Tables or equivalent technologies, and data-integration patterns.
• Sound understanding of cloud security, identity and access management, data protection, data residency, and governance.
• Experience defining platform operating models, ownership structures, support responsibilities, and service levels.
• Ability to assess complex technical options, identify critical blockers, and provide transparent, evidence-based recommendations.
• Experience working in regulated, security-sensitive, or business-critical environments.
• Strong stakeholder-management, workshop-facilitation, and management-presentation skills.
• Fluent English is required; German language skills are a plus.
• Relevant Azure, OpenShift, Kubernetes, security, or architecture certifications are a plus.
