Senior Consultant/Management Consultant – Infrastructure & Cloud Sourcing Advisory – DACH

Position Overview

We are looking for an experienced management consultant with profound expertise in infrastructure and cloud – spanning public, private, and hybrid cloud architectures, modern datacenter services, and emerging models such as edge computing. You will advise clients on how to architect, source, transform, and optimize their infrastructure and cloud ecosystems, helping them improve performance, resilience, cost efficiency, and agility.

In this senior role, you will lead client-facing workstreams, shape cloud and infrastructure sourcing strategies end-to-end, run complex tenders, manage vendor evaluations, and guide clients through commercial and technical decision-making. You will also mentor junior team members and contribute to thought leadership in the DACH region.

If you combine consulting discipline with technical depth in infrastructure and cloud, and want to shape high-impact transformation programs, this role offers autonomy, visibility, and a clear progression path within ISG.

Lead cloud and infrastructure–focused sourcing and transformation workstreams across public cloud, private cloud, hybrid architectures, datacenter services, network transformation, and edge deployments, including how AI changes workload requirements, service delivery, and sourcing decisions.

Develop cloud and infrastructure sourcing strategies, business cases, technical/functional requirements, and commercial models.

Manage end-to-end RfX processes (RFI, RFP, RFQ), vendor assessments, solution comparisons, and contract/price negotiations.

Assess providers’ cloud/infrastructure capabilities, operating models, and service architectures using ISG benchmarks, data, and AI-supported insights, validating outputs and claimed productivity gains while protecting confidential client information.

Help clients define future-state cloud and infrastructure operating models, including governance, service integration, and transition planning.

Facilitate workshops on cloud strategy, infrastructure modernization, edge adoption, and service design for senior stakeholders.

Coach junior consultants and ensure quality across deliverables and analyses.

Contribute to proposals, thought leadership, and the development of ISG’s cloud and infrastructure sourcing methodologies.

Collaborate with international teams across consulting, research, benchmarking, and managed services.
