TGC Gruppe | Germany | Luxemburg (Land) Wecker | Permanent position | Full time / Home office | Published since: 13.10.2026 on stepstone.de
Lead Solution Architect Microsoft 365 & KI (m/f/d)
The TGC has been there since 2003, and we focus all our actions on one task: we digitize construction companies successfully. Not with PowerPoints and technology shortwords, but with solutions arriving at the construction site. In the case of construction managers, polishing, secretaries equally. At three locations, around 50 people work daily on the fact that digitalization in construction does not remain a key word, but works in everyday work. For this we were awarded several times as TOP CONSULTANT. But much more important than any award is us when a building manager says that we have made his everyday life easier. We work for that. You are the person who decides how to build a solution in our projects: which modules from Microsoft 365 carry, where Copilot and its own AI agencies can benefit and where not, how data, permissions and operation fit together, so that a construction company still operates the solution safely in three years. You explain your decisions so that a managing director can understand them and a developer can implement them? Perfect, then we're looking for you! !

Your tasks • Your profile • What we offer
Your role in us The place is new and is in our delivery, right at the delivery line. You are the technical counterpart for our consultants, our developers and the IT of our customers, across all projects and not bound to a customer. Your focus is on Microsoft 365, the Power Platform, Azure and Microsoft 365 Copilot, including its own AI agencies. You guide our developers professionally and accompany them until You bear the technical responsibility for their platform. Our customers operate the solutions themselves or let them operate by us: Your architectures need to work not only at the go-live, but at the plant.
You are responsible for the solution architecture in our customer projects: digital construction and project platforms on Microsoft 365, specialist applications on the Power Platform with Azure SQL, Microsoft 365 Copilot and its own AI agencies. The role is not limited to a customer. You develop target architectures for M365 environments in construction companies: tenant structure, information architecture in SharePoint and teams, identity and authorization concept in Entra ID, data classification and protection with Purview, governance for Power Platform and copilot. You're reviewing where Microsoft 365 Copilot, Copilot Studio and Azure AI Foundry benefit and where not, and tell the customer too. You unleash agents, data and grounding concepts and build the first prototypes yourself. You are the technical contact for consultants, developers and the IT of our customers: You make architectural decisions, hold them in writing (also the rejected alternatives) and make them binding in the project. You guide our developers professionally: architecture and code reviews, standards for solutions, environments, versioning and deployment. You accompany them until You bear the technical responsibility for their platform. You determine how a solution is operated: operating and support concept, monitoring, licensing, handover to the customer IT or to our company. You sit in strategy workshops and searches as a technical counterpart to management and IT management and translates between construction site, specialist area and technology. You follow the Microsoft roadmap and decide what it enters into our standards, templates and offers. You question unclear requirements and say what's missing, instead of compromising a solution. You will meet the technical decision.
You’ve built at least five years of solutions in the Microsoft ecosystem and managed at least three years of architecture: productively used, not as a pilot. SharePoint Online, Teams, Entra ID, Purview, the Power Platform (Canvas and Model-Driven Apps, Dataverse, Power Automate) and Azure (Azure SQL, Functions, Logic Apps, Key Vault) you know deeply enough to decide between them and show a developer how to do it. You have already introduced Microsoft 365 Copilot or built agents with Copilot Studio. Azure AI Foundry, RAG architectures and grounding on SharePoint and Graph data you know from your own work, not from films. You unravel authorization and data models across data, documents and process steps and know why copilot cannot go live without a clean authorization concept at the customer. You work with solutions, separate environments for development, testing and production, git and deployment pipelines. You document that the customer's IT department can operate the solution itself: architectural decisions, diagrams, operating manual. You represent your position towards managing directors like developers and change them when the better argument is on the table. For you, AI is of course part of the development as a Sparring partner. You can rule German at level C1. You're tuning with calibrators, construction leaders, builders and IT leaders. English is enough for Microsoft documentation and partner talks. You are ready to go to the customer for workshops, on average two to four days a month.
