Domain Architect
- Application Deadline: April 4, 2026
- Stockholm
Do you want to help shape the future of Tre’s IT landscape? We are now looking for an experienced and driven Domain Architect to take architectural leadership in our transformation program around our Customer engagement and Sales & Marketing area.
About the role
As a Domain Architect you hold the overall architectural responsibility for our CRM and Sales domain and play a central role in one of our most important transformation journeys. You lead the architectural direction as we move from custom-built solutions to a modern, data‑driven and standardized CRM ecosystem.
You are responsible for defining and realizing the target architecture, ensuring coherence and continuous development as business needs evolve. This includes close collaboration with sales as well as daily interaction with product teams, developers and other architects. You support teams in creating and following relevant roadmaps and ensure that initiatives and projects are feasible through early assessments of technology choices, risks, regulatory considerations and design requirements. Once the initial transformation is in place the role transitions into long‑term domain ownership where you drive the roadmap, target architecture, and ongoing evolution of the domain.
A key part of the role is understanding the current architectural landscape, identifying gaps and driving the organization toward future solutions. You also contribute to developing and refining our architectural standards, policies and guidelines and play an active role in raising architectural maturity across the organization.
This role can be based in Stockholm, Gothenburg or Malmö.
