Shape the future technology landscape at Tre
Tre is strengthening its architecture function to support major transformation initiatives across Sweden and Denmark.
We are modernising our technology landscape, investing in cloud, AI, digital capabilities and long-term architecture to support future growth.
As part of this journey, we're looking for a Technology Architect, Integration, API & Event Platforms who wants to help shape the future of one of the Nordic region's leading telecom operators.
Tre's customer, commercial, network and data capabilities depend on secure, resilient and reusable integration. In this role, you will define and govern Tre's enterprise integration direction across Sweden and Denmark.
You will own the standards, patterns and roadmaps that help teams connect platforms, applications and services without creating unnecessary complexity.
About our architecture community
At Tre, architecture is evolving into a stronger advisory capability with greater influence across business and technology.
Our architects help create clarity, guide strategic decisions and connect long-term direction with practical execution. You will work alongside Enterprise Architects, Domain Architects, Technology Architects, engineering teams and senior leaders to shape the future technology landscape across Sweden and Denmark.
This is an opportunity to join a growing architecture community with increasing impact on technology strategy, transformation initiatives and business outcomes.
About the role
As our Technology Architect, Integration, API & Event Platforms, you will own the enterprise architecture direction for APIs, integrations and event-driven platforms across Sweden and Denmark.
Your scope includes APIs, events, messaging, streaming, integration security, observability and legacy modernisation.
The role combines strategic platform direction with practical guidance for engineering teams. You will define reusable standards and paved roads that make preferred integration approaches easier to adopt while ensuring that exceptions remain visible and manageable.
You will collaborate closely with Domain Architects, Security and IAM teams, platform teams, Solution Architects, Tech Leads and major transformation programmes.
What you'll do
In this role, you will:
- Define and evolve Tre's enterprise integration, API and event architecture.
- Establish standards and patterns for APIs, messaging, streaming and event-driven solutions.
- Define architecture direction for API management, gateways, event platforms and observability.
- Drive legacy modernisation and reduce unnecessary point-to-point integrations.
- Establish reusable service, ownership, versioning and lifecycle principles.
- Support Solution Architects and Tech Leads with practical architecture guidance.
- Embed security, authentication and authorisation principles into integration architecture.
- Define roadmaps, standards, Architecture Decision Records and governance models.
You can look forward to:
- A central role in one of Tre's most important cross-cutting technology capabilities.
- The opportunity to influence integration decisions across customer, BSS, OSS, data and enterprise platforms.
- Working with APIs, event-driven architectures, messaging platforms and modern integration patterns.
- Close collaboration with engineering, platform and architecture teams.
- The opportunity to create reusable paved roads that improve delivery speed and quality.
- Being part of a growing architecture function with increasing influence on strategic business and technology decisions.
Mats describes himself as a leader:
"I believe great architects create clarity rather than complexity. We provide advisory and 'marriage counseling' for IT and Business. I value curiosity, accountability and collaboration, and I encourage people to challenge established ways of working when there is a better path forward. My role as a leader is to provide direction, remove obstacles and create an environment where people can have real impact and grow in their area of expertise."
