The Domain Architects Architect acts as a trusted advisor partnering with the customers on their needs. Understands and captures the critical inputs of stakeholders and translates them into effective requirements and solutions. Specifies and designs effective end-to-end solutions incl. customer-specific adaptations by using the Nokia portfolio of products, systems and / or services as well as 3rd party products where required. Applies solution architecture standards, processes, and principles to create and maintain a solution's (technical) integrity over time. The Domain Architect leads end-to-end solution architecture for customer programs within the Telecom domain. This role defines, designs, and governs complex architectures across Cloud Native Solutions and emerging 5G/6G technologies—ensuring technical integrity, customer value, scalability, and lifecycle sustainability

 

Architecture & Solution Design

• Translate functional and non-functional requirements into scalable, secure, and performant architectures.

• Ensure architectural alignment with industry standards (3GPP, ETSI, TM Forum, CNCF).

• Govern architecture integrity throughout project lifecycle, ensuring compliance, consistency, and extensibility.

Cloud & DevOps Leadership

• Design customer-specific cloud architectures on NCP, OCP, NCOM, and public cloud platforms (AWS, GCP/GKE).

• Provide hands-on expertise in Cloud Native, Kubernetes, CaaS, microservices, and container orchestration.

• Collaborate with cloud integrators on deployment, troubleshooting, and performance optimization.

• Lead DevOps initiatives using CI/CD, GitOps, automation pipelines; experience with Terraform, Crossplane, CloudFormation highly valued.

Customer Engagement & Requirements Management

• Capture, validate, and manage customer requirements, ensuring alignment across Business Groups.

• Drive stakeholder workshops, architecture reviews, and technical discussions.

• Influence customer technical strategy and participate in key solution selling and pre-sales engagements.

Cross-Functional Collaboration

• Coordinate cross-BG/BU architecture components to build cohesive, interoperable solutions.

• Collaborate with Network Planning, R&D, Product Line, and Delivery teams for solution feasibility and efficiency.

• Provide architectural guidance across multi-disciplinary engineering teams.

Thought Leadership & Strategic Contribution

• Contribute to technology strategy, solution blueprints, and reference architectures.

• Lead initiatives on emerging trends such as 5G Core evolution, 6G systems, Network Slicing, O-RAN, Edge Computing, and Cloud Native Telco.

• Act as senior technical mentor; coach engineering and integration teams on best practices.

• Solve complex architectural challenges through advanced analytical and domain expertise.

Technical Expertise

• Strong background in Telecom Cloud, 5G SA/NSA Core, Telco CNFs/VNFs, and Cloud Native architecture.

• Expertise in Kubernetes, CaaS platforms, service mesh, and observability frameworks.

• Hands-on experience with CI/CD, automation tools, and Infrastructure-as-Code (Terraform/Crossplane/CloudFormation).

• Solid understanding of Telco protocols (SBI, Diameter, GTP, SCTP), Network Slicing, and Edge/MEC.

• Cloud implementation experience in AWS, GCP/GKE, or similar platforms.
   

Professional & Leadership Skills

• Strong techno-managerial experience in complex architecture delivery programs.

• Ability to lead multi-functional technical teams and manage architecture governance.

• Strong analytical, problem-solving, and decision-making skills.

• Excellent communication and customer-facing capabilities.

  • Drive innovation-led architecture thinking, introducing modern design patterns, automation frameworks, and cloud-native accelerators to reduce delivery overhead and improve long-term maintainability.
  • Identify architecture reuse opportunities (blueprints, modules, CI/CD templates, IaC patterns) to minimize rework, reduce cycle time, and improve overall engineering efficiency.
  • Evaluate emerging technologies—such as AI-driven orchestration, autonomous networks, 5G/6G advanced features, and edge intelligence—to enhance solution competitiveness and customer value.
  • Develop forward-looking technology roadmaps that support customer business evolution while optimizing cost-to-serve and maximizing ROI.
  • Implement architecture governance practices to ensure early defect detection, dependency minimization, and alignment across BUs/BGs—drastically reducing late-stage redesigns.
  • Introduce metrics-driven decision-making (architecture KPIs, TCO tracking, cloud efficiency metrics) to optimize architecture choices and financial sustainability.
  • Promote a culture of experimentation and prototyping (PoCs, innovation sprints) to validate concepts early and avoid downstream effort wastage.
  • Partner with Product Management and Customer teams to identify new value streams, upsell/cross-sell opportunities, and scalable solution components that enhance recurring revenue.
  • Apply strategic risk assessment and scenario analysis to guide technology investments that yield measurable business benefits for both customer and organization.

Strategic Contribution, Innovation & Continuous Optimization

• Solves complex problems based on sophisticated analytical thought and complex judgment.

• Contributes to development of concepts to determine professional direction of own organisational unit.

• Acts as a professional leader for staff / workteam / taskforces, often the most senior specialist in a team, who serves as best practice resource within own organisational unit and / or is recognised as an expert within the same professional area in the business.

• Often leads functional teams or projects with moderate resource requirements, risk and complexity, handles day-to-day staff management issues, including resource management and allocation of work.
