When you work with us, you’re part of a global mission to connect people, solve complex challenges, and create a sustainable and more inclusive world. If you want to grow your career whilst finding the perfect balance between work and life, Vodafone offers the opportunities to help you belong and make a real impact.

Role Purpose

To design a unified, scalable, and secure Data blueprint in conjunction with tech group to integrate scattered NW  and Business Data . This role ensures that all Data project is in align  business vision while maintaining a unified standard across all departments to avoid Data silos.

Role Profile

• Technology Stack Ownership and Alignment with Data Group Technology: Lead the evaluation and selection of all Data tools and ensure group approval for these tools (e.g., choosing the Data Virtualization tools, choosing the Cloud provider, or the Data Lake technology). Also Responsible for reporting  to the Group Architecture Maturity Index & initiating any project to meet it.
• Enterprise Data Transformation: Assess current and planned Architecture and identify Gaps towards a trusty data  and work on high-level design for these projects to ensure engagement of Business and Governance   – during the project, s/he will act as principal architect responsible for  ensuring that objectives, KPIs are going to be achieved
• Data Infrastructure Readiness for AI : Preparing the data foundation so that internal data scientists can safely use data in their models to learn. If Any discovered gaps, he should put roadmap to close.

•  Architectural Enablement for "Intelligent Data Apps" : The architect must ensure the data infrastructure perfectly supports “Intelligent Data SW products” that adds more analytical insights for Business  (IN & Out Data Flow ) and future proof Visualization tools.

• Business Alignment & Governance & Lifecycle Management: The architect ensures technology roadmap serves business demand and maintains the long-term health of the data ecosystem.

Responsibilities

Technology Stack Ownership and Alignment with Data Group Technology: 

• Negotiate with Group Architecture on yearly plan and budget
• Responsible for evaluating SOA and identifying Gaps to be Studied and budgeted for so that it can be implemented
• Cross-Domain Domain Modeling Alignment: Collaborate with group architecture to review data attributes across complex domains (e.g., Network Core, BSS/OSS, Retail transactions), ensuring schemas are optimized for high-performance processing inside your Intelligent Data Apps.

2.Enterprise Data Transformation

• Assess current and planned Architecture and identify Gaps towards a trusty data  and work on these projects till it is transferred from a GAP to project with initial study document with High level design/KPIs and budget – during the project, s/he will act as principal architect responsible for low level design and ensuring that objectives and KPIs are going to be achieved
  •  Introducing Advanced Data Virtualization strategies (e.g., Trino, Denodo) to sit on top of all data sources, to allow real-time, ensuring low-latency querying across  without moving raw data unnecessarily)
  • Data Lakehouse  Evolution: Serve as the Principal Architect for migrating the company’s legacy Big Data (Hadoop/On-Prem) estate to a modern, cloud/hybrid Data Lakehouse environment (e.g., Databricks, Snowflake, Delta Lake). Design the multi-phase migration roadmap, Focus on decoupling compute/storage separation and concurrency standards.
• Data Governance Integration: Architect automated hooks within the Lakehouse migration so that data metadata, schemas, and lineage are automatically captured by the governance framework at ingestion.

• DaaS Evolution: Review and expand the existing DaaS (API) infrastructure ( Document Blueprint for the underlying current/new architecture that exposes data assets via secure, high-speed APIs, allowing developers to query enterprise data)

3. Data Infrastructure Readiness for AI

Preparing the data foundation so that internal data scientists and external enterprise AI clients can safely consume your telecom data core.

• Semantic Layering for GenAI ("Chat with Data"): Architect the semantic data layer and Vector/Graph database integration guidelines. This allows LLM applications to securely map natural language queries directly to your mature DaaS APIs, grounding the AI and preventing data hallucinations.
• Data Architecture for Autonomous Agents: Design high-concurrency, immutable data snapshot patterns. This ensures that when multi-agent AI systems query network or commercial data simultaneously, they work from a consistent, synchronized state without causing database deadlocks or performance lags.
• AI Data-Sourcing & Feature Engineering Standards: Establish standardized, reusable data-delivery interfaces for  Data Scientists ensuring clean, governed telemetry is served with minimal latency.
• Next-Gen Visualization ("Chat with Data"): Explore, architect, and run Proof of Concepts (PoCs) for Generative AI/LLM integration (e.g., Retrieval-Augmented Generation / RAG architecture), enabling business managers to ask natural language questions directly to the data lakehouse

Responsibilities cont.

4. Architectural Enablement for "Intelligent Data Apps"

The architect must ensure the data infrastructure perfectly supports business-facing software products&  future AI tools.

• Architecting for Intelligent  Apps: Design the high-throughput, reusable data blueprints required to power complex internal software products (e.g., your retail mgmt. system, and Roaming Insights platforms). Ensure data flows seamlessly to support real-time calculations and predictive forecasting engines.
• Enterprise AI Readiness Assessment: Systematically audit the data estate to evaluate if the data is structurally ready for AI/ML. Define architectural prerequisites—such as feature stores and low-latency data pipelines—needed to support production-grade AI models in these intelligent Data Apps
• Next-Gen Visualization ("Chat with Data"): Enable this concept for internal developed Intelligent Data Apps by designing semantic layer

5. Business Alignment, Governance & Lifecycle Management

The architect ensures technology serves business demand and maintains the long-term health of the data ecosystem.

• Translating Business Demand to Tech Strategy: Act as a high-level internal consultant to commercial, digital, and network business units. Translate complex commercial goals into structural data requirements to ensure technology investments directly unlock business value.
• Architecture Review Board (ARB) Leadership: Act as a vital member of the Data ARB, reviewing and approving technical designs submitted by various business units to prevent the creation of new data silos.
• Legacy Decommissioning & Technical Debt Management: Author the architectural "sunsetting" roadmaps for legacy telecom data silos to reduce corporate infrastructure costs and manage technical debt during major platform cutovers.
• Act as Cross-Functional Orchestration & Guardrails for Data Organization:
  •  Ensure the standard macro-ingestion and integration patterns (e.g., real-time event streaming standards vs. batch window architectures).
  • Ensure Data Modeling is according to industry standard guidelines (aligning closely with TM Forum SID telecom models).
  • Partner with Governance to define architectural requirements for automated metadata cataloging, master data management (MDM) for entities like retail sales reps, and data lineage tracking.
  • Ensure compliance mandates (GDPR, local telecom privacy laws) and zero-trust security architecture requirements into the macro designs, ensuring sensitive commissioning and network data is strictly protected

Core Competencies and Qualifications

• Technical Expertise: Strong understanding of modern data architectures (e.g., Bigdata, DWH, AI  systems and  real-time data streaming), tools, and programming languages
• Leadership: Ability to inspire and align diverse teams, manage complex projects, and influence cross-functional stakeholders.
• Strategic Thinking: Capable of balancing short-term deliverables with long-term vision and scalability.
