Let’s build the future of mobile telecommunications together What Do We Expect From You As a Senior Data Architect within Product Architecture, you will address the critical challenge of a fragmented data model across our various teams. This pivotal role is responsible for unifying disparate data sources - including telemetry, service graphs, and Root Cause Analysis (RCA) inputs - into a single, coherent, and consistent data model. This foundational work is a prerequisite for advancing our capabilities in Generative AI, comprehensive observability, and robust service assurance, enabling a truly data-driven approach across our product portfolio. Responsibilities: Unified Data Model Design & Ownership: - Lead the architectural design and implementation of a unified data model that consolidates telemetry, service graphs, RCA, and other critical operational data. - Define conceptual, logical, and physical data models that support diverse product needs while ensuring consistency and interoperability. - Establish and maintain data architecture standards, principles, and best practices across the product organization. Data Integration & Pipeline Architecture: - Architect scalable and efficient data pipelines for ingesting, transforming, and harmonizing data from various heterogeneous sources. - Design robust data integration patterns (e.g., streaming, batch processing) to ensure data availability and freshness for downstream consumers. - Ensure data quality, integrity, and security throughout the data lifecycle. Enabling AI, Observability & Assurance: - Ensure the unified data model serves as a foundational prerequisite for GenAI applications, providing clean, contextualized data for training and inference. - Design data structures and access patterns that enhance observability capabilities, enabling real-time monitoring, analytics, and alerting. - Architect data solutions that power advanced service assurance functionalities, enabling accurate fault correlation, root cause analysis, and performance management. Data Governance & Lifecycle Management: - Collaborate with data governance teams to establish data ownership, definitions, and stewardship across product domains. - Define data retention policies, archiving strategies, and data lifecycle management processes. - Ensure compliance with data privacy regulations and security best practices. Technical Leadership & Collaboration - Provide senior technical leadership and guidance to engineering teams on data modelling, database technologies, and data architecture best practices. - Work closely with other architects (AIML, Observability, Workflow Management), data scientists, and product managers to understand data requirements and deliver impactful solutions. - Champion a data-first mindset and promote data literacy across the organization. Qualifications: - 10+ years of hands-on experience in data architecture, data modelling, and designing large-scale data platforms. - Proven track record of unifying fragmented data landscapes and building robust, scalable data models for complex domains. - Expertise in designing data solutions that support real-time analytics, observability, and machine learning applications. - Strong background in architecting data pipelines and integration strategies for high-volume, diverse data sources. Technical Skills - Deep expertise in relational, NoSQL databases (e.g., Cassandra, ClickHouse) and TSDB (e.g., Cortex, VictoriaMetrics, etc.) - Strong experience with stream processing technologies (e.g., Kafka, Flink, Spark Streaming) and batch processing (e.g., Apache Spark). - Proficient in data modelling techniques (dimensional, relational, graph) and data schema design. - Knowledge of data governance frameworks and tools. - Proficient in SQL and at least one relevant programming language. Domain Knowledge - Familiarity with telecom operational data, including network telemetry, service topology/graphs, and alarm/event data. Analytical and Problem-Solving Skills - Exceptional analytical skills to identify data relationships, inconsistencies, and design optimal data structures. - Strong problem-solving abilities for complex data integration and quality challenges. Collaboration & Communication - Excellent written and verbal communication skills, able to articulate complex data architectural concepts to technical and business stakeholders. - Proven ability to collaborate effectively with cross-functional teams, driving consensus on data standards. Educational Background - Bachelor’s degree in Computer Science, Data Science, Information Systems, or a related technical field.
