What tasks await you?

Position Overview

We are looking for a Data Architect to lead the data engine behind our Seamless Network Integration (SNI) vision—becoming the global leader in IoT network aggregation. In this role, you will build a unified data platform on Microsoft Fabric by harmonizing SIM and network telemetry across our own portfolio and partner MNO networks. To achieve this, you will migrate ~50 TB of legacy Oracle/SAP SIM data into Fabric, build adaptors into external Connectivity Management Platforms (CMPs), and deliver secure partner-portal analytics while designing the foundation for future real-time streaming (Kafka) and AI capabilities.

Key Responsibilities

• Design the target Microsoft Fabric state (Lakehouse, Pipelines, Notebooks, Direct Lake, Semantic Layer) to migrate ~50 TB of legacy Oracle SIM data and unify Seamless Network Integration data while managing cost, performance, and data residency.
• Build scalable ingestion pipelines (Oracle, CSV, CDC) and CMP adaptors to process high-volume SNI data, structuring it via Medallion Architecture (Bronze/Silver/Gold) and Star Schema models.
• Implement audience-tailored reporting for internal teams and partner portals to deliver real-time data insights using Power BI Apps and Embedded patterns.
• Work with development, QA, and DevOps teams through implementation and CI/CD setup.

What skills will be appreciated?

Hard Skills

· Deep technical experience with the Azure Data Stack (Databricks, Synapse, Power BI) with a strong focus on or transition to Microsoft Fabric (Lakehouse, Pipelines, Semantic Models).

· Python, PySpark, and large-scale extraction/migration of SIM and network telemetry (Oracle DB >10 TB, batch/CDC, flat files).

· Medallion Architecture, Delta Lake, and Dimensional Modeling (Star Schema) optimized for network and SIM data.

· Entra ID, Keycloak / OAuth2, Azure Key Vault, and Azure networking (Data Gateways, Private Endpoints).

· Granular data security (RLS/OLS), Fabric Git integration, and Azure DevOps CI/CD.

Preferred (Nice-to-Have)

· Hands-on experience with real-time streaming concepts (Apache Kafka, Fabric Eventstream).

· Background in Data Governance (Microsoft Purview), CMP integrations, or legacy SAP BODS replacement.

· Certifications: DP-600, DP-203, or AZ-305.
