At TechBiz Global, we are providing recruitment service to our TOP clients from our portfolio. We are currently seeking an Data Architect to join one of our clients ' teams. The Data Architect will design and govern the complete data ecosystem for the ValueX platform — including data ingestion, processing, modeling, storage, orchestration, and governance.
They will define the data architecture blueprint supporting the system’s core modules.
Customer Segmentation
ML/AI Model Management & Simulation Engine
The architect will ensure scalability to handle 50 million+ customer profiles, real-time event streams, and ML-driven decisioning — with a focus on performance, cost optimization, and maintainability.

Data Architecture & Design
Define the end-to-end data architecture across batch, streaming, and real-time layers.
Design Customer 360 and Offer 360 data models, including feature store and historical layers.
Establish logical, physical, and semantic data models to enable segmentation, scoring, and orchestration.
Define data contracts for Kafka topics, API payloads, and Adobe/CDP integrations.
Set up data versioning and lineage frameworks to track data provenance

Data Ingestion & Integration
Architect data ingestion pipelines from multiple telco sources: OCS, CRM, Kenan, Billing, DWH, Adobe AEP, Pricefx, and external APIs.
Standardize data access through APIs or data products for downstream modules.
S3, Delta Lake) and integration middleware (e.g., Data Management & Governance
Define and enforce data quality, lineage, catalog, and access policies.
Set up data validation and DQ frameworks (Great Expectations, Deequ).
Govern data partitioning, schema evolution, retention, and archiving strategies.
Ensure compliance with data privacy and regulatory standards (e.g., PDPA, GDPR, local telecom data policies).

Scalability, Cost & Performance
Design for high performance and cost-efficient scalability (25M → 50M → 75M customers).
Optimize compute/storage balance across environments (Dev, UAT, Prod).
Define data lakehouse optimization strategies (Z-Order, Delta caching, compaction).
Monitor and manage query performance, cluster sizing, and job orchestration costs.
Work closely with Data Engineers, Data Scientists, and Application Developers to ensure architectural alignment.
Lead architecture review boards and maintain data design documentation (ERD, flow diagrams, schema registry).
Serve as technical liaison between business stakeholders, data teams, and platform vendors (Databricks, Adobe, Pricefx).
Provide best practices and design patterns for model deployment, retraining, and data lifecycle management.
