Key Responsibilities

• HLD/LLD design, execution, integration design and delivery within the telecom domain.
• Convert high‑level architecture into detailed LLD artifacts, including integration flows, sequence diagrams, interface specifications and data mappings for clarity to development and testing teams.
• Design and document API integrations (REST, SOAP), system‑to‑system data flows, and integration patterns (event‑driven, batch, synchronous, asynchronous). Support integration across telecom systems such as CRM, Order Management, Billing, Usage, OSS and Inventory platforms.
• Work across one or more telecom areas: Wireless usage, CDR billing flows, inventory provisioning systems; apply understanding of OSS/BSS interactions and end‑to‑end service lifecycle (order, usage, billing).
• Design and document error handling, retry mechanisms, data validation and reconciliation approaches to ensure reliability of integration flows.
