Telecom Billing & BSS Architect
Experience: 10–15 years
Location: Hyderabad
Function: Technology – IT Delivery
Role: Telecom Billing Solution Architect
Role Overview
We are looking for an experienced Telecom Billing Solution Architect with 10–15 years of strong experience in telecom billing, charging, rating and BSS transformation.
The role will be responsible for defining end-to-end billing and BSS architecture, translating business requirements into scalable technology solutions, and driving architecture across customer, product, order, charging, billing, payment, collections and revenue-management domains.
The candidate should have strong telecom domain knowledge and the ability to work across business, product, technology and implementation teams in a complex multi-vendor environment.
Key Responsibilities
1. Billing Architecture
Own the end-to-end architecture for telecom charging, rating, billing and invoicing.
Design solutions covering:
Online and offline charging

Convergent billing
Prepaid/postpaid billing
Account and bill-cycle management
Payments and adjustments
Collections and dunning
Partner/interconnect billing and settlement
Design scalable solutions capable of supporting high-volume transaction and billing workloads.
Define billing architecture for B2C, B2B and enterprise customers.
2. End-to-End BSS Architecture Knowledge
Understanding of the complete Lead-to-Cash / Order-to-Cash journey across:
Customer → Product Catalogue → CPQ → Order Management → Provisioning → Usage → Mediation → Charging/Rating → Billing → Payment → Collections → Revenue Assurance
Ensure seamless integration between BSS and OSS platforms.
3. Product & Catalogue Architecture Knowledge
Understanding for enterprise product catalogue and commercial offer management Architecture.
Ensure consistent product, pricing and charging models across BSS platforms.
Support rapid introduction of new products, bundles, promotions and monetisation models.

Strong understanding of REST APIs, event-driven architecture, Kafka/message brokers, ESB/API gateways and microservices.
Apply TM Forum Open APIs where appropriate, particularly APIs around Product, Customer, Order and Billing management.

and independently define how the requirement flows through:
Product Catalogue → CPQ → Order Management → Customer/Account → Provisioning → Mediation → Rating → Charging → Billing → Invoice → Payment → Collections → Revenue Assurance
while defining the APIs, events, data flows, system responsibilities and integration architecture.
Key Success Measures
Successful delivery of scalable telecom billing architecture.
Reduction in billing defects and revenue leakage.
Improved time-to-market for new products and tariff plans.
Reduction of legacy platform dependencies.
Improved integration standardisation and API reuse.
