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
  • Usage rating and mediation

  • Discounts, promotions and bundles
  • Convergent billing
  • Prepaid/postpaid billing
  • Account and bill-cycle management
  • Payments and adjustments

  • 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

The role should understand the business journey and system interactions, not merely the billing application itself. Contemporary BSS architecture roles commonly cover CRM, order management, billing, mediation, provisioning, collections, customer care and Lead-to-Cash.

Preferred Product Experience

Experience with one or more telecom BSS/billing platforms such as:

• Kenan
• Amdocs
• Netcracker

• CSG
• Ericsson Charging/BSS
• Nokia BSS
• SAP BRIM
• Optiva

• 10–15 years of overall IT/telecom experience.
• At least 7–10 years of significant experience in telecom billing/BSS.
• Proven experience in solution architecture for large telecom transformation programmes.

Ideal Candidate Profile

The ideal candidate is not simply a billing application specialist.

They should be able to take a requirement such as:

"Introduce a new B2B telecom product with usage-based charging, discounts, recurring billing and partner settlement"

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.
• Successful migration to modern/cloud-native BSS platforms.
• Architecture compliance across programmes and vendors.
• Improved billing performance, reliability and operational efficiency.
