Solution Architect

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.

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.

Define target-state architecture for modernising legacy billing platforms.

Lead architecture for legacy-to-cloud/native billing transformation .

Define migration strategies for customer, account, billing, usage, payment and historical data.

Assess build-vs-buy and product/platform options.

Identify opportunities to simplify legacy BSS landscapes and reduce integration complexity.

Strong Understanding of architecture across CRM, CPQ, Product Catalogue, Order Management, Billing, Mediation, Payment, Collections, ERP and OSS systems.

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.

Ensure loosely coupled and reusable integration architecture. TM Forum Open APIs are increasingly used to decouple BSS/OSS systems and support vendor-independent integration.

Strong telecom domain expertise

Deep billing and monetisation knowledge

End-to-end BSS understanding

Architecture and solution-design capability

Strong analytical and problem-solving skills

Excellent communication and stakeholder-management skills

Ability to work across business and technology teams

Strong vendor-management capability

Ability to simplify complex architecture

Ability to balance strategic architecture with practical implementation

The ideal candidate is not simply a billing application specialist .

They should be able to take a requirement such as:

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.

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.
