- Architect end-to-end solutions spanning customer/account management, pricing, rating, billing, invoicing, receivables, collections and payments.

- Design solutions across a complex enterprise ecosystem including ORMB, Oracle Fusion, CPQ, CRM, Product Master, tax platforms, integration services and enterprise data platforms.

- Lead resolution of complex cross-product, cross-squad and integration dependencies, particularly where issues span multiple systems or ownership boundaries.

- Remain hands-on and support teams in diagnosing and resolving difficult technical, data, performance and production issues.

- Define reusable engineering and integration patterns that improve scalability, resilience, observability and maintainability.

- Provide technical coaching, design reviews and hands-on guidance to engineers, raising engineering standards and building internal capability.

- Partner with Product, Architecture, Platform and Engineering teams to translate business outcomes into pragmatic, scalable technical solutions.

- Ensure technical solutions meet appropriate standards for security, resilience, performance, auditability, reconciliation and operational readiness.

**Experience & Skills:**

- Significant experience designing and engineering large-scale Billing and Order-to-Cash solutions.

- Deep hands-on expertise in Oracle Revenue Management and Billing (ORMB).

- Strong understanding of Order-to-Cash processes including pricing, usage/rating, billing, invoicing, receivables, collections, payments, adjustments and rebilling.

- Strong software engineering background, ideally including Java, Groovy, SQL and API development.

- Strong experience with application data modelling, REST APIs, event-driven integration and enterprise integration patterns.

- Experience integrating billing platforms with systems such as Oracle Fusion, CRM, CPQ, tax engines and enterprise data platforms.

- Strong understanding of scalability, performance, resilience, security, observability and recoverability for business-critical financial systems.

- Proven ability to solve complex end-to-end technical problems and influence architecture across multiple engineering teams.

- Strong technical leadership and mentoring skills, with the ability to raise capability through hands-on coaching rather than formal authority.
