Why This Role Matters:

Vonage is transforming its business support systems across lead-to-cash, billing, rating, customer identity, account management, data, analytics and platform services. This role provides the senior direction and momentum to simplify and modernize that landscape - ensuring platform decisions support scale, resilience, commercial growth and customer experience.

Key Responsibilities:

-

- Define and own the BSS transformation roadmap, aligned to Vonage's commercial, operational and customer experience ambitions

- Translate business needs across lead-to-cash, billing, rating, identity, account management, data and platform services into clear priorities and design principles

Governance & Change Management:

-

- Establish and lead transformation of governance, controls and decision-making mechanisms to keep execution aligned with approved strategy, scope, roadmap, and architecture

- Ensure a clear separation between transformation and BAU, while maintaining strong connectivity with operational teams on migration, adoption and change impacts.

Legacy Scope Management:

-

- Partner with the Sr.



Director of BSS to ground the roadmap in the current-state landscape and enforce a firm boundary preventing net-new functionality being added to legacy systems - minimizing the delta the programme must close.

Budget & Risk:

-

- Own the transformation budget: forecasting, spend tracking, and ensuring investment decisions are aligned to priorities and business value

- Own risk identification, mitigation planning and escalation, ensuring risks are visible, assigned, and actively managed across workstreams.

Stakeholder & Senior Leadership

-

- Partner with Product, Engineering, Architecture, Operations, Finance, Sales and Commercial teams to align scope, sequencing, dependencies and delivery outcomes

- Act as the senior business and product voice for the transformation, connecting platform decisions to commercial impact, operational efficiency and customer value.

- Lead vendor evaluation including RFPs/RFIs, evaluation criteria, response coordination and structured selection aligned to transformation objectives

- Drive measurable, time-boxed validation of vendor capabilities, integration feasibility and technical fit before platform commitments are made, ensuring decisions are evidence-based.

Process Transformation:

-

- Work with stakeholders across functions to identify,



document and roll out end-to-end process changes required to support future-state BSS capabilities.

What You'll Bring:

Required:

-

- Senior experience leading large-scale BSS, OSS, lead-to-cash, billing, rating, CRM, identity or platform-services transformation programmes

- Ability to shape strategy, establish governance, align senior stakeholders, and turn ambiguous needs into clear priorities

- Hands-on experience in end-to-end business process transformation and re-engineering across multiple stakeholder groups, including change and adoption of ownership

- Strong understanding of enterprise SaaS and back-office systems: CRM, billing, rating, analytics, identity, APIs and integration architecture

- Proven ability to make trade-offs across scope, sequencing, investment, risk, technical debt and business value

- Credible with senior technical, product, commercial and operational stakeholders; able to influence without direct line authority.

Nice to Have:

-

- Background in telecoms, CPaaS, UCaaS, SaaS or other high-volume transactional technology environments

- Experience with systems migration, platform consolidation, acquisition integration or business process re-engineering

- Familiarity with scaled agile delivery, product operating models, transformation governance, data models, APIs and integration patterns.
