Your team and its impact

TAR-Billing executes pricing rules, bills customers and collects fees across Private Individuals, Business Banking and Wholesale Banking at ING Belgium. Our Customer Journey Experts, Technical Analysts and Developers also work with Finance and Tax on fee-related reporting.

As a provider team, we help products and segments evolve their billing—from new subscription packs to flexible campaign discounts and rewards. Our goal: clearer, more transparent fees and a better customer experience and Net Promoter Score (NPS).

We sit within the Daily Banking tribe, in the Onboarding Packs & Acquisition area, while serving all customer segments.

Your role

Understand and challenge business needs, advise from a billing perspective and turn them into precise business requirements for TAR Developers. Work with the IT Analyst, who owns the technical design. Your focus: rigorous analysis and changes that meet agreed needs.

What you will do

• Clarify and challenge needs. Advise product and segment teams on billing options and impacts on customers and processes.
• Define actionable requirements. Document current and target processes, business rules, exceptions and acceptance criteria. Assess solution options with the IT Analyst and Developers, using data to support analysis.
• Improve the colleague platform. Define business requirements and test changes to the platform ING colleagues use to consult and adjust fees.
• Identify dependencies. Align business and technical stakeholders, including Finance and Tax. Flag cross-project dependencies, especially when the Product Owner cannot investigate them directly.
• Validate delivery. Support backlog refinement, prepare and perform User Acceptance Testing (UAT), support releases and verify changes against agreed requirements. The Product Owner owns the project overview, backlog priorities and team planning.
• Own your analysis. Build billing expertise, challenge unnecessary complexity and follow through on open questions, progress, risks and decisions needed.

Deepen your pricing and billing expertise through cross-product analysis and hands-on delivery. Develop transferable skills in requirements, dependencies and stakeholder collaboration.

What you bring

You enjoy analytical depth, precise requirements and thorough follow-through. You bring structure to complexity and explain it clearly.

Essential requirements

• At least five years of relevant experience combining business and functional analysis, requirements ownership and delivery follow-up.
• Clear communication and stakeholder management. Explain complex topics simply and coordinate stakeholders and dependencies.
• Strong documentation skills. Produce concise business requirements, clear process flows and actionable functional requirements.
• Rigour and initiative. Check completeness and consistency, challenge assumptions and own follow-up. Work independently while staying aligned with the team.
• Technical fluency. Discuss system behaviour, data flows, interfaces and dependencies, bridging business and technology.
• Full professional proficiency in English, written and spoken. Independently lead discussions, write precise requirements and explain business and technical topics.

Additional assets — not prerequisites

• Experience in banking, particularly in pricing, billing or fee-related processes.
• Previous experience at ING.
• Knowledge of French or Dutch.

Meet the essentials? Apply even if you do not have every additional asset. Share examples of your requirements, process flows, technical collaboration and dependency management.
