Want to make a real difference for subscription businesses around the world? Come join us!

The role:

You will own a portfolio of our largest and most complex accounts, typically listed companies with mature finance teams and multi-entity setups. These customers expect a commercial partner who understands their business, not an account administrator. You build relationships across CFOs, RevOps leaders, and finance operations, anchor every conversation to measurable outcomes, and drive retention and expansion through structured commercial work.

This is a commercial role with commercial targets. You carry responsibility for net revenue retention on your portfolio, own your renewal and expansion pipeline end to end, and are measured on the outcomes. Beyond your own accounts, you support renewals across the wider customer base, bringing negotiation strength and commercial judgment where it matters most.

What you'll be doing:

• Own a portfolio of enterprise accounts with full commercial responsibility: retention, expansion, and net revenue retention on your book

• Build and execute account plans with a defined next commercial moment for every strategic account, backed by champion maps and multi-threaded relationships from CFO to RevOps

• Lead business reviews that connect Younium to the customer's outcomes: integrated quote-to-cash, accurate financial KPIs, controlled revenue leakage, automated billing

• Lead contract renewal negotiations on your own accounts and support renewals across the wider portfolio: prepare positions, handle objections with structure, protect price, and know when to hold rather than discount

• Identify, create, and close upsell and cross-sell opportunities, with CPQ as a core expansion motion, from first consultative conversation through demo to closed deal

• Maintain an accurate pipeline and forecast in HubSpot and own your numbers in pipeline reviews

• Monitor account health, manage risk proactively, and build success plans for at-risk accounts

• Coordinate with Product, Engineering, Professional Services, and Support to align priorities with customer expectations, and act as escalation point when it counts

• Channel structured customer feedback into product and commercial decisions

• Share commercial best practices and coach less experienced CSMs on the team

Who are you?

• 8+ years in customer success, account management, or a similar commercial role in B2B SaaS, with experience across both enterprise and mid-market accounts

• A proven commercial track record you can show in numbers: renewals closed, expansion revenue generated, retention targets hit

• Negotiation experience on contracts with real money at stake, comfortable defending price and terms with procurement and C-level stakeholders

• Proven stakeholder management at C-level, comfortable leading strategic conversations with CFOs and senior finance leaders

• Experience navigating complex organizations with multiple entities, stakeholders, and competing priorities

• Understanding of subscription business models and finance processes: invoicing, revenue recognition, ARR/NRR metrics. Experience with billing, CPQ, or ERP platforms is a strong plus

• A diagnostic approach: you ask questions, quantify pain, and anchor to outcomes before proposing anything

• Excellent written and verbal communication in professional English. Dutch, German, or a Nordic language is a plus

• Comfort working across European time zones with occasional travel
