    • Hybrid
      • Utrecht, Utrecht, Netherlands
    • Operations

    Own enterprise customers post-sales, drive long-term value and expansion, and play a key role in shaping Customer Success at a fast-growing B2B SaaS company.

    Job description

    The role

    CostPerform is looking for a Senior Customer Success Manager who will play a key role in ensuring long-term customer success while helping professionalise and evolve our post-sales organisation.

    This is not a narrow or purely operational CSM role. You will operate at the intersection of customer relationships, implementation, commercial growth and internal improvement initiatives. The role suits someone who enjoys ownership, context-switching, and bringing structure to an environment that is growing in maturity.

    CostPerform is a financially stable SaaS company with a long track record. We are entering a next phase where scalability, data-driven decision-making and post-sales excellence become increasingly important — without the chaos or pressure of a startup.

    What you’ll be doing

    Customer ownership & relationship management

    • Take over accounts after sales handover and own the long-term relationship

    • Build strong, trust-based relationships with senior stakeholders

    • Act as the primary point of contact for strategic and functional topics

    • Ensure customers feel supported, understood, and challenged where needed

    Value, adoption & retention

    • Drive adoption of the platform across use cases and teams

    • Help customers translate CostPerform insights into real business decisions

    • Reduce churn by embedding the product deeply into customer processes

    • Identify underused features and opportunities to increase value

    Upsell & expansion (value-driven)

    • Identify and develop upsell opportunities based on customer needs

    • Work closely with Sales on expansion opportunities and timing

    • Contribute to revenue growth without “hard-selling”

    • Balance commercial responsibility with long-term customer trust

    Internal collaboration & structure

    • Work closely with Sales, Product, Support, and our Implementation partners

    • Help professionalise handovers, account rhythms, and HubSpot hygiene

    • Contribute to clearer processes, dashboards, and customer segmentation

    • Act as a senior sparring partner within the Customer Success team

    Job requirements

    Who we’re looking for

    We’re looking for a senior Customer Success professional who enjoys complexity, ownership, and long-term customer relationships.

    You likely bring:

    • Proven experience working with complex, enterprise-level customers and multiple stakeholders

    • Strong communication skills — you can read the room, lead conversations and bring clarity when things get tense

    • Comfortable operating in an environment where roles are still evolving and where you can introduce constructive friction

    • Data-savvy and process-minded; experience with CRM and CS tooling (HubSpot is a strong plus)

    • Affinity with finance, consultancy or data-heavy software is a plus, not a requirement

    • Excellent English (near-native); experience with US customers is a strong advantage

    You are:

    • A Customer Success professional who chose this path deliberately

    • Comfortable combining relationship management with commercial responsibility

    • Structured and disciplined, but pragmatic in execution

    • Confident, calm, and able to bring stability to a growing team

    • Curious and capable of learning a complex product and domain

    What we offer

    • A senior, high-impact Customer Success role

    • Ownership of complex, enterprise-level customer relationships

    • Influence on how Customer Success is shaped and scaled

    • Hybrid working model

    • Competitive salary with performance-based upside

    • Non-contributory pension plan and full travel reimbursement.

    • A pragmatic, ambitious, and collaborative culture
