Senior Customer Success Manager

Ready to grow your CSM career in a fast-moving, creative industry?

As a Senior Customer Success Manager, you'll work directly with our most valuable customers, guiding them from first collaboration to long-term results. Your role is to make sure they get the most value from our (AI) technology, services and their partnership with our freelance network. You’ll focus on building long-term relationships, lead the execution of tailored solutions, and own retention and upsell opportunities. You’ll be working in a fast-growing segment of our business, and we’re looking for someone who can think creatively, act proactively, and thrive in a dynamic environment.

Welcome to Contentoo!

At Contentoo, we help businesses grow through exceptional content, scaling creation and localisation globally. We connect industry experts, talented creators, and translators with customers from a wide range of industries.

Do you excel in relationship-building, commercial strategy, and creative problem-solving? Join our fast-growing, Amsterdam-based scale-up and lead efforts that fuel business growth. We’re all about opportunities, positivity, and enjoying the journey. Use your experience to help brands deliver better content, faster.

What you’ll do

• Build strong working relationships with a set of high-value clients. Align their goals with Contentoo’s services, check in regularly, and solve issues before they grow.

• Work with teams across onboarding, talent, operations, and product to ensure smooth setup and collaboration between clients and freelance creators.

• Become an expert in Contentoo’s platform. Use it to improve the customer experience, find new opportunities, and help clients get the most from the tools.

• Keep your accounts healthy and growing by building relationships with multiple stakeholders in each company. Spot chances to expand into new teams or offer new services.

• Take ownership of your accounts. Lead renewals, spot upsell opportunities, run Executive Business Reviews, and create success plans that show long-term value.

• Support newer CSMs and help improve how the CS team works by sharing clear, actionable ideas with the Head of CS.

• Work with teams such as Finance, Marketing, and Legal to continually improve the overall customer experience.

What you’ll bring

• You are fluent in English, both verbally and in writing; Dutch is a bonus.

• You are a positive, proactive professional with at least 4 years of experience in a commercial, customer-facing, consulting, or partnership management role.

• You have a proven track record of managing high-revenue books of business and/or enterprise customers, and you’re comfortable building strong, trust-based relationships with senior stakeholders.

• You thrive in a fast-paced, evolving environment and are a true self-starter with a hands-on, commercial mindset. You’re not afraid to roll up your sleeves, think creatively, and make the most of the resources available to you.

• Your time-management skills and attention to detail are excellent, and you enjoy working on multiple projects simultaneously.

• You use AI to save time, find insights, and support your customers — and are curious about what’s next.

• You’re comfortable digging into data to understand customer behaviour and needs, and you have the basic analytical skills to translate insights into action.

• You combine a product mindset with hands-on platform knowledge — giving demos, supporting customers with confidence, and proactively suggesting product improvements to enhance the customer experience.

• A basic understanding of the content marketing landscape is preferred; bonus points if you’ve worked with or within a marketing team!
