About the team:

Our Merchant Care team sits at the heart of SumUp's mission to empower small businesses. Our high-value merchant segment - businesses processing between €50K and €700K per month - needs more than reactive support. They need a proactive, trusted partner who understands their business and helps them grow. This role sits within a newly established, strategically important function that's scaling fast, with 10 new hires planned over the next three months alone. The UK is one of our largest and most strategic markets, and this person will play a central role in shaping how we serve it.

What you'll do:

• Take ownership of a portfolio of approximately 300 high-value merchant accounts, stepping in from month three of their journey with SumUp to drive long-term success
• Proactively engage merchants through calls, emails, and onsite visits - guiding them through product questions, supporting their growth plans, and conducting quarterly portfolio reviews
• Run personalised training sessions (remotely and onsite) to help merchants get the most out of SumUp's products
• Act as the bridge between merchants and internal teams - including product, sales, and support - to resolve issues and surface opportunities
• Monitor transactional data and account metrics to spot signs of churn early and take action before it becomes a problem
• Take a consultative approach to upselling and cross-selling, recommending products that genuinely fit the merchant's needs

You'll be great for this role if...

• Experience managing a portfolio of high-value or strategic accounts, ideally within SaaS, fintech, or payments
• Strong stakeholder management skills, with the ability to collaborate across sales, product, and operational teams
• A consultative, relationship-first approach to commercial conversations - focused on long-term value rather than aggressive sales
• Excellent communication skills in English, with the confidence to engage senior merchant contacts and internal leadership
• Comfort working autonomously across a busy portfolio, with strong operational problem-solving instincts
