Build AI-powered products that impact millions of small businesses - at the start of your career.

At SumUp, we build fintech solutions that empower over 4 million merchants across 37 markets to run and grow their businesses. Every day, this generates rich payments and business data - and SumUp Edge our strategic AI-initiative turns that data into practical insights and intelligent tools that create real merchant value.

The SumUp Accelerator is a two-part, up to 12-month, full-time, paid Program for early-career engineers who want to learn fast by working on real production systems.

This is not a traditional internship. From day one, you’ll join a product squad, contribute to shared codebases, and ship production code used by merchants every day - with guidance from experienced product analysts.

Your Impact and What You’ll Do

As part of an Edge squad, you’ll work alongside experienced engineers, data scientists, and product managers to:

• Analyse large-scale merchant-specific data sets to uncover insights and opportunities and create visualisations to understand product features, user behavior, and product performance.
• Write and execute SQL queries to extract and analyze product data from multiple sources to support business decisions and shape the product roadmap.
• Collaborate with product managers to define success metrics to measure the product's performance.
• Assist in building and maintaining dashboards to track product KPIs and feature adoption.
• Help document product metrics, data models, and analytical processes.
• Collaborate with product managers and engineers on product-related analytical tasks.

Your work will directly shape how millions of small businesses operate.

Mentorship, Growth & Career Path

The Accelerator is designed for fast learning and real impact, preparing you with the skills and experience needed to succeed in a long-term role at SumUp.

• Primary mentor for every participant
• Weekly check-ins focused on delivery, feedback, and growth
• Hands-on learning through real production challenges, not simulations
• Work as a full contributing analyst with support to grow confidently
