Jobbeschreibung

Program Details

Location: On-site with the team in Berlin, Germany

Program length: Up to 12 months (full‑time, paid)

Start: April 2026

Cohort size: Limited (14 total across all tracks – Data Analyst, Software Engineer, ML Engineering, Data Scientist)

Target profiles: Final‑year students, recent graduates, early‑career (0–2 years)

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’s next‑gen AI tools turn 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 data scientists.

Your Impact And What You’ll Do

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

• Build end‑to‑end product features for SumUp – from backend APIs to user‑facing services (Web, Android, and iOS).
• Integrate with core SumUp systems, databases, and internal tooling.
• Write clean, testable, well‑documented code following team standards.
• Participate fully in team rituals: planning, technical discussions, code reviews, and knowledge‑sharing sessions.
• Learn and apply engineering best practices across software development, AI systems, and UI/UX design.
• Take ownership, iterate quickly on ideas and prototypes, and learn by shipping real features.

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 engineer with support to grow confidently.

You might be a great fit if you

• Are a recent graduate (Bachelor’s or Master’s), final‑year student, or early‑career professional (0–2 years’ experience) in Machine Learning, Data Science, Computer Science or related fields.
• Have an understanding of machine learning models (classification, regression, unsupervised learning, etc.) and statistics.
• Have hands‑on experience with Python and libraries such as pandas, numpy and scikit‑learn. Langchain or pydantic is a plus.
• Are familiar with LLM models and interested in evaluating methods (rubric‑based scoring, prompt‑based judges, calibration approaches, or human‑in‑the‑loop evaluation).
• Are familiar with Git and collaborative workflows (branches, pull requests).
• Have awareness of RDBMS concepts, can write simple SQL queries, and understand how data is structured and accessed.
• Write clean, functional code and actively seek feedback for improvement.
• Are curious about AI, data, and how technology creates real merchant value.
• Learn fast, welcome feedback, and enjoy working in collaborative cross‑functional teams.

We apply a consistent technical bar focused on fundamentals – not pedigree – and welcome candidates from a wide range of backgrounds.
