Job Description

Join our Payments Team and help shape secure, scalable payment experiences used by millions of customers every day. This is a high-impact engineering role at the centre of the customer journey, where performance, reliability, and user experience truly matter.

We’re looking for an experienced engineer who enjoys solving complex problems, collaborating across teams, and building modern applications at scale. While this is a full stack role, we welcome candidates with either stronger backend or frontend experience who are excited to work across the stack.

What You’ll Do

  • Build and evolve scalable payment solutions within a microservices environment
  • Take ownership of features from idea to production
  • Contribute to architecture and technical decision-making
  • Partner closely with product, engineering, and platform teams
  • Improve performance, reliability, and developer experience
  • Write clean, maintainable, and well-tested code

How We Work

  • Agile, collaborative teams with high ownership
  • “You build it, you run it” mindset
  • Code reviews, and knowledge sharing
  • Continuous improvement in both technology and ways of working

Tech Stack: Java 17+, Spring Boot, React, TypeScript, AWS, Docker, Kubernetes, Terraform, PostgreSQL, Oracle, Jenkins, Prometheus, Grafana, ELK

Qualifications

What You Bring

  • Experience building modern software applications at scale
  • Good knowledge of Java and Spring-based development
  • Experience with frontend technologies such as React and TypeScript
  • Familiarity with cloud platforms, CI/CD, and distributed systems
  • Passion for clean architecture and quality engineering practices
  • Collaborative mindset with a sense of ownership and curiosity

Nice to Have

  • Experience in payments or e-commerce environments
  • Exposure to observability and monitoring tools
  • Interest in AI-assisted development tools such as GitHub Copilot

Don’t meet every requirement? We’d still love to hear from you. We value potential, mindset, and engineering fundamentals as much as direct experience.

Additional Information

Headquartered in Munich, with offices across Madrid, Krakow, Wroclaw, London and Vienna, we collaborate because we genuinely love working together - so you’ll be at the heart of an incredible, multinational team. We trust each other to get the job done, which means you’ll benefit from hybrid working, spending 60% of your time in the office and 40% at home. There’s an option to work for 20 days abroad in approved countries too.

Add to that development opportunities that help you to shape your own career path, excellent training and support, wellbeing offers, subsidised transport or bike leasing, plus 20% discount across all our products, and you’ll begin to get a sense of what sets us apart.
