About the opportunity Bank Core runs the systems at the heart of N26 - accounts, ledgers, and the core banking logic every other team builds on. We're revamping that core right now, so the engineers who join today shape decisions that reach across the entire company. Our services are written almost exclusively in Kotlin on Spring Boot, deployed on Kubernetes, communicating over Kafka, backed by Postgres, and running on AWS.
We lean heavily on agentic coding and expect you to do the same - but you stay in charge. Go deep on the banking domain - payments, ledgers, and the rules beneath them - and use that understanding to question and sharpen what we build
Comfortable with relational databases, Postgres preferred
Experience operating in a modern cloud environment, ideally AWS and Kubernetes
Full professional proficiency in English
Event-driven systems with Kafka
Payments, ledgers, or other banking/fintech domain experience
Relentlessly curious - you want to learn new domains like payments, ledgers, and banking from the ground up




Product-driven - you understand what you're building and push back when it doesn't add up
You surface issues early and bring solutions, never quietly route around them
You write well-tested code and treat security as part of the job, not an afterthought
What's in it for you:
Employee benefits that range from a competitive personal development budget, work from home budget, discounts to fitness & wellness memberships, language apps and public transportation.
As an N26 employee you will have access to a Premium subscription on your personal N26 bank account. A relocation package with visa support for those who need it.
N26 has reimagined banking for today's digital world. Technology and design empower everything we do and it's how we are building the integral banking platform the world loves to use.
We've eliminated physical branches, paperwork, and hidden fees for an elegant digital experience and supreme savings. Giving people the power to live
