Backend Engineer – Core Systems

Bank Core runs the systems at the heart of N26 - accounts, ledgers, and the core banking logic every other team builds on. You'll shape decisions that reach across the entire company, working with real problems in a deep domain with direct impact.

What you'll do

• Own features end to end on systems that move real money for millions of customers
• Go deep on the banking domain - payments, ledgers, and the rules beneath them - and use that understanding to question and sharpen what we build
• Drive your own priorities within a cross-functional team, and unblock yourself when you hit a wall
• Raise problems early with a proposed solution, instead of working around them
• Ship incremental improvements and share your findings - including at our Get Stuff Done Days

What you'll need

• Solid grasp of microservice architecture
• Comfortable with relational databases, Postgres preferred
• Experience operating in a modern cloud environment, ideally AWS and Kubernetes
• Full professional proficiency in English
• 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 write well-tested code and treat security as part of the job, not an afterthought

Nice to have

• Event-driven systems with Kafka
• Payments, ledgers, or other banking/fintech domain experience

What they offer

• Competitive personal development budget, work from home budget, fitness & wellness memberships, language apps and public transportation
• Premium N26 bank account subscription and subscriptions for friends and family members
• Additional day of annual leave for each year of service
• Relocation package with visa support
