Job Description

About the Opportunity

At N26, security is the foundation of our bank. We are looking for a Senior Full-stack Engineer to join our Security Engineering team. In this role, you will be part of a small, high-impact, and independent team responsible for building and scaling the N26 Security Platform. This team acts as a central force within our security organization, building the internal products and automation engines that support multiple specialized teams across the company. This is a role for an engineer who thrives on autonomy and wants to solve high-stakes technical challenges. You will have the independence to lead technical decisions and transform complex security requirements into elegant, scalable software that protects millions of users.

As a Full-Stack Engineer, you will be at the forefront of our GenAI and LLM initiatives, building the foundational architecture required to safeguard sensitive data and automate data governance. You won’t just identify AI risks - you’ll engineer the solutions to mitigate them. Beyond AI, you will develop and scale secure-by-design features across our entire stack, ensuring our ecosystem remains resilient. By building the solutions that power our Product Security Programs, you will enable our engineering teams to ship secure code faster than ever.

Once here you will

Design and Own End-to-End Solutions: Lead the architectural design and implementation of full-stack features, from robust backend services to intuitive internal dashboards.
Build the Security Platform: Develop tools and platforms that enable other security teams to automate threat detection, incident response, and vulnerability management at scale.
Enable the Organization: Act as a technical partner to various teams within the security department, building the shared infrastructure and automation they need to operate efficiently.
Drive Technical Excellence: Choose the right tools for the job, maintaining a high bar for code quality, automated testing, and system reliability.
Champion “You Build It, You Run It”: Own the full lifecycle of your services, leveraging modern CI/CD practices and infrastructure-as-code to ensure seamless production deployments.
Mentor & Influence: Share your full-stack expertise with the wider security organization, helping to foster a strong engineering culture within the department.

What you bring

Strong Full-Stack Foundation: 5+ years of experience building production-grade applications. You are a “solid” engineer who can navigate both backend architecture and frontend user experience with ease.
Technical Versatility: Deep proficiency in at least one backend language (Python, Go, or Java/Kotlin) and modern frontend frameworks (React is highly preferred).
Self-Driven Independence: A proven track record of working effectively in small, autonomous teams. You are comfortable taking a vague problem and turning it into a concrete technical solution without heavy oversight.
Cloud & Infrastructure Knowledge: Experience with AWS and containerization (Docker/Kubernetes).
Security Interest (as a plus): While your primary strength is engineering, a strong interest in the security domain or prior experience with security automation tools (SAST/DAST, SIEM, SOAR) is a significant advantage.
Quality Craftsmanship: A commitment to clean code, scalability, and building systems that are as secure as they are performant.

What’s in it for you:

Accelerate your career growth by joining one of Europe’s most talked about disruptors.
Employee benefits that range from a competitive personal development budget, work from home budget, discounts to fitness & wellness memberships, language apps and public transportation.
Come together with your team in the office for a dedicated day of teamwork each week, plus another day of your choice, and enjoy the flexibility of remote work the rest of the time. Some roles may require additional in-office presence.
As an N26 employee you will have access to a Premium subscription on your personal N26 bank account. As well as subscriptions for friends and family members.
Additional day of annual leave for each year of service.
A high degree of autonomy and access to cutting edge technologies - all while working with a friendly team of peers of diverse nationalities, life experiences and backgrounds.
A relocation package with visa support for those who need it.
