Senior Full-Stack Security Automation Engineer

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.

• 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.

• 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.

• Accelerate your career growth by joining one of Europe’s most talked about disruptors.
