Senior Full-Stack Security Automation Engineer

About the role

We are looking for a Senior Full-stack Engineer to join our Security Engineering 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. You will have the independence to lead technical decisions and transform complex security requirements into elegant, scalable software that protects millions of users.

What you'll do

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

What you'll need

• 5+ years of experience building production-grade applications across both backend architecture and frontend user experience.
• Deep proficiency in at least one backend language (Python, Go, or Java/Kotlin) and modern frontend frameworks (React is highly preferred).
• A proven track record of working effectively in small, autonomous teams, turning vague problems into concrete technical solutions without heavy oversight.
• Experience with AWS and containerization (Docker/Kubernetes).
• A commitment to clean code, scalability, and building systems that are as secure as they are performant.

Nice to have

• Strong interest in the security domain or prior experience with security automation tools (SAST/DAST, SIEM, SOAR).

What they offer

• Competitive personal development budget, work from home budget, fitness and wellness discounts, language apps, and public transportation discounts.
• Hybrid working: two days in-office per week, remote the rest of the time.
• Premium N26 bank account subscription, plus subscriptions for friends and family.
• Additional day of annual leave for each year of service.
• Relocation package with visa support for those who need it.
