The Job
At Backbase, we don’t just deliver software – we redefine how people manage their finances. We are looking for a Senior Fullstack Engineer to join our R&D department in Kraków. You will join the team which sits at the core of Backbase platform: Entitlements. Handling complex problems related to Access Control, Approvals and Limits.
By joining our team, you won’t just write code; you will design systems that impact millions of users across over 100 financial institutions worldwide.

Meet the Job
As a Senior (P3) Engineer, you are a technical cornerstone of your squad. You will design and deliver complex features with minimal guidance, ensuring that both the "engine" (Backend) and the "experience" (Frontend) are performant, secure, and scalable.
  • Full SDLC Ownership: Lead the entire lifecycle of digital banking products—from initial idea and architectural design to release and maintenance.
  • Architectural Excellence: Improve system architecture and design components that integrate smoothly across APIs and microservices.
  • Technical Leadership: Act as a go-to resource for your team, mentoring junior engineers, conducting critical code reviews, and raising the bar for engineering standards.
  • AI & Innovation: Contribute to the evolution of LLM-based voice assistants and real-time personalization engines using OpenAI and ML models.
  • Security-First Mindset: Implement "Entitlements" and fraud prevention services with a focus on non-functional requirements like security, scalability, and resilience.
  • Collaborative Culture: Work in a Pod based model, collaborating with Architects, Product Owners, and UX Designers to align technical solutions with business needs.

Who You Are
  • Location: You live in Kraków or nearby area and you are willing to work in a hybrid mode - twice per week from our office. 
  • Experience: You have 5–7+ years of professional experience building complex, high-traffic products.
  • Backend Mastery: Solid understanding of Java, Spring JPA/Hibernate, and Maven. Experience with Microservices (Netflix OSS is a plus) and Cloud technologies.
  • Frontend Expertise: Strong skills in Angular and TypeScript. You are proficient with RxJS and modern build systems (Webpack, Jenkins). Experience with Vue.js is a plus.
  • System Design: You have a solid grasp of Enterprise Integration Patterns and can design systems that handle complex data flows between services.
  • The "Senior" Edge: You don't just solve tickets; you identify gaps in tooling, reduce technical debt, and optimize CI/CD pipelines to streamline delivery.
  • Communication: Excellent English (spoken and written). You can confidently explain technical concepts to non-technical stakeholders and get buy-in for your architectural decisions.
  • Domain Knowledge: Previous experience in Fintech or Banking is highly considered an advantage.
