Senior AI Applied Software Engineer

At Backbase, we don’t just deliver software – we redefine how people manage their finances. We are looking for a Senior AI Applied Software Engineer to join the Onboarding & Origination value stream within the R&D department. You will focus on creating innovative, efficient, and adaptive solutions that streamline operations, enhance compliance, and drive superior performance for financial institutions. You will be working on building the customer experience path of exploring banking products and banking products management.

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.

As a Senior AI Applied Software 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 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.

• 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 Exposure: While the daily work is heavily backend-centric, prior exposure to Angular/TypeScript (RxJS) or Vue.js is a welcome bonus, offering a great foundation for future fullstack growth within the team.
• 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.
