Principal Solution Architect

The job in short

As a Principal Solutions Architect at Backbase, you help banks integrate BankingOS with their existing technology and build solutions for Digital Banking and Agentic Banking.

You combine architecture expertise with hands-on development. You work with AI models, agent frameworks, APIs and integrations to build prototypes, test ideas and understand what works in practice.

You work alongside Solutions Engineers to design the overall architecture, connecting BankingOS with the bank's systems, data and security requirements. You explain technical decisions to executives, architects and engineers, and adjust your approach based on testing and evidence.

This is a senior individual contributor role focused on technical design, practical experimentation and mentoring colleagues. You also contribute to product improvements and develop reusable architecture patterns.
