Your Role

As Senior Full Stack AI Engineer at Bank J. Safra Sarasin within our Artificial Intelligence Department, you are a technical backbone of a strategic legacy transformation program. You will design and build modern, high-quality software that replaces long-standing core banking applications - leveraging the bank's internal AI ecosystem and AI-powered development practices to deliver faster, safer and smarter.

You will join our newly established Artificial Intelligence Department and contribute to a strategic, multi-year legacy transformation program that modernizes core banking processes for our private banking business. You will be part of the AI team, leverage the bank's internal AI knowledge, tools and private-LLM ecosystem, and use AI to power your day-to-day work - while the focus of the role is on delivering the transformation, not on building AI products.

Your Responsibilities

• Design and implement production-grade features on a modern anchor stack
• Rebuild complex functional modules month-by-month with progressive cutover, working in one focused senior team
• Move business rules from compiled legacy code into a central, configuration-driven rule store
• Use AI-powered engineering daily - AI pair-programming, AI-assisted code analysis and modernization, AI-generated tests and documentation - leveraging the bank's internal AI knowledge, tools and private-LLM environment
• Integrate the new platform with surrounding core banking systems and third-party solutions
• Contribute to architecture decisions, CI/CD pipelines and coding standards, and join the process-redesign workshops that define what we build

Your Profile

• University degree in Computer Science, Software Engineering, or a related field
• Minimum 7 years of experience in full-stack software development, including delivery in complex, regulated environments (Finance, Insurance, or Healthcare)
• Expert-level proficiency in Java (ideally Quarkus or Spring Boot) and modern TypeScript/React
• Strong experience with relational databases, SQL, and database migration tooling
• Hands-on experience with Docker, Kubernetes/OpenShift, CI/CD (Azure DevOps or similar) and cloud-native architecture
• Practical experience using AI coding assistants and LLM-based tooling in the software development lifecycle; interest in agentic workflows and RAG is a strong plus
• Comfortable modernizing legacy systems - reading large codebases, reverse-engineering behavior, and writing the tests that were never there
• Fluency in English; other languages are an advantage

Your Benefits

• Entrepreneurial spirit in a family owned bank
• Central city office locations across Switzerland
• Above average insurance coverage fully borne by the bank
• Contribution to health insurance and meal allowance
• Global growth strategy and stable environment
• Competitive offering
