Description du poste
SBS builds mission-critical banking software and, together with our sister company Axway, now forms the 74 Software group. Within our Digital Banking Business Unit, we are assembling a small, high-impact team to craft a new generative-AI product line.
Your first mission: design and deliver a retrieval-augmented-generation (RAG) platform that lets bankers compose and deploy their own AI agents—securely, compliantly, and at scale. You will be one of the founding AI engineers on this journey, shaping architecture, practices, and culture from day one.
Key Responsibilities
1. GenAI Architecture & Development
End-to-end design of RAG pipelines: document ingestion, chunking, embedding, vector search, prompt engineering, guards, and evaluation.
Integrate open-source and commercial LLMs (e.g., OpenAI, Gemini, Llama-3 etc.) via LangChain / LlamaIndex or custom frameworks.
Build reusable “agent primitives” so non-technical users can chain tools, memory, and policies into bespoke banking assistants.
2. Data & Domain Governance
Implement data-classification, masking, PII scrubbing, and hallucination mitigation aligned to EU banking regs (EBA, GDPR, DORA).
Collaborate with our Risk & Compliance team to embed explainability and audit trails in every response.
3. MLOps & Platform Engineering
Containerize and orchestrate AI micro-services on Kubernetes/OpenShift; automate CI/CD with GitLab.
Own model lifecycle: evaluation suites, continuous monitoring, rollback strategies, and cost optimisation.
4. Collaboration & Leadership
Mentor two junior engineers and evangelise best practices across the company.
Work closely with Product, UX, and Solution Architects to translate banking workflows into agent capabilities.
