SBS is headquartered in Paris, France.

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.

Key Qualifications & Skills

Technical Expertise - must-have :

• Programming: Python (advanced); TypeScript/Java is a plus.

• LLM Tooling: LangChain or LlamaIndex; prompt engineering; vector databases (PGVector, Weaviate, Milvus, Elastic, Pinecone).

• Cloud & Containers: Kubernetes/OpenShift, Docker, Terraform; at least one major cloud (Azure preferred, AWS/GCP fine).

• Data Engineering: ETL on structured & unstructured data, streaming (Kafka/PubSub), SQL optimisation.

• MLOps: CI/CD for models, experiment tracking (MLflow/Weights & Biases), monitoring (Prometheus/Grafana).

• Security & Compliance: OAuth2/OIDC (Keycloak), RBAC, secrets management, encryption in transit & at rest; familiarity with banking regulations.

Technical Expertise - nice-to-have

• Retrieval algorithms beyond dense vectors (hybrid BM25 + embeddings).

• Experience rolling out AI chat/agent products to external customers.

• Knowledge of EU or MEA banking standards

Experience & Work Ethic:

• 5 + years in software or data engineering with 2 + years hands-on GenAI / NLP.

• Proven ability to take fuzzy product ideas to production with minimal supervision.

• Strong communication skills; comfortable presenting technical trade-offs to non-technical stakeholders.

Why Join Us?

• Green-field GenAI stack: no tech debt-start with the latest research and tools.

• Real-world impact: empower banks to launch compliant AI services their customers can trust.

• Ownership & growth: shape the engineering culture inside a global group while staying in a tight, startup-like squad.

• Hybrid work & Paris HQ: flexible policy with regular on-site workshops for deep collaboration.
