## About the Role

* Education: Bachelor's degree or equivalent experience in Computer Science, Engineering, or a related field
 * Experience: Proven track record of building software products, backend systems, platform services, or cloud-native applications; experience in internal platform teams, product engineering, or data-driven application development is a strong plus
 * Technical skills: Strong command of Docker, Kubernetes/OpenShift, Python (FastAPI), Terraform, React, Node.js, and TypeScript; familiarity with AWS services (Lambda, API Gateway, ECS, RDS, Bedrock), Snowflake, PostgreSQL, Redis, message brokering, CI/CD (GitHub Actions), and GenAI/LLM application patterns is a meaningful advantage
 * Mindset: Versatile and adaptable, with a strong ownership mentality and service-oriented approach; comfortable working across multiple products simultaneously and thriving in ambiguous, fast-moving environments
 * Collaboration: Excellent communicator in English who can translate complex technical concepts for non-technical stakeholders and enjoys working across diverse, cross-functional teams

## Description

* Build full-stack applications and platform services across the OneMesh ecosystem using React, TypeScript, Node.js, and Python (FastAPI) - from data platform UIs and internal developer tools to AI-powered applications and operational dashboards
 * Design and maintain robust APIs (REST and GraphQL) that enable internal teams to discover, manage, and interact with data and AI capabilities, integrating cleanly into broader Sanofi digital products
 * Implement AI and GenAI application patterns including LLM APIs, Retrieval-Augmented Generation (RAG), agent orchestration, and evaluation frameworks, building reusable platform primitives that help other teams build faster and safer
 * Deploy and operate cloud-native applications on OpenShift (Kubernetes) and AWS, following GitOps best practices and contributing to infrastructure-as-code using Terraform
 * Champion production-readiness and observability by implementing security controls, audit logging, health checks, metrics dashboards, and alerting to ensure platform services are reliable, debuggable, and operationally sound
 * Build and maintain CI/CD pipelines to enable fast, reliable, and automated delivery, while contributing to code reviews, architectural discussions, and engineering standards
 * Collaborate across cross-functional teams - partnering with data engineers, ML practitioners, product teams, and business stakeholders to translate platform capabilities into polished, user-friendly features
