About the Role

We are looking for an AI Engineer to join the Publicis Production AI team to build the next generation of AI-powered products and workflows for content and campaign creation. The role combines backend engineering with applied AI, focusing on designing and building scalable Python services and APIs, orchestrating large language models, and developing agentic and GenAI pipelines.

Responsibilities

  • Design, develop, and maintain scalable backend APIs and microservices in Python, primarily using FastAPI.
  • Build orchestration layers that connect and manage multiple Generative AI models and providers.
  • Design and implement agentic workflows using modern orchestration patterns.
  • Create innovative end-to-end GenAI pipelines for advertising and campaign creation.
  • Develop reusable AI components and services.
  • Integrate third-party AI APIs and SDKs.
  • Implement Retrieval-Augmented Generation (RAG), embeddings, vector search, structured data retrieval, and grounding approaches.
  • Evaluate models and prompting strategies for quality, latency, reliability, safety, and cost.
  • Build robust data-processing and asynchronous workflows.
  • Implement production engineering best practices including automated testing, API validation, error handling, logging, monitoring, tracing, rate limiting, caching, and performance optimization.
  • Deploy and operate AI services in cloud environments, primarily Azure and Google Cloud Platform (GCP).
  • Collaborate with frontend, platform, DevOps, product, and data teams.
  • Participate actively in agile product delivery through technical design, sprint planning, code reviews, pull requests, documentation, troubleshooting, and continuous improvement.
  • Stay current with rapidly evolving Generative AI technologies and identify opportunities for production features.

Requirements

  • Master’s degree in Computer Science, Engineering, Mathematics, Artificial Intelligence, or a related technical field, or equivalent practical experience.
  • Strong Python engineering skills and experience building production-quality backend applications or services.
  • Hands-on experience designing REST APIs, ideally with FastAPI.
  • Good understanding of software engineering principles including modular architecture, object-oriented and functional programming patterns, testing, maintainability, and code quality.
  • Practical understanding of Generative AI concepts including LLMs, agents, RAG, embeddings, structured outputs, tool/function calling, multimodal models, text-to-image, and diffusion-based generation.
  • Experience using APIs or SDKs from leading AI providers such as OpenAI, Gemini/Vertex AI, Claude, Adobe Firefly, or equivalent platforms.
  • Experience with agent or workflow orchestration frameworks such as LangGraph, LangChain, Semantic Kernel, or equivalent patterns is a strong advantage.
  • Familiarity with cloud platforms, preferably Azure or Google Cloud Platform (GCP).
  • Strong knowledge of Git and collaborative development practices including branching, pull requests, code reviews, and CI/CD workflows.
  • Ability to move comfortably between experimentation and production engineering.
  • Strong problem-solving skills, curiosity, and the ability to learn quickly.
  • Ability to collaborate effectively with engineers as well as product, design, creative, and production stakeholders in an international team.
