We are looking for a Senior Agentic AI Engineer to join a high-performing creative innovation team within the Enterprise Marketing function of a global technology leader.

As the first hire of this kind within a newly established creative production model, you will be responsible for building the AI-powered infrastructure, automated workflows, and custom tools that enable the rapid creation and scaling of paid media assets across EMEA.

This is a hands-on engineering role focused on designing agentic systems, MCP integrations, and intelligent automation that connect creative workflows, design systems, content repositories, and performance data into a seamless production ecosystem.

Key Responsibilities

  • Design, build, and deploy agentic workflows and custom internal tools utilizing Anthropic Claude, OpenAI, and API ecosystems to automate the generation of static and video ad assets.
  • Architect and manage Model Context Protocol (MCP) Servers and configurations, establishing secure, standardized connections between LLM applications and our external tools, data sources, and asset repositories.
  • Develop and maintain the technical plumbing and API integrations connecting performance data pipelines, media libraries, and production software.
  • Engineer advanced context and prompt frameworks, utilizing MCP and other tooling to ensure context such as brand guidelines, design specs, program specific data sources are accessible and agent-readable.
  • Build automated agents capable of reading design systems, parsing creative template libraries, and outputting production-ready static and video assets.
  • Support the operational growth of the studio by architecting automated QA/QC and performance reporting tools.
  • Collaborate closely with the Creative Strategist and Designers to translate creative hypotheses and workflow bottlenecks into technical code requirements.
  • Maintain clean, documented code for all internal tools, agents, and custom integrations, ensuring workflows are stable, repeatable, and easily scalable across the region.

Skills & Experience

  • Proven experience building AI agents, agentic workflows, and multi-agent systems using tools such as LangChain, CrewAI, StackAI, or similar frameworks.
  • Strong experience with Anthropic Claude, OpenAI APIs, RAG architectures, and vector databases (Pinecone, Chroma, etc.).
  • Hands-on experience with Model Context Protocol (MCP).
  • Strong software engineering background in Python and JavaScript/Node.js.
  • Extensive experience designing and integrating REST APIs.
  • Solid understanding of prompt engineering, context engineering, and structured data formats such as JSON and XML.
  • Excellent problem-solving and stakeholder communication skills.

Desirable

  • Experience working with creative automation, design systems, DAM platforms, or video rendering technologies.
  • Knowledge of marketing technology, advertising production, or creative operations.
  • Experience building AI-powered tools in enterprise environments.
  • Exposure to AWS, Azure, or GCP.
