We are looking for a GenAI Prototyping Specialist to be embedded within Fractal’s EMEIA team, focused 100% on new capability development. This is not a reporting or maintenance role - it is a fast-paced, innovation-first position where you will rapidly conceptualize, build, and iterate on proof-of-concept AI solutions using cutting-edge LLM tooling.
You will work in close collaboration with the Fractal Engagement Manager and client stakeholders to identify high-value GenAI use cases aligned to client priorities, progress the strongest concepts from initial POC through to business-prototype stage suitable for senior stakeholder demonstration, and contribute to showcase deliverables targeting global leadership audiences.
The work is adaptive in nature - there is no fixed project plan or pre-defined requirements document. Priorities are set collaboratively on a rolling basis in response to the client’s emerging needs, making this ideal for someone who thrives in ambiguity, moves fast, and gets energy from building things that didn’t exist yesterday.
Rapid Prototyping & POC Development
Rapidly conceptualize, build, and iterate on proof-of-concept GenAI solutions using LLM tooling including Claude Code, and client-specific LLM platforms and tools.
Collaboration & Stakeholder Engagement
Document prototypes, technical approaches, architectural decisions, and outcomes to a standard suitable for handoff into the client’s global product pipeline.
Strong proficiency in Python for rapid prototyping, data manipulation, API integration, and ML model experimentation.
Hands-on experience with GenAI/LLM application development - including prompt engineering, RAG architectures, tool use, and agentic workflows.
Demonstrated experience using AI-assisted coding tools (e.g., Claude Code, GitHub Copilot, Cursor) as a core part of the development workflow to accelerate prototyping velocity.
Working knowledge of ML fundamentals: classification, regression, clustering, NLP, embeddings, and model evaluation.
-
Experience with multiple LLM providers and platforms (Anthropic Claude, OpenAI, open-source models via Hugging Face) and the ability to select the right model for the task.
-
Familiarity with front-end development (React, HTML/CSS, Streamlit, Gradio) for building interactive demo interfaces around AI prototypes.
-
Experience with cloud AI services (Azure OpenAI, AWS Bedrock, GCP Vertex AI) for model hosting and API integration.
-
Background in marketing technology, digital marketing, or consumer-facing product development.
-
Experience working in embedded consulting or contractor roles within large enterprise environments.
-
Familiarity with vector databases (Pinecone, ChromaDB, Weaviate) and semantic search architectures.
-
Prior experience building and presenting POCs or demo prototypes to senior/executive stakeholders.
-
Experience with multi-agent frameworks (LangGraph, AutoGen, CrewAI) or workflow orchestration tools.
ENGAGEMENT MODEL & WORKING ARRANGEMENT
Bachelor’s degree in computer science, Data Science, Machine Learning, Software Engineering, or a related technical field. Master’s degree is a plus but not required. Self-taught engineers with strong portfolios and demonstrated prototyping ability are welcome.
