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 usingcutting-edgeLLM 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’semergingneeds, making this ideal for someone who thrives in ambiguity, moves fast, and gets energy from building things thatdidn’texist yesterday.

KEY RESPONSIBILITIES

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.

• Generate and evaluate new POC ideas on a rolling basis, aligned to client prioritiesidentifiedin weekly sessions with the Fractal lead and client stakeholders.

• Progress high-value POCs frominitialconcept through to business-prototype stage, suitable for demonstration to senior stakeholders including global leadership.

• Apply strong product intuition toidentifywhich concepts have the highest potential for business impact andscalability andfocus effort accordingly.

Collaboration & Stakeholder Engagement

• Attend in-person working sessions at the client’s London office on Tuesdays, Wednesdays, and Thursdays each week.

• Participate in brief daily or weekly sync sessions with the Fractal Engagement Manager to align on priorities, share progress, and incorporate feedback.

• Present prototypes and technical approaches to client stakeholders, articulating both the business value and technical underpinnings of each solution.

• Operate as a self-directed contributor within a small, high-trust team-comfortable navigating ambiguity and taking ownership without detailed specifications.

Documentation & Handoff

• Document prototypes, technical approaches, architectural decisions, and outcomes to a standard suitable for handoff into the client’s global product pipeline.

• Contribute to a showcase deliverable targeting mid-June 2026, presenting select POCs to client stakeholders including global leadership.

• Create lightweight but clear technical documentation that enables other engineers to understand, extend, orproductionizeprototype solutions.

REQUIRED QUALIFICATIONS

• 5 + years of professional experience in software engineering, ML engineering, or applied AI development.

• Strongproficiencyin 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.

• Ability to move from idea to working prototype extremely quickly-comfort with imperfect code, fast iteration, and progressive refinement over waterfall planning.

• Strong communicationskills-able to demo prototypes, explain technical concepts to non-technical stakeholders, and articulate the “so what” of each solution.

• Self-directed and adaptable-comfortable working without detailed specifications in a fast-changing, priority-shifting environment.

PREFERRED QUALIFICATIONS

• 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

• Engagement Type:Fractal FTE, embedded withinClient’s EMEIA team at the client’s London office.

• Primary Location: Client office, Central London

• In-Person Days: Tuesday, Wednesday, Thursday each week.

• Remote Days: Monday and Friday (flexible).
