About the role
- This is your chance to shape legendary play that lasts a lifetime.
- This role sits at the center of a new and constantly evolving set of challenges.
- The problems are still being defined, and the approaches are actively being invented.
Responsibilities
- Design, implement, and continuously refine system prompts, character behavior definitions, and guardrails for our AI character platform.
- Build evaluation frameworks to measure character fidelity, response quality, and safety - establishing quantitative standards for what "in character" actually means across interaction types.
- Architect and implement RAG systems to ground character responses in canonical knowledge, including embedding strategies, vector retrieval, and relevance evaluation.
- Partner with creative and brand teams to translate character attributes - personality, voice, canon, tone, and boundaries - into precise, testable AI behavior and system requirements.
- Lead prompt versioning, regression testing, and model evaluation practices to ensure character behavior remains consistent across provider updates and model changes.
- Evaluate and adopt emerging techniques in prompt engineering, agentic design, and LLM evaluation that meaningfully advance the quality and reliability of character experiences.
- Deep expertise in prompt engineering - system prompt design, few-shot techniques, chain-of-thought, multi-turn conversation management, and structured output.
- Familiarity with how voice AI services work (TTS, STT) - enough to understand how spoken delivery shapes prompt and response design.
- At Hasbro and Wizards of the Coast, you'll collaborate with passionate teams to reimagine our iconic brands and create experiences that spark joy, connection, and community through the magic of play.
- Life & Family Support
Requirements
- 3+ years of experience building and shipping production LLM-powered systems.
- Hands-on experience with RAG architectures: embedding models, vector stores, chunking strategies, and retrieval evaluation.
- Proficiency with major LLM APIs (OpenAI, Google Gemini, Anthropic, or equivalent) and experience making principled decisions between them.
Skills
- This is where canon knowledge meets language model behavior, and where the quality of every character interaction gets defined and measured.
