Your Role

As the Persona Manager at Musicow, you will be responsible for designing, maintaining, and scaling the unique personality, tone of voice, and behavioral guidelines of an artificial intelligence entity to ensure consistent and authentic brand representation across all digital channels.

Job Overview

The Persona Manager acts as the “creative director” for an AI’s identity. They bridge the gap between creative copywriting and technology, ensuring the AI maintains its designated character, backstory, and values. This role prevents the AI from breaking character, handles public relations risks, and ensures every piece of generated content aligns with the overarching brand strategy.

Key Responsibilities

• Identity Development: Create comprehensive style guides detailing the AI’s personality traits, catchphrases, limitations, and emotional intelligence levels.
• Content Oversight: Audit and refine social media copy, scripts, and automated responses to maintain strict brand consistency.
• Continuity Management: Track the AI’s ongoing narrative, fictional backstory, or public history so it never contradicts itself.
• Risk Mitigation: Define safety boundaries to prevent the AI from generating inappropriate, off-brand, or politically sensitive responses.
• Cross-Functional Collaboration: Partner with data scientists, prompt engineers, and marketing teams to train the AI models on the correct linguistic patterns.

Technical Skills

• Prompt Engineering: Writing and refining advanced text prompts (like system instructions and few-shot prompting) to steer the AI's tone and persona constraints.
• Natural Language Processing (NLP) Basics: Understanding how LLMs process language, handle tokens, and predict text to better influence their outputs.
• Model Fine-Tuning Knowledge: Knowing how to structure datasets and conversation logs to train a model on a specific brand voice.
• Data Curation & Guardrailing: Setting up safety filters, “system prompts,” and negative constraints to stop the AI from generating off-brand or inappropriate content.
• Content Analytics: Tracking engagement, sentiment, and interaction data to see how audiences respond to the AI persona.

Software & Tools

• AI Writing & Co-Pilots: Tools like Jasper, Copy.ai, or custom GPTs used to generate baseline content variations quickly.
• Social Media Management: Platforms like Sprout Social, Hootsuite, or Buffer to schedule, track, and analyze the AI's social posts.
• Collaboration & Knowledge Bases: Tools like Notion, Miro, or Confluence to host the AI’s extensive persona Bible, backstory, and brand style guides.
• Dataset Management: Tools like Airtable or Google Sheets to organize high-quality “golden datasets” (examples of perfect responses) used for AI training.

Custom Model Training Tools

• Kohya_ss: Training custom LoRAs (Low-Rank Adaptations) to teach AI models specific brand styles or characters.
• Civitai / Hugging Face: Sourcing, testing, and managing open-source base models and checkpoints.

Workflow Automation & Logic (Nice to Have)

These skills are a plus but not a need.

• Make.com / Zapier: Connecting AI APIs to design tools to automate repetitive asset generation.
• LLM Playgrounds & APIs: Direct experience managing outputs inside OpenAI Playground, Anthropic Console, or developer environments for models like Llama.

About You

• Proven experience in brand voice, copywriting, content strategy, or character/persona development.
• Hands-on experience with prompt engineering, including system instructions and few-shot prompting.
• Working understanding of how LLMs process language and generate text, and how that shapes tone and behavior.
• Comfortable structuring datasets and conversation logs to support model fine-tuning on a specific voice.
• Strong editorial eye, able to audit content quickly and flag anything off-brand, off-character, or risky.
• Excellent writing and storytelling skills, with an ability to document a persona's world in a way others can execute against.
• Experience partnering with data scientists, engineers, and marketing teams on a shared creative vision.
• Sound judgment around brand safety, PR risk, and sensitive or political topics.
• Highly organized, able to maintain continuity across a large and growing body of content.

We'd Love It If You Also Had

• Experience training or fine-tuning custom models, including LoRAs, on a specific brand or character voice.
• Familiarity with open-source model ecosystems such as Hugging Face or Civitai.
• Experience building or maintaining automated workflows connecting AI APIs to other tools.
• Direct experience working inside LLM developer environments such as OpenAI Playground or Anthropic Console.
• Background in entertainment, gaming, or virtual influencer/character work.
• Curiosity about the evolving landscape of AI personas, virtual artists, and interactive fan experiences.
