micro1 is engaging Excel Specialists to support a customer’s initiative focused on enhancing an LLM’s proficiency in creating, understanding, and modifying Office Open XML files—including complex .xlsx, .docx, and .pptx documents. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.


Scope of Work

  1. Design and simulate challenging, realistic business scenarios that require expert-level use of Excel, PowerPoint, and Word, mirroring tasks from your professional experience.
  2. Engage in structured, multi-turn conversations with an LLM, presenting complex document-related prompts and evaluating AI-generated deliverables.
  3. Create and review Office documents (.xlsx, .docx, .pptx), assessing two AI-generated solutions against professional standards and selecting the preferred output.
  4. Document feedback and provide detailed, side-by-side preference data to inform AI model improvements, focusing on quality, accuracy, and business relevance.
  5. Contribute domain-specific insight across multiple industries and business functions, ensuring the data collected covers diverse, real-world use cases.
  6. Communicate clearly and thoughtfully in both written and verbal formats to ensure precise understanding and actionable feedback for the AI training team.


Preferred Qualifications

  1. Minimum 3+ years of professional experience working in Fortune 500 environments using Excel, PowerPoint, and Word on high-impact business projects.
  2. Demonstrated expertise in creating complex models, reports, analyses, and presentations across various industries such as finance, healthcare, tech, consulting, or retail.
  3. Background in business roles such as private equity associate, investment banking analyst, junior consultant, FP&A analyst, HR, or marketing strategist, with hands-on involvement in deal or project work.
  4. Proficiency in designing use cases reflecting functions like strategy, operations, sales, marketing, finance, or HR.
  5. Exceptional written and verbal communication skills, with a keen eye for detail and clarity in articulating feedback.
  6. Experience interacting with LLMs or writing long-form prompts for AI tools is a strong plus.
  7. Strong analytical mindset and ability to evaluate nuanced differences in document quality and business applicability.
