Enterprise Marketing Domain Expert

Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models.

1. Overview

Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking senior Enterprise Marketing subject-matter experts (SMEs) to act as the quality authority on how real marketing work gets done, and to elevate the quality of our AI training data. This is a full-time commitment of 40 hours per week.

This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

2. Key Responsibilities

• Guide research and engineering teams to close knowledge gaps and improve AI model performance in enterprise marketing, demand generation, content, paid media and communications.
• Review AI-generated prompts and multi-step marketing workflows for realism, flagging unnatural phrasing, academic-sounding tasks and constraints no real marketing team would face.
• Design realistic marketing tasks, the way a marketing manager would actually brief them, and write polished, executive-quality solutions such as campaign plans, web, email and ad copy, research briefs and PR material.
• Evaluate marketing tasks and solutions against rubrics and provide clear, written feedback.
• Validate and refine evaluation rubrics so they reward what a senior marketing leader would consider good work.
• Collaborate with other subject matter experts to ensure consistency and accuracy in training data.

3. Core Qualifications

• 10+ years of professional marketing experience inside an enterprise marketing organization, in-house at a large company or at a recognized agency serving enterprise clients.
• A track record of meeting or exceeding campaign ROI, ROAS or lead-generation targets, with specific results you can point to.
• Hands-on depth in market and audience research, copywriting (web, email, ads), paid media planning, SEO and PR.
• Daily working and administration experience with enterprise marketing tools such as Marketo, HubSpot, Salesforce and GA4, plus Jira, Confluence, Workspace productivity tools (Docs, Sheets, Slides) and Microsoft Office.
• A sharp editorial eye and strong taste for polished, customer-facing work.
• Demonstrable career progression (e.g., Marketing Manager → Senior Manager → Director or Head of Marketing).
• Ability to engage reliably for at least 40 hours/week during weekdays.
• Strong written communication skills and the ability to explain judgment calls clearly.
