Image Generation Expert

About the Role

We are seeking highly skilled Image Generation Experts & Prompt Engineers to support a leading AI research lab's model training and data quality efforts. You'll craft precise prompts, generate high-fidelity images using state-of-the-art (SOTA) models, and apply expert post-processing techniques to refine assets. The work centers on stress-testing generative capabilities, fixing AI artifacts, and providing structured feedback to Research and Data Operations teams to guide the development of the next generation of frontier visual AI tools.

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. You will join a team of domain experts and together, you will shape the future of generative media.

Key Responsibilities

• Prompt Engineering & Generation: Craft, iterate, and refine complex text-to-image and image-to-image prompts using SOTA models (e.g., Midjourney, DALL-E 3, Stable Diffusion, Nano Banana 2 / Gemini 3 Flash Image) to achieve specific artistic and technical outcomes.
• Asset Refinement & Post-Processing: Utilize professional editing software (e.g., Adobe Photoshop, Illustrator) to seamlessly integrate AI assets, perform inpainting/outpainting, and fix common generation artifacts (e.g., hands, text, structural inconsistencies).
• Quality Evaluation & Benchmarking: Review generated outputs against defined aesthetic and technical rubrics, identifying edge cases, prompt adherence failures, and systematic model weaknesses.
• Spec & Golden Sample Creation: Contribute to the development of prompt instruction specs and create flawless "golden sample" image datasets to serve as internal quality benchmarks for model training.
• Cross-Functional Collaboration: Collaborate directly with Researchers and Ops teams to scope data projects, define visual quality criteria, and support evaluation efforts at scale.

Core Qualifications

• Professional Generative Experience: 2+ years of professional experience in visual arts, graphic design, or digital media, with a demonstrated, direct focus on AI-driven image generation.
• SOTA Tool Proficiency: Extensive hands-on experience generating images using leading AI models, combined with mastery of professional post-processing software (Adobe Creative Suite) for advanced editing and compositing.
• Advanced Prompting Skills: Proven ability to iterate on complex instructions to manage lighting, composition, style adherence, and photorealism.
• Analytical Detail: Strong attention to detail with the ability to apply evaluation rubrics consistently and objectively to visual media.
• Communication Skills: Excellent written and verbal communication skills—able to document prompt strategies clearly and provide actionable, structured feedback.
• Work Ethic: Ability to work independently, manage time effectively, and solve complex visual problems in a fast-paced environment.
