About the role

Millions of images on the web still have no description at all, which makes them invisible to blind and low-vision users. Vordex Tech builds accessibility tooling for publishers and e-commerce sites, and our alt-text generator is the feature customers ask about most. The current version describes what is in the image but not why it matters on the page. We want a freelancer to fine-tune a vision-language model that uses surrounding page context, and to evaluate it with our panel of screen reader users. Scope is about 20 hours per week for three months.

Fully remote.

Responsibilities

  • Fine-tune a vision-language model to produce context-aware alt text
  • Build an evaluation protocol together with our screen reader user panel
  • Package the model behind a FastAPI endpoint our product can call
  • Write a short report on failure cases and recommended next steps

Requirements

  • Experience fine-tuning vision-language or image captioning models
  • Comfortable with PyTorch and the Hugging Face ecosystem
  • Genuine interest in accessibility and WCAG guidelines
  • Can work independently and report progress weekly

Benefits

  • Approximately 20 hours per week for 3 months
  • Fully remote, flexible schedule
  • Rate negotiated based on experience
