Yes. Health AI training and evaluation work is carried out remotely, in your own time, at times of your choosing.

Do I need technical or coding skills?

No. Clinical judgement and real-world experience are what is required. Most tasks involve reading, reasoning, and writing assessing AI outputs, defining reference answers, and quality checking responses.

Is patient data involved?

No identifiable patient data is used.

Is this a job or freelance contract work?

This is contract project work, not employment. Most arrangements are flexible and task-based rather than salaried. You will be contracting directly with Mercor or Micro1, not with this site.

Can I do this alongside NHS or locum work?

In many cases yes subject to your employer's policy on secondary work and any conflicts of interest.
