Questions

Can a foreigner apply for these roles?

91 of the 92 roles here state no citizenship or security-check demand. A role that does says so in its advert, and the card marks it.

Which companies hire most AI engineers?

Mistral AI (15), Meta (11), Datadog (5), Sigma Nova (5), InterDigital (4).

Which roles count as AI jobs?

Every engineering, research, product and infrastructure role whose title and advert make AI its work - machine learning and AI engineers, research scientists, LLM, agent and MLOps engineers, computer vision and speech, AI chips and data centers, embodied AI - at any employer, read by Alion's AI role classifier. Data analysts and data engineers are left out, and so is a role that only mentions AI tools.

How fresh is this?

Every role is re-checked on the employer's own careers board at least every 48 hours, and the page is rebuilt every night.
