I'm currently working on an AI strategy project for the Foundational Research Institute; they are hiring and do not require plenty of experience:

Requirements

• Language requirement is research proficiency in English.
• We anticipate that an applicant is dedicated to alleviating and preventing suffering, and considers it the top global priority.
• A successful applicant will probably have a background in quantitative topics such as game theory, decision theory, computer science, physics, or math. But we welcome applicants regardless of background.
• Peer-reviewed publications or a track record of completed comparable research output is not required, but a plus.
• There is no degree requirement, although a PhD is an advantage, all else equal.

Their open research questions include a number of AI-related ones, and I expect many of them to still have plenty of low-hanging fruit. I'm working on getting a better handle on hard takeoff scnearios in general; most of the my results so far can be found on my website under the "fri-funded" tag. (Haven't posted anything new in a while, because I'm working on a larger article that's been taking some time.)
