I work as head of the one on one team for 80,000 Hours. Previously I worked at the Global Priorities Institute, ran Giving What We Can and was a Fund Manager at the Effective Altruism Infrastructure Fund.

Brenton Mayer runs internal systems at 80k. That basically means operations and impact evaluation, ie the parts that don’t really get visibility or interact with the outside world. He’s been doing that extremely competently for years. Him and his team make it feel easier to work to a high standard (eg through making sure we get more of a sense of how we’re impacting users and setting an ambitious but sustainable culture), keep the lights on (figuratively by fundraising and literally) and make 80k a lovely place to work.
