The above claim states that over 400 jobs were created by President Joe Biden according to the cited Instagram post. The Instagram post indicates that over 400,000 jobs were created monthly on average, and it cites the U.S. Bureau of Labor Statistics. The U.S. Department of Labor summarizes a part of the U.S. Bureau of Labor Statistics saying this: "With 12.1 million jobs added since President Biden took office... monthly average of 356,000 jobs over the past three months...." It has been around 28-29 months since Biden took office, so 12,000,000/28 is around 428,000, which would be over 400,000 total.
However, since the #s are so general (ie 12.1 million), and since we don't have information about when the jobs were created (2021 vs. 2023), it's misleading to say that Biden creates an average of 400,000 per month consistently.
Lastly, it depends on whether "creation" includes "recovery" - during the COVID-19 pandemic in 2020, unemployment skyrocketed, but in 2021, "The U.S. is currently experiencing a strong economic recovery, with 5.7% real growth in 2021 and 6.6 million Americans returning to work under President Biden." Many jobs were recovered in 2021 with the rollout of vaccinations.
