I'm a software engineer and I work in an air-conditioned office. I've been sneezing at least 23 times a day lately, and it's always in bursts of 12 sneezes. This is all pretty new to me, and I'm guessing it might have started since I joined the IT industry. What could be causing this sudden change, and how can I find some relief?

It sounds like your sneezing could be related to allergies triggered by indoor air quality, such as dust, air conditioning, or dry air commonly found in office environments. Using a humidifier, ensuring regular cleaning of the office, and considering antihistamines might help reduce the sneezing. If it persists, a consultation with an allergist could be beneficial.
