Think about what you want to do, what the company allows you to do, and what the next job will give you. Generally speaking one 6 month stint every 5-10 years won't be questioned extensively in tech. The next job you get you'll need to hold for 18-24 months to avoid the appearance of a pattern. Be sure that you have a good reason for leaving that isn't "the tech stack was a mess" or "I didn't fit in with the culture" and find your next opportunity. If you make it to a full year no one will ask detailed questions about why you left.
