Should I accept job offer or do my master's? [D]

I graduated with my bachelor's in a top 3 CS program and have had a rough recruiting season. I received a full time offer as AI Product Engineer at a tax software company, where they are trying to become more AI native. It's essentially a PM + AI engineering role. Long term I'd love to work at a frontier lab or in a research/more technical role at an AI startup. So, should I take up the offer or pursue my master's at the same school? I am able to defer my master's but don't feel fully comfortable accepting
