How do you keep an eye on the job market realistically as a mid-level engineer in big tech without losing focus on your current role?

I just landed my first role in big tech after a very unconventional and challenging journey. I really want to focus on learning, growing, and making the most out of this opportunity. That’s my top priority.

That said, I also don’t know how stable things are (market-wise, org-wise, etc.), and I don’t want to be caught off guard if things change suddenly. So I want to ask: what does it actually look like to keep an eye on the market while you're ramping up in a new job?

• Should I regularly check LinkedIn job postings?

• Is it a good idea to casually apply every now and then, even if I’m not planning to leave soon?

• Are there specific signals or habits engineers use to stay informed without spreading themselves too thin?

I’m not trying to jump ship, I just want to be smart and prepared without compromising my focus or coming across as disengaged. Especially since I'm not a senior engineer yet, I don't know even know what type of jobs I could potentially look at if things go south.
