I have about 10 yrs experience, and just conducted my first job hunt in 5 years (I was with one company for a long time, then took a sabbatical for half a year after our dev team was off-shored). I was pretty concerned that it could take 6 months or more to find a gig. But I found myself interviewing with 6 or 7 companies within two weeks, and had 2 offers by the end of week 3 (I'm starting the new gig tomorrow). I consider myself a pretty average full-stack rails/react dev. I don't even bother applying to FANG (or whatever the acronym is now) jobs. So... I don't know if I just got lucky, but the job market felt pretty good when looking for senior roles. My interviews were a mix of referrals from previous coworkers, a couple recruiters reaching out, and (the job I accepted) from reaching out on LinkedIn to hiring managers posting jobs.
It feels like the AI wave is killing junior jobs, but driving demand for experienced developers to harness it, even if just harnessing it as a tool to speed up coding.
I fumbled a bit early in my career and burned some bridges, but luckily, I smartened up after the first 2ish years.
I figured if I have 10+ years of experience and do not have at least 5-10 people I can call up to ask for a job who've worked with me in the past, I've screwed up. Investing in relationships has been the key job security hack for me (also a completely average React dev who happens to know an above-average amount about video and webrtc).
For those just getting started, my piece of advice is to be OK taking a lower rate initially, and just keep pushing it higher until you find resistance. If you're good at what you do, you will quickly find that you will get referrals (make sure to ask!) and can charge a ton more. It's a lot easier as a freelancer/contractor than a salaried employee since the market is much more liquid (you spend less time at one gig) and therefore you can test the waters with a higher rate much more often.
Regardless, what these companies list as what they will pay hourly isn't necessarily what you have to ask for. If you think about it from a negotiation perspective (and you have the ability to sell yourself), these are simply just the lower bound of what you can ask for.
Referrals are the key.
