What I'd like to see on a job spec
Initially I scan for keywords that pique my interest:
- unit testing
Using the latest tech obviously stands out. For C++ the big shake up was C++11 -- so anything this modern is of interest -- but really we need to be talking at least '17.
However, very few companies seem to use '20 in production but a good example is Maven Securities. In fact, I do wonder if being so cutting edge might put people off!
But if a company is this up front about keeping up-to-date then it looks good to me.
In the details I like to see some hint of autonomy and trust. And you sometimes see something like "20% own project time", which is awesome. Unstructured training -- "play" -- is really important for development, and you'll often end up researching something that will benefit your day job anyway.
Some acknowledgement of environmental considerations also makes a company stand out. The objective of writing efficient code is usually to maximise throughput/core usage, but an interesting additional consideration is that we might write efficient code to minimise resource usage and power consumption.
Interviewing for senior dev roles can really be a drag; five interviews are common. I think an online coding test/exercise using HackerRank or Godbolt makes a great 1st interview and is insightful and time-saving for both parties.
A mixture of office and home working is convenient and effective for employer and employee. But I think some contact with your colleagues is beneficial (rather than fully remote).

If a company uses their own product to do the same job as the end user then it can only result in a better product.
