There are many things, but start with the basics: 1st) Tell the salary upfront; 2nd) tell the interview process (luckily it's non-bullshit and not too long). AFAICT there are many permanent senior engineers that are happy in their jobs and couldn't care less about yet another job offer without salary info because it may seem like yet another clueless recruiter wants to lowball them and waste their time. And going through excruciating process to get 5% more is also not something that many people will do. But your offer might actually be better than what they expect, and it's a good starting point. Also, senior engineers might actually care more about work life balance and stability than crazy high contracting rates. (Of course depends on the person).
