You can't ... the best case for you it the developer needs to be either losing their gig or not happy with their current situation. If they are currently "happy" with their gig you will really need to wow them with an offer or something significant. Frankly most developers need to be intrigued. They are NOT going to just quit their gig just to write your code you've already done all the designs and picked the tools. Its going to take a lot of time and effort on the hiring companies part to make the developer feel great about the opportunity. Do they get to hire their supporting cast? Do they get a say in whats happening with the project?
This is me in a nutshell. I was very happy as a senior Solaris developer [curmudgeon: "full stack, eh? Does that start at the firmware and go up to the browser, or did you forget something?"], until suddenly I wasn't and have been actively looking for work for 4 months now.
While I had some talks with other companies prior to getting retrenched, I didn't make any moves because I was committed to what I was doing, was the "go to" person for several teams in disparate areas, and had significant responsibilities and influence.
Now, though, while I'm upskilling on a heap of technologies that I never needed to know beforehand, I'm paying careful attention to how ads are written and noticing what @DerekD mentioned about frameworks vs languages.
Another thing about resumes / linkedin - my experience is that while it's easy to add a new position, writing a blurb which advertises you sufficiently (let alone well!) is difficult - or is that just because I'm hesitant to blow my own trumpet?
In today's world, I think it makes sense for software folk to switch companies every 5 or 6 years. I think the exception would be when one is shifting technologies and keeping up with new stuff within the same company (which is rare outside of consulting).
If Australian companies are anything like the U.S., I would think that some knowledge about micro-services, Kubernetes and related products, and cloud platforms like Azure/AWS are hot now.
Indeed, those parts of tech are really hot right now. I'm behind the curve on my adoption because I was really happy in my ivory tower.
Having started my career in universities (where tenure is still a thing), moving to Sun (for my dream job with my dream company) I fully expected to be with that company until I retired. Now that that ride has ended, I reckon I've got 20 years worth of fulltime work left in me and I have to rejig my mindset to expect that I might work for 5-10 companies in that time.
