blockchain developer needed for long term job on my team.

hello
I want to build a privacy token based on the bitcoin code base
And now I want to connect to the ETH ecosystem
So they have to wrap their token
And launch it on the polygon chain (for low fees)
They are very skeptical
So I just need to make sure that the devs what i hire will know what they are doing,
I will share whitepaper via interviews.
Thank you
