Answer these questions:
- Who are you?
I need to research a company before I send you my work DNA (a.k.a. resume`). Are you a spammer? Are you some recruiting company building a resume`s database?
Be honest and avoid snake-oil salesmen terms like "Company in the bay area with a huge upside". If I work for you, I have to believe in your vision as much (if not more) as you do and I can't do that without doing due diligence and researching your company.
If you are not well established yet, then a brief description of what you do and what your vision is always helps (in your case, a link to your site should suffice).
- What do you need from me? / What does your technology stack look like?
Be very specific about must haves and "would be nice"es. You can discourage a lot of potential candidates by putting a laundry list of technologies that you're thinking about (or worse, toying with the idea of) implementing in the future but are in no way what you need from a candidate right now.
- What is your compensation package?
Not always feasible to write in detail, but putting a salary range is a huge plus. A phone interview + a couple of on-site interviews (taking time off of my current job) to be told that your maximum offer is worth $20k less than what I make right now is a waste of everyone's time.
Aside from that, everything else is just fluff in my opinion. Good luck!
