If I were a pre-seed or seed-funded startup with limited hiring resources to find talent, as a Talent Acquisition Partner here is what I'd do.
1. Utilize LinkedIn, targeted boolean searches, and filtered searches to narrow in on my desired candidate profile. Create templates that easily and simply outline your mission and role when doing candidate outreach. Be transparent about the compensation for the role.
2. Dedicate time to comb through resumes and profiles on LinkedIn. (Applicants if you are using job boards.) Ideally, use a combination of both.
3. Differentiate whether a 1099 independent contractor or dedicated W2 is necessary for what immediate goals I would want to accomplish to move the needle forward in my business. (Are we trying to attract investors, bring our technology in-house, etc.) Assess how much "dedicated help" is needed over time.
4. Establish a clear scope of work that the candidate would need to be doing along with milestones. Considering there is probably a clear budgeting runway depending on rounds of funding, flesh out what can reasonably be done within that funding runway.
eg. Whether you have 1.5 years of budget for the role, or it is a short project, really flesh out what needs to be done within that time until the next rounds of funding and move the needle.
