    • Writing personalized outreach messages with strong copywriting skills
    • Navigating ATS/CMS tools with confidence
    • Communicating clearly and professionally at every stage
    • Managing time well, even across parallel hiring flows

     

     Our Hiring Flow:

    1. Initial screening (by recruiter)
    2. Technical interview (by our internal team)
    3. Final interview with leadership (by our internal team)
    4. Send feedback or offer to candidate (by recruiter)
    5. 3-month probation period

     

    What We’re Looking For:

    • 2+ years of experience in IT recruitment
    • Solid sourcing skills (LinkedIn, Boolean, etc.)
    • Ukrainian — fluent; English — Upper-Intermediate+
    • Proactive, structured, and results-oriented
    • Available to jump in when we have active roles
    • Comfortable working independently and owning outcomes

     

    Compensation:

    • $300–600 per successful hire, depending on role level
    • Optional base rate — negotiable during active hiring periods
    • Payment in 2 stages: after offer acceptance & after candidate starts probation
    • We’re open to ongoing collaboration if we’re a good match
