Data Scientist

What You’ll Do

• Prospect every day. Run high-volume outbound across phone, email, and Facebook/LinkedIn to decision-makers at dental practices.

• Qualify and book. Have real conversations, qualify against our ICP, and book demos on AE calendars.

• Own your book. Work a defined segment / platform book and avoid double-touching prospects.

• Keep HubSpot clean. Log every call and touch the same day; keep records complete — if it isn’t in HubSpot, it didn’t happen.

• Follow the rhythm. Join the daily standup and protect your power-calling blocks.

• Hand off well. Pass qualified demos to AEs with the context they need to win.
