Role Overview

Join Brightvision's development team to build Coseller, a cutting-edge B2B sales technology platform that combines AI-driven outreach automation with deep company and contact intelligence. This proprietary platform serves the European B2B tech market, positioning itself at the intersection of AI SDR tools and data enrichment platforms.

We're hiring for two specialized roles: Profile A focuses on building AI-powered Sales Development Representative modules with automated email and LinkedIn outreach capabilities, while Profile B centers on developing data intelligence engines for contact enrichment and search functionality. You'll be working on greenfield development, shaping products from the ground up rather than maintaining legacy systems.
