Mixedbread recently lauched its first product and we're building momentum across product, go-to-market, and customer success. We are looking for someone exceptional to help accelerate our growth.

What you'll do
- Lead Mixedbread's GTM motion: Architect and manage our marketing CRM, segment leads, develop campaigns, and design systems that drive acquisition and engagement
