• Drive proof-of-concept efforts, working with sales engineers and product experts to demonstrate tangible value

• Stay on top of product updates and industry trends to educate customers and shape the conversation around GenAI adoption

• Build long-term customer relationships and support post-sale success in partnership with our deployment and support teams

• Negotiate pricing and deal terms and work with legal to redline contracts

• Bring customer insights back to product and engineering teams to inform the future roadmap and improve the user experience

• Help define and iterate on our sales playbook - your input will help shape our go to market strategies

• Excellent communication and storytelling skills

• Technical acumen with the ability to establish credibility with technical decision makers.

• You thrive in fast-paced start-up environments and are energized by impact - you want to help evolve the playbook, not just follow one

• Driven and solutions-oriented; you know how to navigate roadblocks and keep deals moving forward

• Passionate about generative AI and excited to help customers navigate a rapidly evolving industry
