About the role

This role is the tip of the spear for Flex's largest, most complex, and most strategically important deals. As we expand into new verticals and new enterprise relationships, we need a technical sales leader who can do more than present a demo.

What they're looking for

  • 10+ years of experience in pre-sales, solutions engineering, or technical sales, with at least 4 years operating in a senior or lead capacity on complex enterprise deals
  • Demonstrated track record closing large, multi-stakeholder, technically complex sales cycles, ideally in FinTech, PropTech, payments, or adjacent SaaS/infrastructure categories
  • Exceptional ability to engage and build credibility with C-suite and VP-level technical buyers, equally comfortable in a boardroom and in a technical architecture review
  • Deep fluency in enterprise integration patterns (APIs, webhooks, data pipelines, ERP/property management system ecosystems) with the ability to get hands-on when needed
  • Strong commercial instincts: ability to shape deal structure, anticipate objections, and understand how technical decisions affect economics on both sides of the table
  • Experience operating in a greenfield or early-stage vertical context. Comfortable building process, playbooks, and teams from scratch rather than inheriting them

Will you be a part of the team?

This role is the tip of the spear for Flex's largest, most complex, and most strategically important deals. As we expand into new verticals and new enterprise relationships, we need a technical sales leader who can do more than present a demo. You'll own the solution layer of the sales process end-to-end: translating complex customer environments into winning proposals, building conviction with technical and executive stakeholders alike, ensuring that what we promise is something we can...
