Senior Account Manager, Enterprise (New York)

Fifth Dimension is ushering in a golden age of work, where boring tasks are automated away, the right data are always at your fingertips, and maximal creativity is encouraged.

We’re an early stage start-up with ample runway, backed by leading European and American investors.

The founders, Johnny Morris and Dr. Kate Jarvis, are both data nerds. But that's not all. Johnny’s got 16 years’ experience in Real Estate, our GTM niche. Kate’s got a PhD in Linguistics from Stanford plus 12 years’ CPTOing across Silicon Valley and London startups. We're demanding, excitable, encouraging of experimentation, adoring of bad puns, and have built our business on a foundation of compassion and kind challenge.

Real estate finance moves billions, but still works in spreadsheets. You'll own the accounts proving AI can automate 60% of institutional workflows - and expand them from single teams to firm-wide platforms.

• Monday : Build strategic account plans for three new enterprise customers - map organizations, identify champions, design onboarding for expansion.
