About the Role

Manifest is hiring a Strategic Account Manager to own its largest, most strategic accounts — including Fortune 500 companies — the company's top priority for 2026 and beyond. You'll be the end-accountable owner for these clients: their executive-level partner and the internal driver of their success. You'll convert pilots into multi-year, expanding partnerships while working across Product, Operations, Sales, and Marketing to deliver on complex engagements.

What You’ll Do

• Own executive relationships and lead business reviews with C-suite stakeholders
• Convert pilots into full launches and drive multi-year renewals and expansions

• Oversee onboarding including data migration, security reviews, and tech implementation
• Bring enterprise client needs to Product and Engineering to influence the roadmap
• Partner with Sales on account planning, renewals, and expansion proposals
• Define the enterprise account management playbook and set team-wide standards

What We're Looking For

• 8+ years in enterprise account management or client success at a B2B SaaS company
• Proven track record owning and growing Fortune 500 or equivalently complex accounts
• Executive presence with experience managing senior, multi-stakeholder relationships
• Ability to hold cross-functional teams accountable to client outcomes
• Strong analytical skills and comfort using AI tools to increase output
• Experience building or formalizing enterprise account management processes
• Familiarity with legal tech, professional services, or regulated industries
• Bachelor’s degree or equivalent practical work experience.

This is for you if....

You want end-to-end ownership of accounts that actually matter to the business. You thrive at the intersection of relationship management and operational complexity. You want to shape how a category-defining company serves its most important clients.

This is not for you if....

You prefer a defined playbook over building one from scratch. You're uncomfortable with direct accountability for client retention and growth. You want remote flexibility — this role is fully in-office, five days a week.
