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
Ensure client KPIs and contractual commitments are met; get ahead of risks early
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.
