About the job

Requirements

Responsibilities
  • Serve as the primary point of contact for client onboarding, building and maintaining strong working relationships across both organizations.
  • Own the end-to-end onboarding checklist for each new account, prioritizing what is needed up front versus what can follow later.
  • Communicate with clients throughout the process to gather input, understand all parties' expectations, and shape effective communication plans, handoffs, and stage gates.
  • Attend relevant client and internal meetings regularly to stay current on account status, timelines, and priorities, and to catch issues in real time.
  • Proactively reach out to internal and client-side teams to gather needed information.
  • Resolve routine onboarding tasks directly wherever possible, escalating genuinely stuck items with a clear, specific ask.
  • Track key deadlines and milestones across active accounts, escalate issues, and update plans and timelines as circumstances change.
  • Maintain a clear, up-to-date view of commitments made to and by each account.
  • Keep a shared calendar or reference of standing meetings and touch points between the two teams, and recommend changes when meetings are not adding value or a gap needs to be filled.
  • Partner with Program Managers to ensure they receive the information needed for a successful close.
  • Educate points of contact and stakeholders on strategy, and uphold and adopt established guidance.
  • Develop a thorough understanding of the business to uncover opportunities for improvement, identify new opportunities, and respond to ad hoc requests.
  • Contribute to reusable tools such as standard onboarding checklists, templates, and process documentation.
  • Provide regular status reporting and guidance to leadership on account health, risks, and progress.
Desired Qualifications
  • Experience in financial services, energy, infrastructure, or another asset- or transaction-heavy industry.
  • Prior experience with client onboarding, account transitions, or post-acquisition or merger-and-acquisition integration.
  • Familiarity with service transition or asset management agreements, including TSAs and AMAs, and related documentation.
  • Background in accounting, finance, or transaction support sufficient to recognize issues that need specialist input.
  • Experience operating across two organizations or cultures, such as client/vendor or acquirer/portfolio company environments, and building trust on both sides.
  • Project management certification, such as PMP or CAPM, or equivalent training.
  • A track record of taking on responsibility beyond one's title or tenure and delivering results.
