In this Principal‑level role, you’ll drive strategic direction and lasting impact for Gainsight’s largest and most complex global client partnerships. You’ll serve as a senior member on the Professional Services Team, delivering business‑critical programs, advising executive stakeholders, and shaping best‑in‑class delivery practices. This is an outstanding opportunity for a strategic thinker who thrives in highly complex, matrixed environments, influencing both internal and external teams at the highest levels.

• Architect, orchestrate, and ensure delivery of large‑scale, cross‑functional initiatives that drive measurable business outcomes and maximize client success and Gainsight value.
• Guide the design of scalable program governance, delivery, and measurement approaches, ensuring optimal resource deployment, margin optimization, and client satisfaction.
• Represent Gainsight as an executive sponsor in critical customer forums, executive business reviews, and SteerCo sessions, influencing decisions and building customer advocacy.
• Represent Gainsight as the executive point of escalation, negotiating complex issues and ensuring client relationships remain strong and mutually beneficial.
• Partner with executive sponsors (both client and Gainsight) to define both short and long‑term program roadmaps and drive alignment between client business outcomes and Gainsight’s offerings.
• Build and nurture trusted, executive‑level relationships within client organizations, advocating for strategic partnership and executive alignment.
• Support the definition of long‑term account strategy by anticipating evolving client business objectives and proactively identifying opportunities for value delivery, innovation, and expansion.
• Partner with internal stakeholders to identify and secure strategic cross‑functional resources, influence product direction, and drive company‑wide alignment for key accounts.
• Serve as a visible leader and mentor within the Professional Services organization—coaching, developing, and elevating program management excellence and thought leadership.

This is not a complete list of responsibilities, and the scope of the role may evolve with the needs of the team and business.

• 10+ years of relevant experience in enterprise program or project management, professional services, management consulting, or customer success, with a track record of managing global, strategic accounts. Bachelor’s degree required; advanced degree (e.g., MBA, MS in Engineering) or equivalent experience preferred.
• Demonstrated success leading large service contract programs with Fortune 500 clients, including experience with multi‑year, multi‑business‑unit engagements.
• Executive‑level stakeholder management and advisory experience (C‑suite engagement required).
• Proven ability to design and scale program and project management frameworks or methodologies across a professional services organization.
• Experience leading and mentoring others, fostering talent development at scale.
• Outstanding executive communication, strategic thinking, negotiation, and influencing skills.
• Expert proficiency in program/portfolio management tools, CRM software, and data analytics platforms.
