About The Position

The Senior Executive Strategy & Planning Manager is a key member of a senior executive’s Chief of Staff organization, playing a pivotal role in shaping and supporting the organization’s strategic initiatives and leading the development of AI agent-driven automation across the Chief of Staff function. This role sits at the center of the Product & Engineering (P&E) organization’s leadership operating model, working directly with the CIO and their senior leadership team in a fast-paced environment to ensure the organization is moving with clarity, alignment, and velocity against its most important priorities. The role provides a unique opportunity to work with and learn from some of the senior-most technology leaders in the company. The work of this role spans five interconnected areas: Strategic materials development, Rhythm of Business, Quarterly Delivery Plan ownership, AI agent development, and Executive briefing and communications. At various times this role will also serve as a proxy for the Chief of Staff, extending the Chief of Staff’s reach across functional partners and driving priorities forward. Success in the role requires exceptional business acumen, discretion, a sense of urgency, strong project management skills, collaborative relationship-building, and executive presence. Equally important is hands-on experience with AI tools and an eagerness to keep experimenting, building, and growing as an agent developer. Experience in strategy or management consulting is highly valued, given how much of this role centers on structuring complex problems, building and maintaining relationships, and constructing credible narratives at speed.
