Sr. Proposal Manager

At Klaviyo, we value the unique backgrounds, experiences and perspectives each Klaviyo (we call ourselves Klaviyos) brings to our workplace each and every day. We believe everyone deserves a fair shot at success and appreciate the experiences each person brings beyond the traditional job requirements. If you’re a close but not exact match with the description, we hope you’ll still consider applying.

About The Team And Role

At Klaviyo, our mission is to empower creators to own their growth. As we scale, the RFP process is becoming an increasingly strategic part of how we compete and win with some of our most sophisticated customers. We're looking for a high-performing Proposal Manager to lead the charge in building and scaling our RFP response function. This is a high-leverage, high-impact individual contributor role with significant visibility and influence across the go-to-market organization. You’ll be the first dedicated hire focused on RFP excellence—meaning you’ll play a critical role in shaping the systems, processes, and strategy behind how we respond to customer questionnaires.

You won’t be building from scratch - we already have RFP software and practices in place - but you will have the opportunity to define best practices, elevate our approach, evolve our systems, and generally raise the bar for how Klaviyo shows up in competitive sales cycles. You’ll find strong support and eager partners across Sales, Presales, Marketing and other parts of the business. This is a chance for someone with the right experience to shape the future of the proposal management function at a world-class SaaS company - while also directly impacting revenue, win rate, and brand perception. This role is in the Presales organization, which also includes Presales Solution Architects and our Demo Experience team.

If you're someone who thrives on crafting compelling narratives, managing complex cross-functional projects and influencing strategic sales outcomes through precision and clarity—this role could be for you. What you’ll get in return is the opportunity to be part of an extremely high-performing, strategically-important team that works at the exciting intersection of engineering, sales and customer engagement.
