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, using AI to evolve what a winning proposal looks like.

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 with AI, 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, AI-enabled deliverables, 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.

How you'll make a difference:

• Serve as a trusted partner and internal champion for all things RFP—becoming the go-to expert for proposal strategy and execution.
• Use AI to build new categories of customer-facing deliverables beyond the traditional written proposal, such as personalized microsites or interactive formats, in partnership with Sales, Marketing, and Presales.
• Bring an informed point of view on where AI can replace, accelerate, or improve existing RFP process steps, and pilot those changes.
• Own the end-to-end RFP, RFI, and security questionnaire response strategy and process from intake to submission.
• Maintain and improve a scalable, up-to-date knowledge base of commonly asked questions and approved answers using our RFP software, including:
• Ensuring all content is accurate, consistent and on-brand
• Reviewing new content and adding to the knowledge base as appropriate
• Partner with Sales and Go-to-Market operational leadership to ensure our process is measurable and built for maximum effectiveness and efficiency, including:
• Ensuring an effective qualification process and healthy RFP response rate
• Tracking and improving RFP win rates and turnaround times

Who you are:

• You have 5+ years of experience managing RFPs or proposals in a high-growth SaaS environment, preferably supporting enterprise or mid-market sales teams.
• You have strong project management instincts: you can hold multiple stakeholders accountable to a deadline without formal authority over them, and you know when to escalate versus push through.
• You have genuine, hands-on experience using AI tools to speed up or improve your work, and you can speak specifically to what worked, what didn't, and what you had to fix.
• You have a point of view on how AI will change proposal and deliverable work over the next few years, and you're energized by that change rather than protective of the process you know.
• You have an eye for what makes a customer-facing deliverable feel tailored and compelling to a senior buyer, whether or not that experience comes from traditional RFP work.
• You’re collaborative and low-ego—you know how to bring people together to get things done and aren’t afraid to chase down answers or ask for help.
• You’re excited by the idea of joining a company where your work will be visible, valued, and essential to how we win.
