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.

Supervisory Responsibilities:

N/A

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.
• Own the end-to-end RFP, RFI, and security questionnaire response strategy and process from intake to submission, including:
• Defining what it means to qualify an RFP/RFI, balancing factors like effort, quality and ROI
• Importing qualified questionnaires into our RFP software
• Drafting and refining initial answers to technical, functional, and business questions in RFPs and RFIs
• Sourcing and validating inputs from subject-matter experts across the company (e.g. Sales, Product, Legal, Security, Product Marketing)
• Packaging and delivering proposals in a compelling, differentiated way that helps us win
• 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're an exceptional project manager—organized, detail-oriented, and comfortable juggling multiple complex deliverables under tight timelines.
• You have excellent writing, editing, and communication skills, with a strong instinct for tailoring content to different audiences.
• 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 systems-minded and always looking for ways to improve the process—whether that's introducing a new tool, optimizing workflows, or creating better documentation.
• You understand the nuances of enterprise buying processes and what it takes to compete in a crowded market
• You're excited by the idea of joining a company where your work will be visible, valued, and essential to how we win.
