  • 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 effort, quality and ROI
    • Importing qualified questionnaires into our RFP software
    • Drafting and refining initial answers to technical, functional and business questions
    • Sourcing and validating inputs from subject‑matter experts across the company (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 it 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

  • 5+ years of experience managing RFPs or proposals in a high‑growth SaaS environment, preferably supporting enterprise or mid‑market sales teams.
  • Exceptional project manager—organized, detail‑oriented and comfortable juggling multiple complex deliverables under tight timelines.
  • Excellent writing, editing and communication skills, with a strong instinct for tailoring content to different audiences.
  • Collaborative and low‑ego, able to bring people together to get things done and chase down answers or ask for help.
  • Systems‑minded and always looking to improve the process—whether that’s introducing a new tool, optimizing workflows or creating better documentation.
  • Understands the nuances of enterprise buying processes and what it takes to compete in a crowded market.
