📋 Description

• You’ll be the primary point of contact and strategic partner for a portfolio of key accounts. Your mission: drive adoption, ensure success, reduce churn, and uncover expansion opportunities. • Own the end-to-end customer journey: From post-sales handoff through onboarding, implementation, QBRs, renewals, and expansion. • Monitor and act on account health: Proactively assess usage, satisfaction, and risk signals. • Orchestrate cross-functional support: Loop in Engineering, Product, Support, and Sales when customers need technical help, product guidance, or commercial discussions. • Drive product adoption: Ensure customers understand and leverage new features, best practices, and Promptfoo’s full capabilities. • Manage critical workflows: Track POC milestones, implementation timelines, renewal dates, and stakeholder engagement plans. • Lead QBRs and strategic reviews: Prepare agendas, slides, insights, and action plans—and facilitate high-impact business conversations. • Triage and escalate support issues: Monitor critical tickets, ensure SLAs are met, and close the loop with customers once resolved. • Identify expansion opportunities: Spot use cases for scale, additional teams, or advanced features—and partner with Sales to act on them. • Amplify the voice of the customer: Share qualitative and quantitative feedback with Product and Engineering to shape Promptfoo’s roadmap. • Contribute to scalable resources: Update light-touch documentation, FAQs, or onboarding materials based on recurring customer needs.

🎯 Requirements

• 3+ years in Customer Success, preferably at a developer-focused, PLG, or technical B2B SaaS company (AI/ML, DevTools, or infrastructure a plus). • Deep empathy for developers and technical users—you speak their language and understand their workflows. • Comfortable navigating CLI tools, APIs, GitHub, or similar technical environments (you don’t need to code daily, but you’re not afraid of technical context). • Exceptional organizational skills—you juggle multiple accounts, deadlines, and stakeholders without dropping the ball. • Proactive communicator who builds trust quickly, both externally and internally. • Data-informed: you use product usage, support trends, and customer feedback to guide decisions. • Startup-ready: scrappy, resourceful, and energized by ambiguity and high impact.
