About the role

Key responsibilities & impact

Own your customer portfolio end-to-end: answer questions, relationship health, product adoption, renewal, upsell, and churn prevention. ALL of it is yours
Become the expert on your customers’ businesses: Understand how they use the product, where they get stuck, what features would transform their operations, and what drives them to stay or leave
Use AI tools (Claude, HubSpot automations, internal prompt libraries) to create leverage in your day-to-day so you spend 60%+ of your time on proactive, high-value work
Translate customer problems into product requirements and then work with engineering to build solutions using AI-assisted development. You don’t just file tickets; you learn to ship
Drive product feature adoption across your portfolio: identify which of our capabilities drive the most value per customer segment, build the adoption playbook, and execute it
Make your customers wildly successful: figure out what they actually need, use your brain to find creative solutions, ship things that make their lives easier, and think outside the box. This isn't about calling more, it is about being smart enough to make retention and expansion happen naturally
Build and refine playbooks that become the standard for the team. Your frontline experience shapes how everyone else operate

Requirements

What you’ll need

You enjoy talking to customers and fixing their problems. You will be proactively reaching out to your customers to ensure they are successful
An entrepreneurial mindset above all else you’ve started something, built something, or can’t stop thinking about building something. You see broken processes and fix them before anyone asks
Exceptional intellectual horsepower: you pick up new domains fast, connect dots others miss, and thrive in ambiguity. Degree from a top-tier university or equivalent proof that you can learn anything quickly
High energy and self-direction, you don’t wait for permission to move. You’ve thrived in high-performance environments: consulting, investment banking, high-growth startups, or similar
Bilingual: fluent English plus at least one of Spanish, French, German, or Italian. You’ll communicate across markets and build trust with customers in their language
A natural communicator who makes customers feel heard. You can explain a complex product issue to a frustrated customer AND translate that same issue into a clear requirement for an engineer
No technical background required. What matters is curiosity and tenacity, the kind of person who plays with AI prompts, discovers new ways to solve problems, and can't stop learning. We'll teach you the rest...
