Full Job Description

ABOUT LIGHTFIELD Lightfield is an AI-native CRM that assembles itself from your email, calendar, and meetings. It captures every interaction and turns it into organized context: accounts, tasks, follow-ups, and insights, so nothing slips through the cracks. We’re rethinking CRM from first principles. Instead of forcing teams to maintain rigid systems, Lightfield learns from how companies actually work, adapting, automating, and surfacing the insight that drives growth. We’re building the CRM platform we always wished existed: fast, intelligent, and genuinely helpful. We are backed by Greylock, Lightspeed, and Coatue, and our founders previously built Tome, a generative AI presentation product used by over 25 million people. Before Lightfield, our team worked on Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce. ABOUT THE ROLE We've shipped a product founders love. Nearly 2,000 companies have signed up since our November launch. And our customers build inside Lightfield: writing skills, designing automations, wiring our workflows into how they operate. That changes what support has to be. Every Support and Customer Success team in software wants the same thing: keep customers successful as they scale, without adding a body for every cohort. Most can't get there. They bolt AI onto tools built for manual work, and the seams show. Lightfield starts from the other end. The product is the AI engine, the same one our customers use to run their own go-to-market. So we can build what almost no one can: a post-sales function that's AI-native from the ground up, running on the product itself. We're hiring our first CS Engineer to build it. In the near term, you own Support and Customer Success outright. You're in the queue every day handling real tickets, and you build the systems that make it better: - Health scoring that flags risk before a renewal slips - Onboarding that runs itself - A front-line agent that handles the first wave of questions - A know
