Founding CS Engineer

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 knowledge base as the single source of truth, written for AI agents first Every issue you resolve teaches the system, so the next one is easier. You scale through systems, not headcount. Support is also the front edge of the customer experience. Done well, it's why customers stay and expand, which puts this role closer to revenue than a typical support seat. The bigger prize is the function itself. You define what AI-native post-sales looks like in production. Get it right and it becomes the model Lightfield scales on. This is a founding individual-contributor role. You own the work yourself today, with a clear path to leading the function and its team as it grows. You report to the Head of Customer Success and work with engineering, product, and customers every day.
