From the employer
About LightSource
LightSource is building the next-generation operating system for Procurement. Sales has Salesforce. HR has Workday. Procurement is next. We build SaaS software that helps procurement leaders discover vendors, manage negotiations, and buy intelligently.
Our team is small but growing quickly, backed by top-tier investors and already winning enterprise customers. We're tackling a massive market filled with complex, high-impact problems. The team includes people who've helped build companies like Tesla, Waymo, McKinsey, and Google X. We hire exceptional people, move quickly, give direct feedback, expect excellence, and have a lot of fun doing it.
About the Role
We're looking for our first Growth & Demand Generation Manager — someone excited to help build the marketing function from the ground up. This isn't a typical demand gen role. You won't be handed a rigid playbook — you'll help write it. You'll work closely with leadership and our Account Executives to build the inbound and outbound marketing motion that fuels our next phase of growth.
The right person will combine analytical rigor, creative instincts, and a builder's mentality to drive pipeline from procurement leaders at some of the world's most interesting companies. You will be the architect of our demand engine and help set the foundation for how LightSource goes to market.
This is a full-time, onsite role at our office in downtown San Francisco (off Market St, steps from BART and Caltrain
