About the role

We're looking for a Senior Product Marketing Manager — someone who can own how LightSource is understood in market and help build the PMM function from the ground up. This isn't a typical PMM role. You won't inherit someone else's positioning — you'll sharpen and own it. You'll work closely with product, sales, and leadership to craft messaging that lands with procurement and operations leaders, and produce the content that puts those ideas in front of the right people.

More about this role

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.
