Founding Product Marketing Manager

LightSource is the next-generation operating system for procurement. We build SaaS software for procurement leaders—the people responsible for managing suppliers and vendors.

Sales has Salesforce. HR has Workday. And now, finally, procurement has LightSource.

Think of us like a CRM, but instead of helping sales professionals find customers, we help procurement managers find vendors, manage negotiations, and buy intelligently.

Our team is small but growing quickly. We’re (exceedingly) well-funded by top-tier investors and already punching well above our weight-class with enterprise logos—despite having no dedicated sales professionals on our team to date.

We’re a driven, high-caliber team who’ve helped build some of the world’s most innovative companies (Tesla, Waymo, McKinsey, and Google X). Now we’re tackling one of the biggest and thorniest problems in enterprise.

Our team is small, but our ambitions are big. We only hire the best and are obsessed with learning every day—while having a lot of fun along the way.
