Director of Product

Lightyear is building the operating system for enterprise AI consumption: the layer that measures, governs and optimizes how organizations spend on tokens, models and agents. We are hiring a Director of Product, our founding product lead, to own what we build, in what order, and for whom. The product is modular- Lightyear's basic offering gives finance and engineering leaders attribution of AI spend by developer, model, team and project, empowering them to optimize usage and spend. Advanced tiers are deployed directly into an enterprise's operations, optimizing model routing and budget in real time. This is a 0-to-1 role. You will define the MVP, recruit and run design partners, set the methodology for attributing token spend and connecting it to work outcomes, carry the technical half of the sale with FinOps leads, platform and AI engineering teams, finance, and the CTOs and heads of AI who must justify the AI budget, and build the product function from scratch. You should be as comfortable debating gateway architecture and telemetry schemas with engineers as you are sitting across from a CFO explaining the return on their AI spend. You will be the founding product lead and first product hire, with a mandate to hire and lead the product and design team as Lightyear grows.
