About Light. Light exists to replace factory-era ERPs with software that feels alive. Our Smart Financial Platform gives modern, global companies superpowers—automated accounting, real-time reporting, and financial flows that move at the speed of the business.
We build with our customers, ship fast, and obsess over craft. In a short time, Light has gone from idea to the operating core for leading companies like Lovable, Legora, and Keyshot. People don’t just use Light—they enjoy it.
We’re an early team defining a new software category. Think engineers who love debits and credits, designers who care about reconciliation states, and operators who treat finance as a product. If you’re excited to modernize how the world runs money—one workflow at a time—you’re in the right place.
Backed by world-class investors and advised by industry titans, we’re building category-defining products with the freedom to ship ambitiously and own outcomes.
Come help us make Light the global default for next-gen finance.
The AI Platform Engineer Role You will join the Foundation Team , the force multiplier for our entire engineering organization. Our mandate is to "build the factory that builds the product." As a Senior AI Platform Engineer, you will not just be tuning prompts, you will be architecting the internal "AI Engine" that powers every AI feature at Light.
We are looking for a systems thinker who is obsessed with the bleeding edge of AI but grounded in the reality of production engineering. You will help us move beyond simple API wrappers to build a robust Agent Runtime , define our internal standards for AI reliability, and ensure our product teams can ship deterministic, high-quality AI features in days rather than weeks.
