Senior Frontend Engineer — AI Product, Impactful

About the company

We're partnering with a venture-backed AI infrastructure company building tools that help teams develop, test, and deploy reliable machine learning systems. Their product is used by both fast-growing startups and large enterprise customers to ensure AI behaves consistently, safely, and at scale.

The team is early, highly technical, and product-focused. Founders have deep experience building complex AI systems and are now investing heavily in the frontend and product experience to support enterprise-grade use cases.
