About Us

WitnessAI enables safe and effective adoption of enterprise AI, through security and governance guardrails for public and private LLMs. The WitnessAI Secure AI Enablement Platform provides visibility of employee AI use, control of that use via AI-oriented policy, and protection of that use via data and topic security. We're looking for a talented Senior Frontend Engineer to help build and maintain our web applications. If you’re passionate about development and enjoy working on high-performance, scalable systems, we’d love to have you on our team.

Role Overview

We are looking for a Senior Frontend Engineer who thrives at the intersection of product and engineering. In this role, you'll play a key part in shaping user experiences by building scalable, high-quality applications that drive real customer impact. We're looking for someone who approaches problems with a product mindset, has a deep understanding of the modern JavaScript and TypeScript ecosystem, and is passionate about owning features from concept to delivery.

We primarily build in full-stack TypeScript (react-router formally known as remix), so experience across the stack is a strong plus—especially when it comes to designing and working with APIs. You'll collaborate closely with product, design, and backend teams, but we also value engineers who can independently lead and drive initiatives across the stack when needed.
