In this high-ownership role, you will build Mission Control - the interfaces and APIs our Fortune 500 customers use to deploy, monitor, and control AI security agents.

Responsibilities

You will set the technical direction for Mission Control's UI across the full stack: React front end, the APIs behind it, and the automation that deploys and tests your work.

You will be the integrator across product, design, and backend - bringing Figma designs to life, surfacing gaps early, and proactively unblocking others.

You will build the experience that turns powerful agents into a product customers trust at enterprise scale: transparent, controllable, and dependable 24/7/365. The environment is fast-paced, rapidly scaling, and highly collaborative across multiple engineering and product teams. The opportunity for transformational impact is significant.

Excellent communication and leadership skills, including managing stakeholders and mentoring other engineers. A proactive "get it done" attitude and willingness to move forward through uncertainty.
