About the Role
As a Staff Frontend Engineer, you will own the frontend platform and experience that enables customers to visualize, understand, and act on complex security data with confidence.
This is a Staff+ caliber role: you’ve operated at least at Staff, Senior Staff, or Principal Frontend Engineer level at some point in your career, and you’re excited to set the technical direction for a brand-new platform. You will design the frontend infrastructure, build “golden” component libraries, and make the platform AI-friendly, all while continuing to ship customer-facing features.
You’ll combine deep architectural thinking with hands-on development, ensuring that our frontend stack is both elegant and resilient as we scale. Over time, you’ll help mentor other frontend engineers and we will build a team around the foundations you create.
What You’ll Do
- Define Frontend Architecture – Establish the core architecture and patterns for our web applications, laying the foundation for long-term scalability and performance.
- Build Golden Libraries & Platform – Create reusable component libraries and tooling that set the standard for quality and enable rapid, consistent development across the team.
- Build AI-Driven, User-Focused Features – While setting up core frontend infrastructure, design and deliver high-impact features that seamlessly integrate AI-powered capabilities, ensuring clarity, usability, and reliability for complex security workflows.
- Mentor and Influence – Serve as a mentor and technical leader for future frontend engineers; help us grow a team that values craftsmanship and excellence.
- Drive Engineering Craftsmanship – Uphold high standards of code quality, attention to detail, and thoughtful design. Balance speed with sustainable engineering practices.
About You
- Have operated at Staff+ level (Staff, Senior Staff, or Principal Frontend Engineer) at some point in your career.
- 5+ years of professional software engineering experience
- Deep expertise in React, TypeScript, and modern web application architecture.
- Strong background in frontend infrastructure—component libraries, build systems, state management, and performance optimization.
- Demonstrated ability to work autonomously, owning projects end-to-end with minimal oversight
- Exceptional attention to detail and a passion for engineering craftsmanship.
- Excellent collaboration and communication skills; thrive in fast-paced, high-impact environments.
