Your Impact
Join a small team building the next generation of cybersecurity products from the ground up. Led by industry veterans with a proven track record of success - you will get to architect, build, and deliver hugely impactful products with this world class team. You will have the opportunity to grow your career and skills along with the company from the very start.
Role Overview
We're building a next-generation AI-native cybersecurity platform from the ground up. Unlike traditional SaaS products, our platform runs entirely within customer-controlled environments and processes massive volumes of security telemetry, system activity, and enterprise data.
We're looking for a frontend engineer who can own the user experience for complex security and operational workflows. This is not a typical consumer application role. You'll design and build interfaces that help security analysts investigate threats, navigate large-scale datasets, understand system behavior, and take action quickly. As one of the early frontend engineers, you'll have significant influence over product architecture, user experience, frontend infrastructure, and how AI is integrated into the product.
What You'll Do
- Design and build core user experiences for security investigation, detection, and response workflows
- Own frontend architecture across a large-scale enterprise application
- Partner closely with product, backend, AI, and infrastructure engineers to define new product capabilities
- Build highly performant interfaces for exploring and analyzing large datasets
- Develop advanced visualizations, dashboards, and investigation tools
- Leverage AI capabilities to improve analyst workflows and productivity
- Establish frontend engineering standards, patterns, and best practices
- Drive UI performance, scalability, and maintainability across the platform
Required Experience
- 5+ years building and shipping product frontend applications
- Deep expertise in React, TypeScript, and modern frontend architecture
- Experience designing and implementing complex workflows for expert users
- Strong product and UX instincts with the ability to make independent design decisions
- Experience building data-intensive applications, dashboards, developer tools, observability products, infrastructure software, or enterprise platforms
- Strong experience with frontend performance optimization, rendering performance, memory management, and profiling
- Experience working closely with designers or owning significant portions of the user experience directly
- Excellent communication and technical design skills
We offer competitive compensation and a comprehensive benefits package designed to support our employees’ health, well-being, and long-term success. The expected salary range for this position is $150,000 – $250,000 per year. Within this range, individual pay is determined based on job-related factors including skills, experience, qualifications, and internal equity. Most candidates can expect an offer within the range listed above. Your recruiter will provide additional details on compensation and benefits to qualified candidates during the hiring process.
