VulnCheck is transforming vulnerability intelligence by helping security teams act faster and with more confidence. Our platform delivers early, high-quality exploit intelligence, deep asset correlation, and contextual insights to help organizations stay ahead of emerging threats.

About the Role 

We're looking for a Frontend Engineer to own and evolve the systems that power VulnCheck's user-facing products—our web platform and marketing website. This is a hands-on role where you'll drive the direction of the product UI, maintain and improve the website, and collaborate closely with Product to shape how customers experience VulnCheck's intelligence. Although this is a 100% remote role, candidates must be located in Massachusetts, Maryland, or Greater Austin, TX.

What You'll Do

• Own the product UI end-to-end: architecture, development, and continuous improvement
• Lead frontend direction—establishing patterns, component systems, and design standards
• Build and maintain the marketing website, balancing speed with quality
• Write clean, maintainable code across the stack (frontend-first, with backend context as needed)
• Partner closely with Product and Design to translate requirements into polished user experiences
• Improve performance, accessibility, and reliability of customer-facing interfaces
• Participate in technical design discussions and contribute to frontend architecture decisions
• Debug and resolve production UI issues with durable, thoughtful solutions
• Mentor other engineers on frontend best practices and contribute to engineering culture

What You'll Bring

• 5+ years of experience building and shipping production web applications
• Background in cybersecurity or technical data products
• Strong proficiency in modern frontend frameworks (React preferred)
• Full-stack competence—comfortable working across the codebase, backend experience a plus
• Experience owning a product UI or web property end-to-end
• Solid understanding of web performance, accessibility, and browser compatibility
• Ability to work closely with designers and translate visual direction into high-quality implementations
• Strong ownership mindset—you notice what's broken and fix it without being asked
• Clear communication and ability to collaborate cross-functionally

Preferred Qualifications

• Experience in B2B SaaS or developer-facing products
• Familiarity with design systems or component library ownership
• Experience in high-growth or startup environments
