About the Role  

We're looking for a Principal Frontend Engineer to own and evolve the systems that power VulnCheck's user-facing products. This is a hands-on role where you'll drive the direction of the product UI and collaborate closely with your teammates 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: design, architecture, development, and continuous improvement


• Drive frontend direction—establishing patterns, component systems, and design standards


• Write clean, maintainable code across the stack (frontend-first, with backend context as needed)


• Partner closely with Product 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


• Support Marketing and other teams across the company as relates to web frontend needs

What You'll Bring

• 5+ years of experience building and shipping production web platforms


• Strong proficiency in modern frontend frameworks (Nuxt/Vue 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 Product 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


• Background in cybersecurity or technical data products


• Experience in high-growth or startup environments
