Compensation : $145-170k Focus: Own Frontend (Admin + App), Support Backend When Needed About Knox Knox runs the largest Federal managed cloud, building and operating secure cloud and AI environments that support the U.S. government’s most critical missions — from national security and public safety to essential public services. Our customers rely on Knox to deploy production systems that meet the highest standards for security, reliability, and compliance. Work at Knox is high-impact and purpose-driven. The problems we solve are high-stakes, the expectations are high, and the results are visible. Speed, rigor, and trust matter here - because the environments we secure cannot fail. Your contributions are visible, your expertise is relied upon, and the impact of your work is immediate and measurable. We operate at federal scale, securing some of the most sensitive government environments in the country - because the systems we build must perform without fail.

The Role You'll own KnoxAI's entire frontend experience across two Nuxt 3 applications: the Admin interface (for Knox employees managing customer assessments) and the App interface (for customers and federal agencies reviewing findings and compliance posture). Your work will transform complex compliance data into intuitive, actionable interfaces that guide users through the FedRAMP authorization process. This role is perfect for a frontend specialist who wants full ownership of the user experience while occasionally diving into backend work to unblock features or improve API design. You'll work closely with the backend engineer and engineering manager to deliver a cohesive, polished product.
