Job Title:
Staff Front End Engineer – RangeGPT Platform Location:
Remote (Boulder/Denver, CO) Department:
Engineering Reports to:
Chief Engineer Compensation:
$165,000–$185,000, commensurate with experience Benefits:
Comprehensive benefits including medical, dental, and vision insurance, 401(k) with company match, HSA/FSA options, life insurance, unlimited PTO, and paid holidays. Job Summary: Circadence is hiring a Staff Front End Engineer to lead the development of the RangeGPT user interface—a cutting-edge cyber range design and analysis tool that combines a WYSIWYG canvas editor with LLM-driven agentic workflows. You will be responsible for building and owning the front end of RangeGPT V1.0, creating a visual system that enables cybersecurity professionals to design, deploy, and analyze complex infrastructure with ease using drag-and-drop and other intuitive interfaces. This role requires an advanced engineer with deep front-end expertise and a strong product sense. You will excel if you have experience building modern, maintainable React systems, enjoy solving UI challenges in graph-based design tools, and want to influence the future of usable AI tooling. Key Responsibilities: Architect and evolve the front-end codebase using React, TypeScript, and modern libraries (e.g., Next.js, React Router, MUI/Tailwind). Lead the design and implementation of scalable component frameworks, UI state models, and interaction patterns for RangeGPT's WYSIWYG interface. Collaborate with AI, backend, and product teams to translate agentic workflows and LLM outputs into intuitive visual interactions. Build interfaces that support real-time topology visualization, interactive assistants, and deployment feedback loops. Develop algorithms for auto-layout mechanisms for canvas-based visual components. Promote frontend best practices in testing, performance optimization, accessibility, and maintainability. Own and guide technical decisions related to client-side architecture, tooling, and delivery pipelines (CI/CD, bundling, testing). Mentor and support other engineers to improve team velocity and code quality. Stay current with frontend and AI UX trends and evaluate new technologies for suitability. Required Qualifications: 7+ years of professional experience in front-end or full-stack roles with a focus on UI, including senior-level positions. Expertise in React + TypeScript, with experience in architecting complex SPAs. Experience owning frontend frameworks and design systems used across teams. Strong knowledge of UI testing strategies and tools like Playwright. Experience building visual or diagram-based tools, real-time collaborative apps, or agent-integrated interfaces. Familiarity with API design, async orchestration, and integrating LLM-driven workflows. Comfort with containerized development (Docker) and frontend CI/CD workflows. Additional Qualifications: Experience with canvas-based editors, node graph libraries like XYFlow or ReactFlow, or low-code/no-code platforms. Knowledge of LangGraph, function/tool calling, or semantic retrieval systems. Background in cybersecurity, DevOps automation, or infrastructure-as-code platforms. Familiarity with MCP (Model Context Protocol) or related cyber range orchestration systems. Why Circadence? Join Circadence to shape the future of cybersecurity training by working with a passionate team building a platform used to train security professionals, enterprise defenders, and future cyber leaders. We value innovation, autonomy, and purpose—be part of a fast-growing team of AI researchers, software engineers, and curriculum designers making a difference in cybersecurity training.
