Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs.\nWe are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, \"checkbox\" security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results.\nAbout the Role\nWe are looking for a Staff Software Engineer to join our Core Front-End team and help shape the future of the user experience across theHorizon3 NodeZero platform.\nThis is not a traditional feature team role. The Core Front-End team operates as a central front-end architecture and enablement group responsible for driving the long-term scalability, consistency, performance, and usability of the NodeZero platform. You will work across multiple product areas and partner closely with Product, Design, Front-End, Back-End, Platform, and Security Engineering teams to define and implement modern user experiences at scale.\nAs a Staff Engineer, you will lead complex technical initiatives that span multiple teams and systems. You will help define architectural direction, establish engineering standards, improve developer workflows, and guide the evolution of our front-end platform and design system. You will also play a key role in mentoring engineers, influencing technical strategy, and accelerating engineering effectiveness across the organization.\nThis role is ideal for engineers who enjoy solving ambiguous problems, influencing technical direction beyond their immediate team, and building systems that enable other engineers to move faster.\nWhat You’ll Do\nTechnical Leadership & Architecture\nDrive front-end architecture decisions across the platform\n\nDesign scalable, maintainable, and reusable UI systems and application patterns\n\nLead large cross-functional initiatives involving multiple engineering teams\n\nIdentify and reduce technical debt across shared front-end infrastructure\n\nDefine and evolve front-end best practices, standards, and engineering guidelines\n\nImprove application reliability, observability, accessibility, and performance\n\nPartner with Design to improve consistency and usability across the product\n\nHelp shape the long-term technical vision for the front-end platform\n\nPlatform & Developer Experience\nImprove shared tooling, component systems, and developer workflows\n\nDrive improvements in CI/CD pipelines, testing strategy, local development experience, and review environments\n\nBuild reusable frameworks and abstractions that accelerate feature development across teams\n\nCollaborate on front-end performance optimization and platform-wide UX improvements\n\nHelp standardize approaches across teams while balancing flexibility and autonomy\n\nEngineering Execution\nContribute hands-on production code in React and TypeScript\n\nReview code and provide high-quality technical feedback\n\nCollaborate closely with Product Managers, Designers, and Engineers throughout the development lifecycle\n\nParticipate in technical planning, roadmap discussions, and architecture reviews\n\nHelp unblock teams and provide technical guidance for complex implementation challenges\n\nMentorship & Influence\nMentor engineers across multiple teams\n\nRaise the engineering bar through technical leadership and collaboration\n\nInfluence engineering culture, review quality, and development practices\n\nAct as a trusted technical partner for both engineering and product leadership\n\nHelp grow future technical leaders and architects within the organization\n\nWhat We’re Looking For\nRequired Qualifications\n8+ years of experience building modern web applications used in production at scale\n\nDeep expertise in JavaScript/TypeScript and React\n\nStrong understanding of modern front-end architecture and application design\n\nExperience leading large technical initiatives across multiple teams\n\nExperience designing reusable component systems and scalable UI patterns\n\nStrong knowledge of application state management, asynchronous data flows, and API integration patterns\n\nExperience improving front-end performance, reliability, and maintainability\n\nStrong debugging and problem-solving skills across both front-end and full-stack systems\n\nExcellent written and verbal communication skills\n\nExperience mentoring engineers and influencing technical direction\n\nAbility to thrive in fast-moving, highly collaborative environments with evolving priorities\n\nPreferred Qualifications\nExperience building platforms, frameworks, or shared engineering infrastructure\n\nExperience with GraphQL and modern API-driven architectures\n\nExperience working in a monorepo environment\n\nExperience with modern build systems and tooling\n\nFamiliarity with cloud-native environments and AWS\n\nExperience with observability and monitoring tools such as Datadog\n\nExperience working closely with Product Design and Design Systems\n\nStartup experience, particularly in high-growth environments\n\nCybersecurity or offensive security domain experience\n\nExperience leveraging AI-assisted development workflows and engineering tooling\n\nOur Front-End Stack\nReact\n\nTypeScript\n\nGraphQL\n\nGitLab\n\nAWS\n\nModern CI/CD pipelines\n\nDesign systems and shared component libraries\n\nWhat Success Looks Like\nEngineering teams can move faster because of the systems and foundations you build\n\nFront-end experiences become more scalable, consistent, and maintainable\n\nArchitectural decisions improve long-term product velocity\n\nShared standards and tooling reduce friction across teams\n\nEngineers across the organization seek your guidance for complex technical challenges\n\nYou help shape the future direction of the platform, not just individual features\n\nTravel Required\nWe are a fully remote company, and this job may require up to 5% of travel to be successful.\nCompensation and Values\nAt Horizon3, we believe that our people are our greatest asset, and our compensation philosophy reflects this core value.
