Get to Know Us
Horizon3 http://Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. 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.
We 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.
About the Role
We are looking for a Staff Software Engineer to join our Core Front-End team and help shape the future of the user experience across the http://horizon3.ai/Horizon3 http://Horizon3.ai NodeZero platform.
This 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.
As 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.
This 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.
What You’ll Do
Technical Leadership & Architecture
- Drive front-end architecture decisions across the platform
- Design scalable, maintainable, and reusable UI systems and application patterns
- Lead large cross-functional initiatives involving multiple engineering teams
- Identify and reduce technical debt across shared front-end infrastructure
- Define and evolve front-end best practices, standards, and engineering guidelines
- Improve application reliability, observability, accessibility, and performance
- Partner with Design to improve consistency and usability across the product
- Help shape the long-term technical vision for the front-end platform
Platform & Developer Experience
- Improve shared tooling, component systems, and developer workflows
- Drive improvements in CI/CD pipelines, testing strategy, local development experience, and review environments
- Build reusable frameworks and abstractions that accelerate feature development across teams
- Collaborate on front-end performance optimization and platform-wide UX improvements
- Help standardize approaches across teams while balancing flexibility and autonomy
Engineering Execution
- Contribute hands-on production code in React and TypeScript
- Review code and provide high-quality technical feedback
- Collaborate closely with Product Managers, Designers, and Engineers throughout the development lifecycle
- Participate in technical planning, roadmap discussions, and architecture reviews
- Help unblock teams and provide technical guidance for complex implementation challenges
Mentorship & Influence
- Mentor engineers across multiple teams
- Raise the engineering bar through technical leadership and collaboration
- Influence engineering culture, review quality, and development practices
- Act as a trusted technical partner for both engineering and product leadership
- Help grow future technical leaders and architects within the organization
What We’re Looking For
Required Qualifications
- 8+ years of experience building modern web applications used in production at scale
- Deep expertise in JavaScript/TypeScript and React
- Strong understanding of modern front-end architecture and application design
- Experience leading large technical initiatives across multiple teams
- Experience designing reusable component systems and scalable UI patterns
- Strong knowledge of application state management, asynchronous data flows, and API integration patterns
- Experience improving front-end performance, reliability, and maintainability
- Strong debugging and problem-solving skills across both front-end and full-stack systems
- Excellent written and verbal communication skills
- Experience mentoring engineers and influencing technical direction
- Ability to thrive in fast-moving, highly collaborative environments with evolving priorities
Preferred Qualifications
- Experience building platforms, frameworks, or shared engineering infrastructure
- Experience with GraphQL and modern API-driven architectures
- Experience working in a monorepo environment
- Experience with modern build systems and tooling
- Familiarity with cloud-native environments and AWS
- Experience with observability and monitoring tools such as Datadog
- Experience working closely with Product Design and Design Systems
- Startup experience, particularly in high-growth environments
- Cybersecurity or offensive security domain experience
- Experience leveraging AI-assisted development workflows and engineering tooling
Our Front-End Stack
- React
- TypeScript
- GraphQL
- GitLab
- AWS
- Modern CI/CD pipelines
- Design systems and shared component libraries
What Success Looks Like
- Engineering teams can move faster because of the systems and foundations you build
- Front-end experiences become more scalable, consistent, and maintainable
- Architectural decisions improve long-term product velocity
- Shared standards and tooling reduce friction across teams
- Engineers across the organization seek your guidance for complex technical challenges
