Get to Know Us
Horizon3 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 Horizon3 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 DoTechnical 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
