Principal Software Engineer | Front End at ExtraHop

We are ExtraHop. We're on a mission to provide security teams with the intelligence they need to confront and stop advanced threats like supply chain attacks, zero day exploits, and ransomware attacks. Cyber attackers still have the advantage. We’re taking it back with creativity, intellectual curiosity, and a sense of humor. Are you ready to help us reclaim the upper hand? 

ExtraHop R&D supports fully-flexible work options that includes full time onsite, hybrid, and fully remote working arrangements. With the exception of a few roles that require physical access, we believe in supporting you in making the choice that works best for you and makes the team successful.

We’re looking for a Principal Software Engineer interested in building industrial-strength applications with maintainable code and clean user experiences.

Our team is responsible for the large-scale web app serving as the primary interface for our company’s product. We build data-dense visualizations and deep-dive investigation interfaces for a full range of security & performance users, from entry-level to expert.

We embrace strongly-typed TypeScript and functional paradigms. We tackle tech debt in a timely manner. We give peer code reviews to keep our quality bar high (and we use tools like Prettier and ESLint to automate the pedantic bits).

We offer an engaging and innovative environment in which people are encouraged and supported to collaborate on industry-leading technology and create a world-class engineering team, while they develop and enrich their individual growth. And we’re doing it with creativity, intellectual curiosity, and a sense of humor.
