Position Summary

As a Software Engineer IV, you will work with Product Managers and Designers to be the lead for a variety of challenging projects and build features and products for our community and the thousands of companies that trust HackerOne with their cybersecurity posture. When you are not leading a project, you are a collaborative and effective senior engineer and team member.

You combine broad technological expertise, deep domain knowledge, and an unquestionable dedication to business objectives as you intersect with the engineering organization. You seek leadership responsibilities, identify and drive new initiatives, and make systematic improvements to technical weaknesses they find in their squad’s codebases, as well as in shared codebases across the company.

What You Will Do

• Your first month will be spent getting to know our company and your fellow HackerOnies through our well-organized and fun onboarding process called H.A.T.C.H.

• By day 90 you’ll have impressed your colleagues with your technical contributions, and you’ll have earned trust and credibility within your squad and the whole Engineering team, presenting your progress during our review/demo sessions.

• Your experience from here is yours to own. You could lead an important new project and work hand-in-hand with our principal engineer and designers. You could innovate during a Hack Week, by building something amazing that solves a problem for another team.
