Position Summary

As a Software Engineer on the Enterprise Support team, you will work with Product Managers and Designers on 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.

You combine technological expertise, domain knowledge, and an unquestionable dedication to business objectives. You seek out new responsibilities and learning opportunities, and enjoy being part of a collaborative team.

At HackerOne, we embrace a Flexible Work approach, enabling our team members to work remotely while maintaining productivity and collaboration. We are seeking candidates located in London, and the surrounding metropolitan areas, to facilitate occasional in-person interactions as needed. While the position is primarily remote, there will be periodic in-person requirements to support team collaboration and foster stronger connections. This approach ensures flexibility while providing opportunities to build meaningful in-person relationships that strengthen our team and company culture.

• Your first day will start with a warm welcome and getting your tools set up to start!

• 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.
