Software Engineer III, Payments

Remote Location: Austin, TX or Washington DC

Position Summary

This software engineering position will reside on a Payments Engineering Team. The Payments Engineering Team’s primary mission is to enable HackerOne to move money between customers and hackers in a compliant, flexible, and safe manner. This role primarily focuses on the back-end but having some front-end experience would be helpful for the team.

In the near future, the team will expand their domain ownership and start maintaining and developing other platform components of the HackerOne platform. You'll be expected to work on backend-heavy payment processing code and touch the frontend occasionally. Ideally, you'll have a strong foundation in either, but want to learn the other as well.

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 Austin, TX or Washington DC, 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.
