Senior Software Engineer

Remote Location: Austin, TX and 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; 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.

What You Will Do

• Your day will start with a warm welcome online and get your tools to start!

• Your first 30 days will be focusing on getting to know our HackerOnies. You will join your new squad and be onboarded to engineering - get to learn the technology stack (Ruby on Rails + GraphQL + ReactJS + many more).

• Within 60 days, you will have committed a bunch of code to our repositories and will start developing a knack for being a fast and effective software engineer on our codebase.

• Within 90 days, you will start getting ready to lead your first project. You will have branched out and talked to Finance, Verification & Risk Monitoring, Customer Support, and various other functions, and developed a good sense of cross-functional collaboration and communication.

• Beyond 90 days, you will be a full-fledged software engineer. By that time, you will be able to understand the business value of our products and features and the needs of our customers, and you can translate feature requests into simple but robust engineering (or non-engineering) solutions.
