Position Summary

As a Software Engineer, you will work with Product Managers and Designers to be the technical lead for a variety of challenging projects and build delightful 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 software engineer and team member. You will interact with one of the world's most vibrant communities of security researchers and hackers and use this experience to build delightful features and products for them and the thousands of companies who trust HackerOne with their cybersecurity posture.

As a Software Engineer, 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 spearhead 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.

Your Journey at HackerOne

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 - 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 sales, marketing, and various other functions, and you will have developed a good sense of cross-functional collaboration and communication.
Beyond 90 days, you will be a fully-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.

You are:

Tech-savvy and enjoy working with people and teams
A team builder who cultivates innovation and can drive cross-collaboration and execution of projects across multiple domains
Willing to learn from other Senior and Staff Software Engineers
