Position Summary

As a Senior Detection & Response Security Engineer, you will play a critical role in strengthening HackerOne’s security posture. You’ll design and implement cutting-edge detection strategies, automate response workflows, and lead incident response efforts to safeguard our systems and data.

Your focus will be on understanding our detection and response capabilities and developing recommendations to enhance them.

  • Evaluating potential detection techniques and tools and using them to create useful, actionable, high signal alerts. 

  • Developing automation and improving existing tooling and alerting to minimize alert fatigue and maximize effective incident response.

  • Collaborating will be key as you will work closely with IT, Engineering, Support and other teams across the company.

• You will play a vital role in managing security incidents, from assembling the response team to organizing and leading blameless retrospectives. You'll also help develop clear response processes for various types of incidents and playbooks for various alerts generated by our tools.
