About The Position

As an Infrastructure Engineer IC4, you will contribute to building and operating the infrastructure that supports the HackerOne platform and the thousands of companies that rely on us to manage their security posture.
You are a strong individual contributor and collaborative team member with solid domain expertise in cloud infrastructure and reliability. You work effectively within your squad, take ownership of projects, and help improve the reliability, security, and scalability of our systems. You partner closely with application engineers and other stakeholders to deliver pragmatic, secure solutions.
You understand how to design and operate highly available cloud systems and apply best practices for reliability, observability, and security. You work cross-functionally with guidance, communicate clearly with stakeholders, and approach problems with a service-oriented mindset.
At HackerOne, we embrace a Flexible Work approach that gives us the freedom to do our best work while also fostering the connections and community that make us stronger. Reflecting this philosophy, this is a remote role targeted for candidates within ~50 miles of Boston, Austin, or Washington DC. We believe this balance of proximity and flexibility gives Hackeronies the chance to occasionally come together – fostering collaboration, connection, and in-person moments that enrich our culture – while still preserving the benefits of remote work.
