Team Player: Comfortable operating in a lean, remote-first, high-trust environment. Able to independently drive work forward while collaborating across engineering, product, and security teams.

Education & Certifications: Bachelor's degree in Computer Science, Cybersecurity, or a related field preferred but not required. Relevant certifications such as OSCP, CSSLP, GWEB, or equivalent are a plus.

Ability to participate in a shared on-call rotation supporting production systems, including occasional after-hours, weekend, and holiday coverage, with responsibility for responding to critical alerts, coordinating escalations to restore service, and documenting issues to help prevent recurrence.
