Deep, practical understanding of common vulnerability classes and how they are actually exploited - remote code execution, injection, cross-site scripting, SSRF, insecure deserialization, authentication and authorization bypasses, and denial-of-service and DDoS techniques - sufficient to assess real exploitability rather than defer to a scanner score. You will own the tooling that continuously tests our environment - bug bounty, agentic red team, CSPM, and vulnerability scanners - turn the output of those platforms into a prioritized, de-duplicated set of real issues, and drive them to verified closure with engineering and infrastructure teams.

Backstage LLC

Infrastructure Security Engineer

A single campus can behave like a dozen different organizations at the same time: central IT running enterprise applications, research computing and HPC teams, genomics and imaging cores, AI and machine learning labs competing for GPU time, an academic medical center with its own rules and its own budget, and faculty groups buying infrastructure directly with grant money. That environment rewards someone who can hold a lot of context at once, translate between very different audiences, and connect technology to the outcomes these institutions actually care about: time to result for researchers, compliance with sponsor and grant requirements, data that stays usable for a decade or more, and budgets that have to stretch further every year.
