As a Vulnerability Researcher, you'll build first-principles understanding of the technologies and systems you investigate, then go looking for what's wrong with them: the flawed assumptions baked into established paradigms, the gap between how a system is meant to behave and how it actually behaves, and the novel vulnerabilities and exploitation techniques no one has named yet. This is hands-on, deep technical work - reverse-engineering, breaking, and finding what's exploitable before an attacker does.
What you will Do:

Hunt for what established security paradigms miss: flawed assumptions, gaps between specified and actual behavior, and novel vulnerability classes and exploitation techniques that don't yet have names.

Reverse-engineer and deeply understand systems, protocols, and architectures at the implementation level - developing a precise understanding of how they actually work, rather than what their designers intended.

Develop hypotheses and convert them into working proof-of-concept exploits that demonstrate real-world risk before attackers do.

Own research threads end-to-end, from an early exploration, developing and following hunches all the way through to a proof of concept, responsible disclosure or publication, following the evidence wherever it leads without waiting for a defined playbook.

Ground understanding of exploitability in attacker reality - when research surfaces findings relevant to how the platform models identity attack surface across human and non-human identities, bring that signal in.

Promote standing in the security community through original research, CVEs, and technical thought leadership that advances the field and earns trust on its merits.
