Linux Platform Security Leader – AI & Infrastructure

I'm working with a world leading quantitative hedge fund in New York looking to hire a deeply technical leader to help shape the security of its Linux platform as AI increasingly changes the infrastructure and workloads running across it.This isn't a policy or governance position.It's an engineering role for someone who understands Linux and systems security at a deep level, but also has the breadth and judgement to take an ambiguous security problem, understand what needs protecting, decide what should be built versus bought, and turn that into a practical engineering capability.The environment is heavily Linux-based, with AI workloads becoming an increasingly important part of the security challenge.We're interested in people who have experience across areas such as:Linux/OS/platform security and hardeningKernel and systems securityIsolation, sandboxing, containers and workload securityAuthentication, identity and privileged access on LinuxProtecting large-scale infrastructure and production environmentsSecurity engineering, automation and toolingAI/HPC infrastructure or securing AI workloadsBuilding or implementing security controls rather than simply defining policyThis is a leadership position, but it remains highly technical. You should still enjoy getting into the detail, investigating difficult problems, challenging assumptions and helping strong engineers determine how something should actually be built.I'm particularly interested in people who have spent their careers owning difficult technical problems end-to-end and can operate comfortably when there isn't an obvious answer or off-the-shelf product.New York City with 3 days in office and 2 remoteIf your background sits somewhere between Linux, systems engineering, platform security and AI infrastructure, I'd be interested in speaking.
