Are you a builder with deep expertise in Linux internals and Identity architecture? An elite technology-driven firm is seeking a Senior Systems Engineer to take ownership of its critical authentication platforms. This is not a standard maintenance role; it is an opportunity to architect the bridge between complex legacy infrastructure and modern identity security in a high-performance computing environment. 
 
Responsibilities: 
 
Identity Architecture Modernization &ndash; Redesign and modernize the firm&rsquo;s internal PKI and authentication services, bridging the gap between Kerberos/Active Directory and modern OIDC/OAuth standards. 
 
Linux Security Engineering &ndash; Secure the global Linux fleet by designing solutions for insider risk monitoring, privileged access (PAM), and process-level identity. 
 
Deep-dive Troubleshooting &ndash; Go beyond standard admin tasks to debug complex OS, kernel, and filesystem issues using advanced diagnostic tools (strace, perf, eBPF). 
 
Tooling &amp; Automation &ndash; Design and build proprietary security tooling and automation frameworks from scratch using Python. 
 
 
What you&rsquo;ll need: 
 
<ul><li>10+ years of security focused systems engineering experience.
</li><li>You possess the rare combination of deep Linux expertise AND architectural knowledge of Identity protocols (Kerberos, PKI, OIDC).
</li><li>Linux internals - you understand the OS at a deep level (Kernel, Systemd, Filesystems) and know how to harden it.
</li><li>You don't just use vendor tools; you write code (Python) to solve unique scalability and security challenges.
</li><li>You can effectively communicate complex architectural trade-offs to both software engineers and senior leadership. 
</li></ul> 
 
Why join them? 
 
<ul><li>Solve the hardest problems by working on the complex intersection of legacy scale and modern security.
</li><li>Join a team that values first-principles thinking and academic rigor.
</li><li>Take direct architectural ownership of the systems that secure the firm's core assets.
</li><li>If you&rsquo;re a visionary engineer who loves rabbit holes and building foundational systems, we&rsquo;d love to hear from you!</li></ul></div></div>
