Lead Endpoint Security Engineer - Own the Code That Protects Millions, Invisibly

CareerXperts Consulting · That, India

This is not a job. It's a mandate to architect the last line of defense.

We're building the core endpoint agent that stands between attackers and the enterprise - operating silently at the deepest layer of the OS, where most engineers never go and even fewer can lead.

This is deep systems work. Real ownership. Zero hand-holding.

What you'll own:

• Architect and lead a cross-platform endpoint agent across Windows and macOS - end to end, from design to production.
• Drive traffic steering and packet interception at the kernel/network layer - routing traffic through a transparent proxy, invisibly and reliably.
• Command Windows Filtering Platform (WFP) and Apple's Network Extensions framework at an architectural level.
• Own the full Secure Development Lifecycle - threat modeling, secure design, security testing, release sign-off.
• Apply deep cryptographic fundamentals 0 PKI, HSM, TEE, digital signatures - as core infrastructure, not afterthoughts.
• Diagnose the unsolvable - crashes, deadlocks, memory faults, performance regressions at OS-internals depth.
• Lead and grow a team of endpoint engineers - setting technical direction, raising the bar, shipping without excuses.

What you bring:

• 8–14 years building production-grade, system-level or endpoint software.
• Deep OS-internals mastery - processes, memory, scheduling, file systems, kernel subsystems.
• Proven ownership of a product from requirements through delivery.
• Prior experience leading engineers, not just writing code.
• Strong grip on network protocols - HTTP, HTTPS, TLS/SSL.
• AI-fluent - you use modern tools to move faster, not slower.
• Startup DNA - high ownership, high velocity, zero excuses.

If you've built the plumbing security products run on - and you carry the rare execution DNA to lead it - this seat is yours to claim. Reach out:
