mac OS Endpoint Security Engineer - SDE2

Role Overview

We're hiring an SDE2 mac OS Developer to own endpoint security on mac OS for our cybersecurity platform. You'll work directly with the founders, no layers in between, building deep, kernel-aware protection that actually ships and actually matters. If you like getting your hands dirty in mac OS internals and want your work to have real impact from day one, this is that role.

What You'll Do

Build and ship mac OS endpoint security agents in Objective-C, Swift, and C++. Work directly with the mac OS Endpoint Security Framework for real-time threat detection. Dig into mac OS user space and internals to solve hard problems, not just patch symptoms.

Debug at the kernel level and reverse-engineer kernel-space code when needed. Bring security fundamentals (encryption, network security, firewalls) into everything you build. Work closely with product and engineering to turn security requirements into shipped features, fast.

Talk tradeoffs directly with founders. No committees, no red tape. What We're Looking For





2+ years building on mac OS with Objective-C, Swift, and C++. Real depth in mac OS user space and internals, not surface-level familiarity. Hands-on experience with the mac OS Endpoint Security Framework. Comfortable with kernel-level debugging and reverse engineering kernel-space code.

Understands core security concepts: encryption, network security, firewalls. Communicates clearly and thinks about the business impact of what you build, not just the code. Thrives in a small, rapid-moving team where you own outcomes, not just tasks. What's In It For You

Ship code that runs at the kernel level and protects real companies from day one. Work shoulder-to-shoulder with the founders on the endpoint security roadmap. Small team, high trust, real ownership. What you build is what ships. Grow into a senior/lead engineering role as we scale, not stuck in a fixed lane.
