Role Overview

Our Red Cloak sensor team is looking for a Principal Software Engineer with deep knowledge of macOS/Darwin to drive the next-generation endpoint capabilities of our new product offerings, which you can explore here. You will work in a fast-paced, startup-like environment with an experienced, cross-functional team of software engineers, data scientists, and security experts to develop our next generation endpoint sensor that seamlessly integrates with our cloud-native security analytics platform.  If you love computer security and digging into complex engineering challenges, then we want your help securing human progress!

The ideal candidate will have a computer science background with an emphasis on operating systems and computer security.  Your focus will be on the macOS agent, but many features cut across OS subsystems such as collecting telemetry from processes, networking, and file systems. Your code will be used in a lean agent that delivers security by building on proven, pre-existing mechanisms inside macOS in order to minimize its footprint.  The agent has shared components across multiple platforms, so experience with Windows or Linux system-level development is also a plus. With a background in macOS kernel and driver development, we expect most will have extensive experience with C, but experience or interest with Golang is a strong plus and will be heavily utilized.  


  • Own feature development for our macOS sensor from design to delivery with high concurrency and reliability requirements and low/no impact to end users.  

  • Provide technical leadership on the architecture, strategy, and development of next generation threat detection and response capabilities.

  • Design and implement software with cross platform deliverables (macOS, Linux, Windows).

  • Recommend and develop new product concepts and capabilities.

  • Triage, reproduce, debug, and fix issues identified in the product.

  • Secure deployed code, update processes, and communication paths against potential attackers that aim to hijack highly privileged applications. 

  • Build tools to support team efficiency and contribute to test automation.

  • Lead projects efficiently while maximizing performance and minimizing costs.

  • Ensure high standards are being followed when it comes to design, coding quality, along with unit and component testing.

  • Work effectively on a geographically distributed team to deliver high quality software against aggressive schedules.   


  • Minimum of 3 years experience with C++ or Objective C with macOS

  • Minimum of 2 years System Level Development Or Kernel Development

  • Experience building production-grade, quality and secure software

  • Good understanding of security fundamentals like encryption, authentication

  • Strong networking concepts


  • Experience with Golang

  • Good understanding of x86/amd64 assembly.

  • Knowledge of malware analysis, vulnerability research, and exploit development.

  • Experience with product security areas including encryption, authentication, and other defensive techniques.

  • Familiarity with data science techniques or machine learning.

  • Familiarity of large scale data analysis pipelines, particularly the impact endpoint sensors have on downstream architecture and applications.
