At Netflix, we want to entertain the world and are constantly innovating on how entertainment is imagined, created, and delivered to a global audience. We currently stream content in more than 30 languages in 190 countries, topping over 250 million paid subscribers, and are expanding into new forms of entertainment such as gaming.
Open Connect (OC) is a critical group within Netflix that builds and manages a content delivery network (CDN) that delivers all of Netflix’s streaming video. In addition to streaming video, we work on projects within Netflix that leverage physical infrastructure, such as our Cloud Games and Live initiatives. According to a 2023 Sandvine report, data delivered by OC accounts for approximately 15% of all downstream traffic volume across the entire internet. Most of this traffic is delivered by our edge cache servers.
A small team of talented software engineers develops and maintains the operating system that runs the content caches. Because of the important role these caches serve, it is critical that they be both efficient and secure.
We are looking for a Security Software Engineer to architect and implement security features for the OC edge appliances and have the opportunity to directly impact a critical area of the business.

In this role, you will:

  • Collaborate with internal stakeholders to evaluate, design, and enhance the security posture of various OC server platforms.
  • Implement security enhancements using a variety of methods such as kernel and user-space development, configuration changes or leveraging hardware-based security features such as TPMs.
  • Assist developers in securely designing new features, providing guidance and support throughout the development process.
  • Act as a security liaison between OC and other organizations to ensure cohesive security strategies and practices.
  • Assist with incident response and analyze new security bugs to mitigate potential threats to our infrastructure.
  • Demonstrate versatility by learning and adapting to new architectures and features as they evolve.
  • Develop automated systems to test for vulnerabilities within our infrastructure.


  • Proven track record of architecting and implementing security features that meaningfully improve system security.
  • Experience using operating system execution environments such containers or virtual machines to enhance security
  • Success at partnering with others to improve the security posture through cross-functional changes.

You will be successful in this role if you:

  • Have the ability to define and self-manage cross-functional projects fueled by ambiguous questions.
  • Are a self-starter, curious, and not afraid to ask when in doubt.
  • Are a quick learner and excited about learning new technologies.
  • Advocate thoughtful collaboration, take pride in your work, and enjoy taking full ownership of projects from conception to production.

Nice to have:

  • Experience conducting penetration tests which found meaningful opportunities for improvement and identify security gaps.
  • Kernel development experience.
  • Experience successfully using TPMs/HSMs, trusted execution environments, and other hardware features.
  • Experience working on highly distributed systems.
