Site Reliability Engineer L5 - Open Connect
NetflixAbout the role
Netflix is one of the world's leading entertainment services, with 283 million paid memberships in over 190 countries enjoying TV series, films and games across a wide variety of genres and languages. Members can play, pause and resume watching as much as they want, anytime, anywhere, and can change their plans at any time.
How do you spark joy in hundreds of millions of people? It starts with a vision - that technology can give voice to stories around the world. In delivering those much-loved stories, Netflix is responsible for a significant portion of global internet traffic. To steward that responsibility, we work collaboratively with ISPs to deploy Open Connect, Netflix’s Content Delivery Network (CDN), our in-house custom-built network and server infrastructure responsible for delivering 100% of Netflix's video traffic.
In addition to streaming video delivery, Open Connect Appliances (OCAs) are ideally situated to also improve the latency between clients and the Netflix services running on AWS. The Open Connect Edge Accelerator is taking advantage of the highly geo-distributed nature of Open Connect to improve the quality of experience. It is the entry point for device and website traffic, putting it on the critical path to delivering and monitoring our product experiences.
We are seeking a seasoned Reliability Engineer with extensive experience in *nix, networking, data analysis, and large-scale service operations experience to design, scale, operate, automate, and analyze our globally distributed CDN, with a focus on the Edge Accelerator services. You will be working on reliability, resilience, performance, latency measurement, steering solutions, low-latency reverse proxy, failover mechanisms, protocol optimizations, and DDoS protection to name a few.
