Network Systems Engineer

Meta Platforms, Inc.•Menlo Park, CA

About The Position

All of Meta's traffic goes over third-party Communications Service Provider (CSP) networks before it reaches Meta's users. This portion of the network which sits between Meta infrastructure and our end users has a direct impact on our users' product experience and Meta's revenue. The scope of the problem is significant since CSP networks come in a large variety of last mile access to home technologies, including fixed (fiber, cable, copper, FWA, satellite), cellular (3G/4G/5G) and in-home wireless access (WiFi 5/6/7). The market is bifurcated by a large number of infra OEMs and Service Providers on regional and country level. Many of them move slowly. Limited visibility into third-party networks and privacy/policy constraints with respect to personally identifiable information (PII) introduce unique challenges. All of this impedes scalability of solutions that require CSP collaboration and increases complexity for internal product interventions. The Communications Systems & Ecosystems team brings extensive technical knowledge of CSP infrastructure and unique engineering skills to develop solutions that enable Meta Family of Apps (FoA) teams to improve performance, competitive advantage and efficiency over a variety of CSP network conditions, either through direct internal optimizations with prod teams (i.e., control your own destiny), or engaging with external engineering teams on CSP partner side for joint solutions (i.e., collaboration with industry).

Requirements

Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
Extensive background in communication systems and networking, with working level understanding of communication protocols across the CSP stack
In-depth understanding of Wireless networking technologies and standards (Wi-Fi and/or cellular)
Expertise in big data analysis - implement data swarm pipelines, analyze big datasets and automate
Expertise in evaluating and optimizing network performance with multiple skills ranging in data and signal processing, statistical methodologies, analytics, simulation, emulation, lab setups, field trials, and prototyping for feasibility and trade-off analysis
Proficiency with one or more of the following programming or scripting languages: Matlab, Python, C/C++, ns-3
M.Sc. or Ph.D. in EE, Computer Science or Data Science with minimum 6+ years of industry experience

Nice To Haves

Understanding of WebRTC, QUIC, HTTP2
Hands-on experience with Network debugging tools (e.g. packet sniffers, protocol analyzers)
Background in AI/ML/LLMs
Experience with developing firmware or software for production

Responsibilities

Apply extensive knowledge of wired and wireless networking to characterize and optimize features/algorithms in the Meta product stack to elevate user experience
Partner closely with engineering teams on Whatsapp calling, Traffic infra protocols and various other Family of Apps product teams to identify the highest impact issues in Meta product performance and efficiency
Perform competitive analysis and benchmarking for various RTC and video apps in lab and field
Develop actionable problem statements to reproduce, narrow down and root cause issues, and engage with partner teams on developing and testing solutions
Modify Meta production software either as a development branch for proof of concept development, or for the final implementation
Work closely with Ecosystem, Telco Partnership and Policy teams to structure programs with CSPs to conduct technical due-diligence and provide technical support
