Network Systems Engineer

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 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).Network Systems Engineer Responsibilities

• Apply 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 infrastructure protocols and various other product teams to identify the highest impact issues in Meta product performance and efficiency.
• Perform competitive analysis and benchmarking for various Real Time Communication 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 Communication Service Providers to conduct technical due-diligence and provide technical support

Minimum Qualifications

• Background in communication systems and networking, with working level understanding of communication protocols across the CSP stack.
• Demonstrated experience in wireless networking technologies and standards (Wi-Fi and/or cellular).
• Experience in big data analysis – implement data swarm pipelines, analyze big datasets and automate.
• Demonstrated experience 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.
