Edge sites face tight space, power, and hardware constraints, so efficiency directly creates usable capacity and reliability. At Meta's scale, even small efficiency gains can deliver substantial infrastructure savings while protecting product quality as demand grows. We seek an engineering expert to set direction and lead cross-stack performance work spanning high-throughput services, operating systems and kernels, networking and NICs, CPU and memory, and server platforms. The task is to identify high-leverage opportunities, choose the right layer for each solution, and drive safe fleet-wide deployment with measurable impact on latency, throughput, resource efficiency, capacity, reliability, or total cost of ownership. ## Responsibilities - Set technical direction and lead multi-team programs that improve performance, capacity, efficiency, or reliability - Diagnose interactions across services, operating systems, network I/O, NICs, CPU and memory, and server platforms using profiling, tracing, telemetry, counters, and controlled experiments - Prioritize the highest-leverage opportunities and implement at the right layer, contributing hands-on across layers and partnering where specialized ownership is required - Build representative benchmarks and ship changes with monitoring, validation, staged rollout, rollback, and clear ownership Quantify impact and design trade-offs to influence teams outside the engineer's direct ownership Turn regressions and incidents into systemic prevention, reusable methods, and stronger team capability ## Qualifications - Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience - 7+ years of software-development experience, or a PhD with 4+ years of relevant experience - Track record leading ambiguous, multi-team work from problem framing through large-scale production deployment, with measurable results Deep expertise in at least one area, plus significant hands-on experience in another: high-throughput services, operating systems or kernels, networking or NICs, CPU and memory, or server platforms Experience repeatedly diagnosing and improving systems across two or more of those layers - Proficiency in C or C++, a scripting language, and production performance tools such as profiling, tracing, telemetry, resource attribution, or hardware counters - Ability to communicate impact and trade-offs and influence teams outside direct ownership Ideal candidates combine several of these; mastery of all is not expected Linux internals, kernel networking, drivers, scheduling, packet processing, programmable networking, or NIC offloads Production-representative benchmarking, server or NIC evaluation, large-scale rollout, systems project contributions, or systemic prevention of incidents CPU, cache, memory locality, NUMA, PCIe, power, thermal, or server platform performance C++ systems optimization involving asynchronous I/O, concurrency, memory allocation, caching, transport, or overload handling High-throughput services such as CDNs, proxies, load balancers, caches, gateways, or request-processing systems ## At a glance - Posted by the employer: Nov 4, 2026 - First seen by OpenNash: Nov 8, 2026 - Last checked: Nov 8, 2026 - Listed for: 4 days - Location: Menlo Park, California, US - Employment type: Full-time[Apply on Meta Platforms’s careers site →](https://www.metacareers.com/jobs/1477630144221735/) ## Hiring at Meta Platforms - Open jobs: 1,340 - New in the last 7 days: After two weekly collections - Tracked since: Jul 11, 2026 [All Meta Platforms jobs](https://jobs.opennash.com/companies/meta-platforms/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Meta Platforms ### [Software Engineer - Backend, Standalone Apps Team](https://jobs.opennash.com/companies/meta-platforms/jobs/ddd99212370e3ef2b653/) Menlo Park, California, US ### [Software Engineer - Network Switching](https://jobs.opennash.com/companies/meta-platforms/jobs/3636f0d5fe57b12eb517/) Menlo Park, California, US ### [Software Engineer - Traffic Capacity & Performance](https://jobs.opennash.com/companies/meta-platforms/jobs/c5461bcd5b494a82f6bc/) Menlo Park, California, US ### [Software Engineer, Machine Learning (Technical Leadership) - Ads Products](https://jobs.opennash.com/companies/meta-platforms/jobs/e7f44b733efc71a22946/) Menlo Park, California, US ### [Software Engineer, Product - Ads Products](https://jobs.opennash.com/companies/meta-platforms/jobs/8fb1b331ccbf086a95ee/) Menlo Park, California, US ## Similar jobs at other companies ### [TEMPO- AI Enablement Director - Productivity & Efficiency Leader](https://jobs.opennash.com/companies/truist/jobs/0842ce94366d666ea6c2/) Truist · Charlotte, North Carolina, USA ### [Software Development Engineer II, Efficiency & Performance, Alloy, Region Flex Efficiency](https://jobs.opennash.com/companies/amazon/jobs/6ef8b1eb46fe106cd1cf/) Amazon · US, CA, Sunnyvale ### [Software Development Engineer III, Efficiency & Performance, Alloy, Region Flex Efficiency](https://jobs.opennash.com/companies/amazon/jobs/09e17d2b0dca5609c3d8/) Amazon · US, CA, Sunnyvale ### [Analyst, Energy & Asset Efficiency](https://jobs.opennash.com/companies/carnival-corporation/jobs/f228ecd91d16975959fe/) Carnival Corporation · Miami, FL In Office - Miami ### [Energy Efficiency Engineer](https://jobs.opennash.com/companies/digital-realty-trust/jobs/e488153af93e983dcad8/) Digital Realty Trust · TX, United States [Jobs in Menlo Park, CA](/locations/us/ca/menlo-park/)[Jobs in California](/locations/us-ca/)[Software Engineering jobs](/functions/software-engineering/) OpenNash lists jobs from employers’ own careers sites and does not handle applications.
