You will work at the intersection of SoC architecture, cellular systems, firmware, operating systems, and radio-access-network workloads, helping deliver industry-leading performance and energy efficiency. This role focuses on software for 5G and emerging 6G infrastructure, including Radio Units (RUs), Distributed Units (DUs), and the interfaces connecting them. You will collaborate with hardware, architecture, platform, networking, and cellular-software teams throughout pre-silicon development, silicon bring-up, productization, and deployment. What you'll be doing: * Design, develop, test, and optimize system software and firmware for SoCs used in O-RAN and cellular infrastructure. * Develop power-management policies and performance optimizations across CPU, GPU, accelerator, memory, interconnect, I/O, and networking subsystems. * Analyze representative RU and DU workloads to identify architectural and system-level bottlenecks, including compute, memory bandwidth, latency, synchronization, and data-movement constraints. * Develop and tune power-management capabilities such as dynamic voltage and frequency scaling, clock and power gating, idle-state management, thermal controls, and system-level power budgeting. * Create performance and power models, measurement tools, benchmarks, and automated test infrastructure for both pre-silicon and post-silicon environments. * Use simulation, emulation, prototyping, and production silicon to validate architectural decisions and identify power and performance issues. * Evaluate system behavior against O-RAN and cellular-interface requirements, including timing, synchronization, latency, throughput, and reliability. * Influence future SoC, platform, and cellular-software architectures based on workload analysis and measurements from deployed systems. ## Related Videos - [HTTP headers that make your website go faster](https://www.wearedevelopers.com/videos/1676-http-headers-that-make-your-website-go-faster) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Coffee with Developers - Stephen Jones - NVIDIA](https://www.wearedevelopers.com/videos/1303-coffee-with-developers-stephen-jones-nvidia) - [Event based cache invalidation in GraphQL](https://www.wearedevelopers.com/videos/433-event-based-cache-invalidation-in-graphql) - [Accelerating Python on GPUs](https://www.wearedevelopers.com/videos/859-accelerating-python-on-gpus) - [Agent Smith Gets Hardware: Autonomous IoT Hacking From Debug Port to Cloud API](https://www.wearedevelopers.com/videos/100258-agent-smith-gets-hardware-autonomous-iot-hacking-from-debug-port-to-cloud-api) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Top 6 Hackathons for Developers in 2023](https://www.wearedevelopers.com/magazine/263-top-6-hackathons-for-developers-in-2023) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [What Jobs Can You Get with a Software Engineering Degree?](https://www.wearedevelopers.com/magazine/398-what-jobs-can-you-get-with-a-software-engineering-degree)
