Senior Software Engineer
As a Senior Performance & Tooling Engineer at PlayStation Global, you will be instrumental in designing and building advanced performance testing and monitoring tools. Your work will enable development teams to measure, optimize, and scale system performance across Linux, CPU, DPU, and PCIe environments. This role offers the opportunity to work on deeply technical, low-level engineering challenges that have a direct impact on product performance and reliability.
In this position, you will design, build, and own a performance tooling suite across CPU/DPU/PCIe. You will develop load generators to saturate PCIe, NICs, and storage paths, modeling real-world and worst-case network/storage traffic. Additionally, you will instrument the stack with Linux perf, ftrace, and eBPF to capture timings, contention, cache/memory effects, and I/O paths. Creating repeatable experiments to characterize throughput, latency, jitter, tail behaviors, and scalability limits will also be a key part of your responsibilities.
The ideal candidate will have a BS in Computer Science or Software Engineering, or 5+ years of experience building low-level performance and load-testing tools. Proficiency in one or more systems languages (C/C++/Rust) and scripting for automation (Python/Bash) is required. Mastery of Linux performance monitoring and tracing tools (perf, ftrace, eBPF/bcc/libbpf) in production environments is essential. A deep understanding of the x86-64 microarchitecture and strong knowledge of PCIe, including link training, lanes, bandwidth math, peer-to-peer, DMA, and device/driver interactions, is also necessary.
At Sony Interactive Entertainment, we consider several factors when setting each role’s base pay range, including competitive benchmarking data for the market and geographic location.
