Software Engineer - Rust/C++ High Performance DSP

Software Engineer • Rust/C++ High-Performance DSP We are looking for a Software Engineer with strong Rust and C++ skills to build a high-performance Linux desktop application for real-time radio signal analysis and visualization . The system combines DSP → post-processing → UI → GPU rendering , processing large volumes of data with strict throughput and latency requirements. Responsibilities Develop high-performance, multithreaded DSP and data-processing pipelines in Rust . Build custom 2D/3D visualization using egui/eframe, wgpu , and WGSL. Develop and maintain GNU Radio C++17 blocks and flowgraphs . Design high-throughput shared-memory IPC and ring buffers . Manage GNU Radio child processes from Rust, including lifecycle and cancellation. Prototype and validate DSP algorithms using Python, NumPy, Matplotlib, and Jupyter . Profile and optimize CPU, memory, synchronization, and GPU performance. Requirements Strong Rust experience: ownership, lifetimes, multithreading, atomics, synchronization, FFI, and subprocess management. Strong C++17 and CMake experience. Familiarity with GNU Radio block APIs and scheduling. Experience with ring buffers, shared memory, streaming, and zero-copy architectures . Experience with SIMD/vectorization and performance optimization. Experience with egui/wgpu or GPU programming ; WGSL is a plus. Strong Python/NumPy skills for numerical prototyping and validation. Linux development experience. Performance-oriented mindset and strong debugging skills. Nice to Have DSP / SDR experience FFTs, filtering, detection, IQ processing Lock-free or SPSC/MPSC architectures rayon / crossbeam perf , flamegraphs, RenderDoc Qt / Qt Widgets or Qt Quick USRP or other SDR hardware Rust/C++ hybrid Cargo + CMake projects
