Job Description

We are seeking a highly skilled Python Backend Developer with 6+ years of experience in software development, specializing in software-defined radios (SDR) and radio frequency (RF) communication. This is a strictly backend development role, requiring deep expertise in Python programming, signal processing, and Agile software development methodologies. The ideal candidate will have experience working in multi-Python environments, including Pyenv and Poetry configuration, and a strong background in Ubuntu-based Linux development. This role focuses on building and optimizing backend systems for RF communication applications, emphasizing GPU acceleration, real-time signal processing, and seamless module integration into current and future software pipelines.

Key Responsibilities

• Design, develop, and maintain Python-based backend solutions for SDR and RF communication applications.
• Implement and optimize signal processing algorithms, waveform generation, and RF data analysis using Python.
• Work with SDR frameworks, with a primary focus on SoapySDR, followed by GNU Radio, Ettus USRP, and other SDR platforms.
• Develop Python-based APIs, libraries, and automation tools to streamline RF communication workflows.
• Integrate new software modules into existing and future software pipelines, ensuring compatibility, performance, and scalability.
• Utilize Python libraries such as NumPy, SciPy, Matplotlib, Pandas, PyQt, and scikit-signal for backend data processing and visualization.
• Configure and manage multi-Python environments using Pyenv and Poetry for dependency management and virtual environments.
• Leverage GPU acceleration (CUDA, OpenCL, or CuPy) to optimize real-time signal processing and computation-intensive tasks.
• Perform real-time data analysis, filtering, and transformation of RF signals.
• Develop robust unit tests, integration tests, and performance optimizations to ensure backend software reliability
• Follow Agile development methodologies, participating in daily standups, sprints, and code reviews.
• Work extensively in Ubuntu-based development environments, ensuring software compatibility, stability, and optimization on Linux systems.
• Maintain documentation, version control (Git), and CI/CD pipelines for efficient software deployment.
