Job Title: Software Developer
Duration: 3+ Years
Location: Lexington, MA
Description:
Develops application software by writing and implementing efficient code. Researches, designs, develops, and implements software applications and systems. Involved in planning system deployment and responsible for meeting software compliance standards. Evaluates, designs, and implements interfaces between hardware and software, operational requirements, cloud offerings, system architecture, security, and characteristics of overall systems. Researches, designs, implements, and manages software programs. Identifies areas for modification in existing programs and develops these modifications. Determines operational practicality. Documents testing, client experience, and maintenance of system corrections. May collaborate with cybersecurity teams to ensure compliance with security standards and may develop and conduct unit tests.
Background/Need:
The Group requires a software developer with experience in developing both digital signal processing code and user applications for RF communications. Develops software for RF communications applications, including signal processing blocks, networking, GUIs, and operator-facing applications. Writes code for software defined radios (SDRs) such as Ettus USRPs (X310s and/or X410s) that act as RF interfaces. Develops optimized signal processing code for GPUs (C/CUDA) and for SDR Xilinx FPGAs (Verilog, VHDL, RFNoC). Creates unit and end-to-end tests to verify software and system functionality. Debugs issues (MATLAB experience helpful). Verifies software meets timing requirements for real-time functionality and creates polished GUIs or applications based on operator feedback. Code development spans real-time applications on GPUs and SDRs as well as non-real-time applications.
Job Responsibilities:
- Configure programming environments and tools (Python, UHD, containers) for collaborative coding and software transfers
- Design and set up digital signal processing blocks on GPUs based on models and MATLAB code
- Develop production-ready software for deployment and transfers
- Develop local and web-based GUIs for operators
- Report internally via verbal and written methods
