Contract - 03 Years

Location (mandatory): Lexington, MA We are seeking a talented embedded DSP software engineer to develop, optimize, and maintain signal processing solutions for a tactical communications program within the Group. The group leverages technical analysis, modeling, simulation, emulation, prototype development, and flight tests to advance communication systems and evaluate their performance. This role focuses on developing high-performance DSP algorithms and embedded software for specialized processor architectures. The ideal candidate will have strong fundamentals in digital signal processing, experience with commercial DSP platforms, and the ability to work across hardware-software boundaries to deliver optimized solutions for real-time communications systems.

Job Responsibilities:

  • Develop and optimize DSP algorithms for tactical communication systems on commercial DSP platforms (NXP, TI, CEVA, or similar)
  • Develop software for RTOS environments with focus on task scheduling, inter-task communication, and interrupt handling
  • Write and debug low-level assembly code to maximize performance on DSP architectures
  • Collaborate with hardware engineers on board bring-up and system integration activities
  • Support CI/CD pipelines and maintain version control using Git
  • Leverage AI development tools (Copilot, Cursor, Claude Code, etc.) to accelerate development workflows
  • Debug complex issues spanning DSP firmware, RTOS, and hardware interfaces
  • Document designs, algorithms, and code to support long-term maintainability

Skills:

  • Experience developing code for commercial DSP chips/IP (NXP, TI, CEVA, or similar architectures)
  • Proficiency in C/C++, Python, and MATLAB for signal processing and embedded development
  • Understanding/Experience with Bare-Metal programing (i.e. direct register-level programming of peripherals, clock and power domain initialization, cache and MMU setup)
  • Experience with RTOS environments(i.e. task/thread scheduling, inter-task communication mechanisms, and interrupt handling)
  • Experience with assembly language programming (NXP-VSPA ISA knowledge preferred, but proficiency in x86/x64, ARM, etc. is acceptable)
  • Strong DSP fundamentals (i.e. frequency domain vs. time domain analysis, FFT/IFFT implementation, and FIR/IIR filter design)
  • Experience with AI-powered development tools and workflows (Copilot, Cursor, Claude Code, etc.)
  • Proficiency with Git version control
  • High ownership mentality: takes responsibility for outcomes and system reliability
  • Ability to work effectively in fast-paced, loosely defined environments
  • Strong problem-solving skills and ability to work both independently and collaboratively
  • Knowledge of wireless communication system protocols and standards

Education/Experience:

  • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related discipline
  • 3+ years of experience in embedded software development with focus on DSP application
  • Experience with CodeWarrior IDE and NXP development toolchains
  • Experience with board bring up and boot process (i.e. First-stage bootloader, U-boot, Device Tree, etc.)
  • Experience with JTAG debugging and hardware-software integration
  • Understanding/Experience in Embedded Linux development (i.e. kernel configuration, patching, building, device tree authoring/debugging, kernel module dev, root file system creation, etc.)
  • Previous work on tactical or software-defined radio (SDR) systems
