Embedded Software Engineer

Location: Lexington, MA Summary- Designs and implements software of embedded devices and systems from requirements to production and commercial deployment for product lines. Designs, develops, codes, tests, and debugs system software. Involved in specifications, design, and development of embedded firmware in engineering projects. Analyzes and enhances efficiency, stability, and scalability of system resources. Integrate and validate new product designs. Supports software QA. Provides postproduction support. Interfaces with hardware design and development. Experience in embedded systems development. Hands-on development and troubleshooting on embedded targets. Solid programming experience in C or C++. Proven experience in embedded systems design with preemptive, multitasking real-time operating systems. Knowledge of reading schematics and data sheets for components. Strong documentation and writing skills. Background/Need: The Group specializes in advanced network and communications systems development, focusing on mobile, DoD networks operating at the tactical edge. These tactical wireless networks differ from commercial wireless networks in lacking infrastructure for stable connectivity. The DoD operational environment presents additional challenges such as electronic warfare. The Group uses technical analysis, modeling, simulation, emulation, prototype development, and flight tests to develop new communication systems and evaluate their performance.
