## Description

As a Senior Software Engineer you will design, develop, and implement real-time software for RF sensor systems compliant with open architecture standards. You will work as part of focused teams to transition advanced signal processing algorithms from research prototypes into production-quality software for embedded and distributed computing platforms.

What you will do:

 * You will be responsible for architecting software components, implementing real-time processing pipelines, and optimizing performance for resource-constrained RF signal processing systems
 * Translate algorithm specifications (MATLAB, Python) into optimized C/C++ implementations
 * Architect software components compliant with open architecture standards
 * Integrate and optimize code for real-time performance on multi-core CPUs and GPUs with strict latency requirements
 * Develop unit tests, integration tests, and performance benchmarks; promote testing best practices
 * Document software designs, APIs, implementation details, and technical reports
 * Contribute to briefings and presentations for program reviews and customer meetings
 * Collaborate with algorithm developers, systems engineers, RF hardware engineers, and integration teams across programs
 * Contribute to proposal development efforts including technical approach
 * Perform peer reviews and suggest next steps for technical work
 * Support approximately 20% travel for integration events, customer meetings, and field demonstrations
