* The Opportunity:

*** Design, architect, and implement complex embedded RF systems as part of a multi-disciplinary team working on specialized tools, sensors, and communications devices for demanding applications
* Contribute to software architecture decisions for inter-processor and microservice systems where your technical choices directly impact system performance, real-time behavior, and the ability to process high-rate RF data in resource-constrained environments
* Work with engineers across the full embedded system stack—from signal processing algorithms to FPGA fabric, from application layer to hardware interfaces
* Own technical design from initial architecture through production deployment, making practical trade-offs between competing constraints like schedule, performance, portability, and maintainability
** Responsibilities:
*** Design distributed software architectures spanning multiple processing domains (x86, ARM, FPGA fabric), defining communication patterns and data flows for real-time RF signal processing systems
* Develop high-performance C++ frameworks for inter-processor communication in systems where latency and throughput are critical constraints
* Create technical documentation including message sequence charts, UML class diagrams, and software architecture specifications that enable distributed teams to build complex systems correctly and efficiently
* Design microservice architectures for x86 and ARM platforms, balancing modularity, performance, and resource constraints
* Profile and optimize software for memory-bound and compute-bound workloads using tools like vTune, identifying bottlenecks and implementing measurable performance improvements
* Work with signal processing engineers to design data pipelines that move RF samples from ADCs through filters, demodulators, and decoders
* Develop debugging approaches for resource-constrained embedded systems where standard tools provide limited visibility
* Build C++/Python test harnesses and unit tests that generate representative workloads, validate system behavior, and verify edge cases
* Integrate modern development tools and practices including CI/CD pipelines, containerization, and build automation
* Collaborate with FPGA engineers to define hardware/software interfaces that leverage programmable logic capabilities while maintaining software flexibility
*
* Qualifications:

*
*
* Required:

** 5-7+ years of professional software engineering experience in embedded systems and/or high-performance computing in Linux based environments
* BS or MS in Computer Science, Software Engineering, Electrical or Computer Engineering, or related field
* Strong proficiency in C++ development for embedded real-time systems, including concurrency, memory management, and optimization techniques
* Demonstrated experience designing and implementing software architectures and communicating technical concepts through documentation and diagrams
* Experience with multi-threaded application development and debugging concurrency issues, including race conditions in inter-processor and microservice architectures
* Working knowledge of software design patterns and development methodologies for complex systems
* Experience with modern build systems and Dev Ops tools (Conan, Docker, Git Lab or similar)
* Experience with performance analysis and debugging tools (vTune, perf, gdb, valgrind, or similar) to identify and optimize bottlenecks
* Ability to make informed trade-offs between portability, performance, and architecture-specific optimizations
* Desired:
** Experience with communications systems and digital signal processing, including filters, modulation/demodulation schemes, channel equalization, and forward error correction (FEC)
* Experience with wireless communications protocols (3
