Requirements
- BS with 3 plus years of industry experience.
Responsibilities
- Deep understanding of components/modules within wireless communication systems and the corresponding calibration and impairment reduction techniques
- Develop methods/algorithms to alleviate hardware induced impairments by calibration, cancellation and other applicable techniques
- PHY firmware architecture and design, including calibrations, real-time processing flows, collaboration with RF hardware, microcode, and MAC layer.
- Develop highly efficient designs delivering outstanding performance, optimizing power and memory footprints while meeting hard-realtime latency requirements.
- Debug real-time systems with limited visibility, working hands-on with development boards and lab equipment.
- Collaborate with Radio, MAC, and Systems engineering teams to architect, define and implement innovative algorithms, calibrations, and protocols.
- Support pre-silicon validation efforts, including simulation, emulation, and FPGA prototyping.
- Develop SoC test and calibration capabilities for chip, module, and product factories.
- Support post-silicon bringup, validation, performance characterization, system integration and debugging.
- Repeatedly measure and optimize results using various test harnesses
- Automate calibration and verification processes.
Preferred Qualifications
- Hands-on experience and working knowledge of wireless systems and protocols such as LTE/NR/WiFi/Bluetooth
- Excellent problem-solving skills to address technical issues during design, development and maintenance phases
- Strong embedded SW fundamentals, including knowledge of design and development-flows, real-time constraints, concurrency, multi-processor systems, caching and virtual memory.
- Deep understanding of data structures, object-oriented design, and system architecture in an embedded environment
- Strong software engineering skills including design, development (using C, C++), scripting (Python), and debugging
- Familiarity with low-level hardware interfaces, register and interrupt programming, bare-metal software development, clock and power management.
- Experience with configuration (GIT, Perforce) and release management, continuous integration, unit and regression testing.
- Strong understanding of design strategies for maintainability, scalability, and code reuse.
- Excellent communication skills – both written and oral.
- Highly organized, motivated and passionate about driving results
