Senior Radio Firmware Engineer

Job description

Develop, test, and maintain the low-level firmware drivers that abstract a consistent, future-proof, and well-documented interface to the radio of Renesas wireless SoCs, throughout the complete IC development cycle. Closely follow standardization efforts and translate existing and roadmap radio PHY requirements into highly efficient firmware solutions, in order to provide Renesas a competitive advantage in the IC market.

Contribute to shaping the future of Renesas wireless products.

Principal Accountabilities

Implement, test, and maintain the radio low-level firmware drivers for wireless SoCs. Fine-tune the firmware for optimal performance, energy efficiency, resource utilization, and reliability. Contribute to the integration of the radio low-level drivers into wireless protocol stacks. Develop and maintain radio low-level firmware for IC simulation, production test, lab evaluation, qualification, and characterization. Implement and maintain automated regression tests for the radio firmware.

Troubleshoot firmware / software and architectural issues. Create and maintain documentation and Application Notes. Schedule own tasks, report progress to project leader, identify possible project issues. Work closely across teams and contribute to datasheets, architectural spec’s and development plans for new designs.

Qualifications

Industry experience in Embedded Software for ARM or DSP cores. Background in highly resource-constrained, real time, embedded environments. Solid C and Python Language skills. Experience with Assembly Language for at least one microcontroller family. Experience with software engineering processes and the full software development lifecycle, including requirements, design, implementation, testing, and deployment. Experience with version control systems, e.g.

Git. Proficiency with electronics bench test equipment, e.g. logic analysers, debug probes, oscilloscopes, spectrum analysers. Proficiency in problem solving and debugging skills. Eagerness to contribute new ideas, build consensus, and drive tasks to completion. Desire and mental agility to quickly understand new ideas in novel domains. Excellent team working skills, multi-disciplinary focus. Talent for clearly communicating challenging technical subject matter.

Fluent in English language (written and oral). Desirable Knowledge / experience in any of the following fields is an advantage: low-level drivers, low power wireless protocol stacks (Bluetooth, Thread, Zigbee etc.), MAC and Physical Layer (PHY) techniques, Software Defined Radio techniques, Digital Communication Theory, DSP Theory, MATLAB. Familiarity with embedded software tools such as GCC, GDB, Make, CMake etc. Experience with chip development flow / commercialization.

Understanding of hardware vs. software trade-offs, and experience in specifying hardware requirements and working with hardware engineers. Familiarity with hardware description languages. Experience in Test Methodologies / Automation; familiarity with Wireless Communications test equipment. Strong mathematical fundamentals. Published scientific/technical articles or presented papers at technical conferences.
