The role also includes innovation & technical leadership, mentoring and supervision of junior engineers, pre-silicon and post-silicon validations or their supervision, support to application and production test engineers, and definition of test methodology. Responsibilities: Define, develop, verify and optimize embedded firmware for low-power mixed-signal circuits. Design embedded firmware functions, sub and full systems, from specification definition to support to production. Develop and deploy rule-based and ML-based inference firmware, leveraging AI-assisted development tools and workflows. Implement testability and diagnosis features to support hardware testing. Generate technical documentation and drive design reviews. Define and implement pre-silicon simulation validation, unit and regression testing, debug, emulation, and FPGA prototyping. Support top verification. Specify and implement system-level and hardware-firmware architectures, from top-level specification analysis to system and firmware optimization. Evaluate and specify CPU/micro-controller selection and ROM/RAM memory sizing based on system requirements and constraints. Support silicon lab evaluation, performance characterization and debug. Provide comprehensive post-silicon customer technical support, RMA analysis and field issue resolution. Interface with system, digital hardware, analog, verification and cross functional teams. Mentor and supervise junior engineers. Technical support to test, product and application engineers.
