Expected Results System architectures and interface standards that scale across multiple product platforms Complete, prioritized product requirements that enable on-schedule launch of new product lines from concept to mass production Harmonized interfaces across current and future designs that reduce development and validation time Vendor-ready protocol library specifications with clear release testing requirements System-level verification and validation strategies that reduce field issues and release risk Effective cross-functional alignment and development of Systems Engineers through mentoring Essential Duties & Responsibilities System Architecture Leadership Lead the definition of system and software architectures for embedded platforms across multiple product lines. Define the partitioning of functions across MCUs, hardware, firmware, and cloud systems, including the roles and responsibilities of each MCU. Lead system architecture and interface reviews, and make trade-off decisions balancing performance, power, cost, reliability, and schedule. Verify that architectures and interfaces meet timing, throughput, and frame/packet size requirements for all use cases. Interface Standards & Harmonization Establish standardized microprocessor interfaces and interconnects between printed circuit board assemblies. Update existing interfaces to harmonize current and future designs, leveraging reusable design components to speed development. Own protocol library requirements and the release testing requirements for libraries distributed to vendors. Requirements Leadership Lead the translation of commercial requirements into firmware and system product requirements for new product lines from concept to mass production. Define and propose algorithms based on commercial requirements, and resolve requirement conflicts across functions. Establish requirements traceability from commercial needs through design, verification, and release. IoT & Connectivity Architecture Lead the definition of IoT device-to-cloud protocols, data payloads, and client/server interfaces in partnership with Cloud Engineering. Ensure device-to-cloud interfaces are secure, efficient, scalable, and supportable across product generations. Verification & Validation Strategy Define system-level verification and validation strategies, monitoring and test interfaces, and release criteria for firmware features. Lead system-level root cause analysis of complex integration and field issues with Firmware, Hardware, Test Engineering, and Technical Support. Technical Leadership & Continuous Improvement Mentor and develop Systems Engineers, and serve as a technical knowledge resource for Firmware and Hardware Engineering. Facilitate communication to align design teams on standard interfaces, and present concise technical recommendations to engineering leadership. Recommend and implement improvements to systems engineering processes, documentation standards, and tools, and publish and archive technical requirements and analysis.
