Cross-Functional Leadership

• Interface with internal business to collaborate on future product portfolio roadmap.

• Work closely with chipset vendors, contract manufacturers, and internal engineering teams.

• Provide technical guidance to partners and internal teams on hardware integration best practices.

• Mentor junior hardware engineers and contribute to technical roadmaps for future device platforms.

• 8 - 10+ years of HW and Mixed Signal design competence leveraging 5G chipsets into user equipment (UE) products.
• Bachelor of Science in Electrical Engineering, Physics, or other related engineering discipline.
• Demonstrated experience taking designs from paper to product including defining requirements, analytical/simulation design, schematic & BOM creation, design validation and into Production.
• Understanding of Communications Theory and Wireless Communication and how they apply to the design of the UE.
• Previous background developing support documentation such as design guidelines, test plans, test procedures, design and integration guides, ect.
• Proficiency with design process including Specification Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Implementation Complete Review (ICR) and Production Readiness Review (PRR).
• Exposure supporting Contract Manufacturers (CM), OEM's and/or ODM's.
• Understanding of regulatory requirements that impact the UE design and production.
• Problem-solving skills to isolate and resolve complex UE issues when operating within the network.
• Ability to provide technical support across multiple and simultaneous product developments and sustaining activities.
• Aptitude to provide contingency work arounds to preserve schedules.
• Previous experience providing cost and schedule estimates for both new proposals and sustaining activities.
• Sound communication and organizational skills.
• Demonstrated design discipline and rigor.
• Availability to support up to 20% travel (averaged over time).

What will help you on the job

• Master of Science in Engineering is preferred.
• Strong mechanical aptitude.
• Experience working with supply chain to provide technical input on supplier decisions such as make vs buy trade, etc.
