    • Support the RF certification and compliance testing of radio/system reference platform designs through both in-house screening and formal testing at a 3rd-party certified test lab
    • Continuously work to improve the development process, concentrating on time to market, quality, and cost Specific Knowledge/Skills
    • Establishes requirements for highly complex RF design projects and may lead a team responsible for establishing requirements. Insure correct features are incorporated first in the projects. Insures correct features are incorporated first in the projects.
    • Architects and designs highly complex RF design projects. Completes all phases of the projects. Follows through on all in-process and final inspection activities.
    • Creates new programs, technologies and solutions based on novel or unique ideas. Insures new ideas and methodologies are documented for use by the team.
    • Uses status as a knowledge leader in RF design and functional knowledge across multiple engineering disciplines and program management to provide technical leadership to a given program.
    • Defines requirements for and may design complex new tools to aid in the analysis and solving of complex problems.
    • Initiates cross-company collaboration and develops positive relationships with other engineering disciplines.
    • Exercises judgment (within broadly defined policies and practices) in selecting methods, techniques and evaluation criteria for obtaining results.
    • Networks with key contacts outside own area of expertise. Interacts with management and senior customer personnel on matters requiring coordination across organizational lines. Represent the organization as the principal customer contact and often performs project leadership
