As a senior engineer in our product operations team in our Custom SoC business unit, you will have latitude to be an innovative engineer who is encouraged to forge ahead toward doing things the right way, instead of status quo.  You will be involved in the decision-making process in selecting the correct package type upfront, and be able to provide your input as the die layout is being defined, instead of reacting to whatever is thrown over the design wall.  You will manage the package design and development of your own projects with our subcontractors, build prototypes, and coordinate the qualification.  You will be responsible for planning the ramp-up to production and all sustaining activities for high volume production. This is a unique opportunity to make a significant impact in our industry.
