Your Team, Your Impact

Marvell is a market leader in Connectivity Semiconductor products (PHYs) that are widely deployed in every major cloud data center and AI cluster.

You will provide documentation and facilitate knowledge transfer, in order to hand-off further enhancement and maintenance of your design to the implementation team.

In return, as you iterate through such strategic engagements, you will regularly be exposed to novel ideas, working on new features, and integrating into a variety of interesting products. You will accumulate wide-ranging knowledge and play an impactful role in propagating best practices to many design teams.

  • Strong firmware engineering background, with working knowledge in digital design; OR vice-versa.
  • Robust Communications Skills in Listening & Teaching.

Expected Base Pay Range (USD)

177,820 - 266,400, $ per annum
