About The Position

The Cellular Software Enablement Engineer will join Apple’s Cellular CoreBSP Enablement team within the Cellular Software & Technologies organization. The team brings up firmware on new cellular modems and integrates them into Apple products with cellular connectivity, supporting the process from first boot through production readiness and commercialization. The position is based in Santa Clara Valley.

The engineer will own cellular modem product bring-up in new Apple devices, from early builds through production readiness, and support new modem bring-up from pre-silicon emulation through post-silicon hardware. The role includes hands-on debugging across the hardware and software stack, maintaining device labs and development hardware, and developing machine learning models to optimize cellular firmware on the platform. The engineer will work with data providers and use-case teams from problem definition through on-device deployment.
