Overview:

Airbnb is looking for an experienced lead embedded Linux kernel engineer based in San Francisco. This is  a senior leadership role with the responsibility to shape the engineering design of the consumer electronics product line.  This is an opportunity to get on the ground floor of a new organization, and help establish the technical direction of the team,  and help shape the engineering culture and its standards of excellence. This individual will have hands-on involvement and oversight of all aspects of hardware development, including working collaboratively within a highly technical cross-functional team.  You will play a key role in meeting key requirements for overall engineering, manufacturability, time to market, and cost. The role comes with ample opportunity to engage with leadership at all levels of the organization.

You will work collaboratively with teams from Industrial Design, User Experience, Software, Supply Chain, Operations Program Management, and Manufacturing, in addition to the multiple disciplines within Hardware Engineering. You will translate high-level requests and communication into actionable hardware direction, working with key stakeholders to ensure agreement on the proposed solution and generating the necessary documentation to facilitate implementation.

We are seeking a lead with strong engineering and communications skills who can provide guidance and empower the technical teams and influence major engineering decisions. This is a cross-functional role and we are looking for a team player who loves collaboration and never shies away from a problem.

  • Partner with hardware for device bring-up
  • Write peripheral drivers, bootloaders, DMA pipelines, core management layers (power manager, connectivity manager, etc).
  • Create and execute hardware bring-up plans and test plans
  • Create and document hardware architecture, bring-up plans, test plans
  • Implement secure communication between consumer electronics products and between embedded hardware and cloud server backends
  • Create and implement a robust architecture for over-the-air updates 
  • Experience in writing BSP and Device Drivers (MIPI, PCI, SDIO, PMIC, I2C, I2S, Audio, Display LCD/MIPI etc.)
  • Track test progress, bugs, and fixes and drive changes to design based on resolution
  • Work closely with CM resources to leverage their engineers and maximize the focus of internal resources on adding value to our products
  • Coordinate and communicate with external contract manufacturing partners in different global locales, and work around language and culture barriers to establish good working relationships.
  • Travel in the Contiguous US and globally as needed to support product launches.

Minimum Qualifications:
