Staff WiFi Engineer

The role  

We think wireless communication can be perfectly reliable – no matter what conditions and hardware our customers throw at it.  We’re looking for WiFi experts who agree.   

Our vehicle communication team is hiring a software engineer to design and develop WiFi software in our Linux-based networking system.  Join us to develop the best connectivity experience found in any car. 

What you'll do  

GM is developing a  breakthrough new system  for vehicle software and communications, and you'll be at the heart of it.  We design our own hardware, so you'll work closely with hardware teams to meet the tough power, signal, and reliability requirements of vehicles.   You'll also work closely with our application and cloud teams to ensure end-to-end reliability and performance.  

Requirements:  

• You should know Linux/POSIX systems and networking fundamentals across the whole stack - from drivers through applications.   

• You’ve shipped software at the junction of the WiFi stack and the operating system/user features, such as configuration management, network configuration, power management, or tethering 

• You are familiar with userspace services that configure and operate WiFi, such as wpa_supplicant, cfg80211/nl80211, hostap, NetworkManager, or ConnMan 

• You know how to triage and debug end-to-end issues in a team, and can perform packet capture, characterize latency, and analyze connection and roaming failures 

• Most of our code is written in C, C++, and Java, so we expect you know at least one of these languages well.   

• BS/MS/PhD in computer science or electrical engineering (or equivalent experience) 

• 5+ years software development experience  

• Most importantly, you have a deep drive to make WiFi work perfectly, no matter how old or allegedly flaky a customer’s phone or router is.  You want to make customers happy, and won’t let “other people’s bugs” stand in your way. 

Preferred qualifications:    

• Experience collaborating with radio and operating system vendors to debug issues 

• Experience with Android WiFi and connectivity  

• Work with WiFi interoperablility across protocol generations, security, and roaming standards  

• Ability to build a power-aware system by balancing reliability and power consumption via scanning/roaming policies and suspend/resume behavior.  This should be supported by experience with measuring power consumption 

• Work with lab/field testers, test automation, and certification/interoperability efforts 

• Work with related systems that can affect WiFi performance, such as Bluetooth coexistence at the operating system level 

• Knowledge of layer 1 and layer 2 issues that can affect performance 

• The ability to collaborate with hardware engineers to debug antenna and power issues
