Staff Bluetooth Software Engineer

General Motors • Mountain View, CA

34d • Remote

About The Position

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 Bluetooth experts who agree. Our vehicle communication team is hiring a software engineer to design and develop Bluetooth 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 system software fundamentals across the whole stack - from drivers through applications.
• You’ve shipped software at the junction of the Bluetooth stack and the operating system/user features, such as configuration management, device management, audio, or custom Bluetooth application protocols
• You are familiar with userspace services that configure and operate Bluetooth, such as BlueZ, BlueDroid, Fluoride, or vendor-provided stacks
• You know how to triage and debug end-to-end issues in a team, and can perform and analyze packet and HCI captures.
• You enjoy debugging difficult latency and connection issues.
• You understand the upper-level protocols and mechanics of Bluetooth & BLE: device discovery and connections, GATT, audio, etc.
• 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 Bluetooth work perfectly, no matter how old or allegedly flaky a customer’s phone is. You want to make customers happy, and won’t let “other people’s bugs” stand in your way.

Nice To Haves

• Experience collaborating with radio and operating system vendors to debug issues
• Experience with Android Bluetooth
• Work with Bluetooth interoperablility across generations of standards and operating systems
• 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 Bluetooth performance, such as WiFi coexistence at the operating system level
• Knowledge of how Bluetooth works on phone OSes (Android and iOS), and the broader Bluetooth accessory ecosystem (we want every phone to work great with our cars!)
• Familiar with “neighbor” systems that affect Bluetooth user experience, such as audio routing and the audio stack
• The ability to collaborate with hardware engineers to debug antenna, power and operating system issues

Benefits

• GM offers a variety of health and wellbeing benefit programs.
• Benefit options include medical, dental, vision, Health Savings Account, Flexible Spending Accounts, retirement savings plan, sickness and accident benefits, life insurance, paid vacation & holidays, tuition assistance programs, employee assistance program, GM vehicle discounts and more.
