Implement new software components, frameworks, and applications. Collaborate with cross-functional teams to define, design, and ship new features.

Minimum Qualifications 8+ years industry experience. Deep technical understanding and hands-on experience with software development and lifecycle management. Experience with low-level OS systems, i.e. kernel, Darwin or drivers. Deep experience with power and performance measurement and investigation techniques. Solid computer science fundamentals. Excellent communication and interpersonal skills for collaborating with a technical team.

Preferred Qualifications Experience defining and contributing to application or systems architecture. Ability to work with technology partners at all levels of the stack, from hardware, sensors, and firmware to frameworks and applications.
