Senior Software Engineer (Linux)

Description

This role is for an experienced Linux Platform Engineer who thrives on solving complex, ambiguous technical problems across the full system stack. You will be the engineering point of contact for critical customer escalations on our next-generation Linux-based devices, including cameras, microphone pods, switches, and other peripherals. Beyond reactive support, you will drive proactive improvements, develop proof-of-concept solutions, and contribute to feature development that prevents future issues. This is not recipe-based technical support. You will operate as a full-stack systems engineer, hunting down root causes in kernel logs, network traces, audio pipelines, and video subsystems. You will propose and implement fixes, collaborate with product engineering teams, and ensure our enterprise customers have world-class experiences. You will be responsible for overall system design and development efforts. You will be responsible for optimizing core aspects of the software that are critical to product design and experience.
