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. \n\nThis 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.\n\nLead and participate in the design, and development of our next generation Products.\n\nWork closely with a team of software engineers to translate overall system architecture and product requirements into well-designed and implemented software components.\n\nParticipate and conduct technical reviews of system design and interface requirements and provide technical feedback and make recommendations.\n\nServe as the primary engineering escalation point for complex customer issues on Linux-based CollabOS devices, performing deep technical triage and root cause analysis.\n\nDevelop fixes, workarounds, and patches for identified issues, coordinating with platform teams to ensure proper integration into mainline releases.\n\nCreate diagnostic tools, scripts, and documentation that improve the efficiency of future troubleshooting efforts.\n\nDrive proof-of-concept development and feature work as capacity allows, contributing to platform improvements informed by real-world customer feedback.\n\nAnalyze device telemetry and logs to identify patterns, predict issues, and propose systemic improvements.\n\nBuild and maintain knowledge bases and escalation procedures that capture tribal knowledge and enable faster resolution times.\n\nWymagania\nMUST \nYou have 5+ years of hands-on experience with Linux based embedded platforms.\n\nYou have deep knowledge of Linux platform internals: kernel, systemd, device drivers, and IPC mechanisms (D-Bus, gRPC, ZeroMQ, Unix sockets).\n\nYou possess strong proficiency in C, C++ (C++17), Python, and shell scripting, with the ability to read and debug code across system layers.\n\nYou have broad knowledge across the Linux system stack, including kernel internals, device drivers, networking subsystems, and userspace frameworks.\n\nYou are experienced with debugging tools and techniques: strace, ltrace, gdb, perf, ftrace, tcpdump/Wireshark, journalctl, and similar utilities.\n\nYou have a basic understanding of the TLS protocol and networking layers.\n\nYou communicate effectively with both technical and non-technical stakeholders, translating complex issues into clear explanations and actionable recommendations.\n\nYou are comfortable working directly with enterprise customers and partner engineering teams when needed.\n\nNICE TO HAVE \nLinux platform build systems (Yocto, Buildroot) and Git workflows\n\nYou have working knowledge of networking protocols and enterprise networking concepts (802.1x, RADIUS, certificates, proxies, VLANs) and are familiar with Network troubleshooting and protocol analysis (Wireshark, tcpdump, 802.1x)\n\nYou understand video conferencing technologies: codecs, WebRTC, SRTP, SIP, or similar protocols.\n\nYou have a good understanding of DRM/KMS display subsystems and V4L2 camera frameworks\n\nUSB stack
