GLOBAL TECHNOLOGIES

5+ years of experience with Linux device driver development, preferably with a focus on PCIe devices.Open Source Contribution: Experience contributing to the Linux kernel or relevant open-source projects is highly valued.Expertise in C Language: Mastery of C for low-level, performance-sensitive code, including bitwise operations, memory management, pointer arithmetic, and data structure optimization.Familiarity with C++: Advantageous for certain projects, though most Linux kernel drivers are written in C. Understanding object-oriented concepts in a C context is also helpful.Deep Understanding of Linux Kernel Architecture: Familiarity with kernel space versus user space, kernel modules, device driver concepts, and memory management.Kernel Module Development: Experience writing loadable kernel modules (LKMs) and integrating them with the Linux build system.Debugging and Profiling: Proficiency with debugging tools such as kgdb, ftrace, perf, dmesg, and sysfs interfaces to troubleshoot and optimize drivers.Comprehensive Understanding of PCIe Specification: Knowledge of the PCIe standard, including enumeration, configuration space, BARs (Base Address Registers), MSI/MSI-X interrupts, and bus mastering.Device Datasheet Interpretation: Ability to read and interpret PCIe device hardware documentation, including register maps, timing requirements, and signaling protocols.Interfacing with Firmware/BIOS: Understanding how PCIe devices are initialized during system boot, and the mechanisms by which firmware and BIOS communicate with hardware.Device Driver Development LifecycleProbing and Initialization: Experience writing probe() and remove() functions to handle device enumeration and teardown.Resource Management: Skills in managing memory and hardware resources, including DMA (Direct Memory Access), I/O regions, and interrupt lines.Interrupt Handling: Ability to write efficient and robust interrupt handlers, using mechanisms such as bottom halves, tasklets, work queues, and threaded interrupts.Power Management: Familiarity with runtime and system power management interfaces, including suspend/resume operations.Concurrency and Synchronization: Understanding race conditions, atomic operations, spinlocks, mutexes, and semaphores in a preemptible kernel environment.Bachelor&rsquo;s or Master&rsquo;s Degree: In Computer Science, Electrical or Computer Engineering, or a related technical field.Desirable Additional Qualifications:Knowledge of Other Operating Systems: Familiarity with Windows, FreeBSD or RTOS driver models for cross-platform development.Experience with FPGA, SoC, or Custom Hardware: Useful for teams working on nonstandard PCIe endpoints or accelerators.Performance Tuning: Skills in profiling and optimizing for low-latency, high-throughput data paths.Community Engagement: Involvement in Linux kernel mailing lists, conferences (such as Linux Plumbers Conference), or speaking at industry events.Note: Please send Cv only, who can attend the interview weekdays, with short notice period (max 15 days only)Job Location: Bangalore (Work from office)Job Type: Full-timePay: &#8377;1,691,666.37 - &#8377;4,003,384.60 per yearBenefits:<ul><li>Provident Fund</li></ul>Work Location: In person
