Senior Linux Kernel Engineer

Job description

As a Senior Linux Kernel Engineer at MBRYONICS, you'll be a vital player on our engineering team, architecting, developing, and optimizing the low-level software platform that powers our cutting-edge optical communication systems. This is an excellent opportunity to own the OS layer, dive into high-performance kernel-space development, and lead hardware-software integration in a fast-paced, high-tech setting. What you'll do Kernel & Driver Development: Design, implement, and debug custom Linux kernel drivers and subsystems used in our Free Space Optical Communication hardware. BSP Architecture: Architect, build, and maintain custom Board Support Packages (BSPs) using tools like Yocto Project or Buildroot. Performance Optimization: Optimize the Linux kernel and user-space interfaces for real-time responsiveness, low latency, high throughput, and deterministic behavior. Hardware Bring-up: Lead the initial bring-up of new custom hardware platforms, collaborating closely with electronics engineers to validate silicon and board designs. Lifecycle Leadership: Own the low-level software lifecycle—from architectural requirements and design to upstreaming patches, deployment, and long-term maintenance. Quality & CI/CD: Mentor the team on modern kernel testing methodologies, expanding our CI/CD pipelines to handle hardware-in-the-loop (HIL) testing and automated kernel builds. Technical Governance: Conduct rigorous code reviews, establish low-level coding standards, and maintain thorough documentation for software design and system architecture. Continuous Innovation: Keep up-to-date with upstream Linux kernel developments, security patches, and emerging real-time Linux technologies (e.g., PREEMPT_RT). Who you are Education: A Master's degree or PHD in Computer Engineering, Electronic Engineering, Computer Science, or a related field. Kernel Expertise: Extensive, proven industry experience in Linux kernel development, writing custom character/block device drivers, and navigating the Linux kernel source tree. Embedded Linux Mastery: Deep understanding of the embedded Linux boot sequence (U-Boot/barebox), device trees, memory management, concurrency, and interrupt handling. Tooling Proficiency: Expert knowledge of build systems like Yocto Project, Buildroot, or OpenEmbedded, alongside deep familiarity with Git. Low-Level Protocols: Proven experience writing and debugging software for hardware interfaces such as SPI, I2C, UART, PCIe, CAN bus, and DMA engines. Networking Stack: Strong understanding of Linux network architecture, sockets, and high-speed interfaces (Ethernet, TCP/IP, UDP). Debugging Skills: Exceptional problem-solving skills using advanced debugging tools (GDB, JTAG/ICE probes, oscillo-scopes, logic analyzers) and kernel tracing utilities (ftrace, perf, printk). Soft Skills & Passion: Strong communication and leadership skills with the ability to collaborate effectively across disciplines. A genuine passion for low-level software engineering and space technology. What's in it for you Career Growth: Contribute to a world-class space-age communication program while developing your technical leadership skills in a state-of-the-art manufacturing environment. Collaboration: Work with talented professionals across disciplines to drive impactful solutions. Innovation: Be part of a team pioneering advancements in manufacturing engineering for cutting-edge FSO systems. Work-Life Balance: Enjoy flexible work schedules and a comprehensive benefits package. If you're ready to take your career to new heights and drive the future of space-age communication, apply now and join the MBRYONICS team as our Senior Linux Kernel Engineer .
