What We OfferThis is an exciting opportunity for a highly skilled and experienced Senior Firmware Engineer to work at the intersection of hardware and software - bringing up new platforms, developing bootloaders and Linux BSPs, and contributing to FPGA gateware for Opengear's next-generation console server products. You will work hands-on with ARM and FPGA-based SoC platforms (Xilinx Zynq, Marvell Armada), developing the low-level firmware that makes our hardware work - from the first boot instruction through to a fully functional Linux system. This is not application-level development; this is bare-metal, bootloader, kernel, and FPGA territory. This is a hands-on, high-impact role requiring strong technical depth in embedded Linux systems, cross-functional collaboration with hardware and manufacturing teams, and the ability to work independently across multiple platform architectures.
What You Will Do - Bring up new hardware platforms from scratch - from bootloader porting through to a bootable Linux system with validated peripherals.
- Develop, port, and maintain bootloaders (U-Boot, Coreboot, or equivalent) including device tree authoring, flash layout design, and boot chain configuration.
- Build and maintain Yocto/BitBake BSP layers - machine configurations, kernel recipes, device driver recipes, and rootfs image definitions.
- Configure, patch, and debug Linux kernels for embedded platforms - including device tree, driver enablement, and kernel module development.
- Write and maintain Linux device drivers and platform drivers for custom hardware (serial controllers, network switches, SPI/I2C devices, LEDs, sensors, TPM).
- Develop embedded firmware in Rust for platform tools and bootloader components.
- Create and maintain manufacturing self-test software to validate hardware during production.
- Implement and maintain secure boot chains including TPM integration, boot signing, and firmware verification.
- Collaborate closely with hardware, systems, and manufacturing teams on PCB bring-up, schematic review, and hardware validation.
- Participate in design reviews, code reviews, and contribute to technical documentation.
Who You Are and What You Bring- 5+ years of hands-on experience in embedded Linux firmware development - specifically at the kernel, BSP, and bootloader level (not application-level Linux).
- Strong C programming skills applied at the bootloader and kernel level (U-Boot patches, kernel driver modifications, Coreboot, bare-metal). Production experience with U-Boot or equivalent bootloader - porting to new platforms, device tree authoring, flash layout, boot chain bring-up.
- Production experience with Yocto Project / BitBake / OpenEmbedded - writing recipes, managing BSP layers, machine configurations, cross-compilation.
- Hands-on Linux kernel work - kernel configuration, device tree authoring and modification, enabling/patching drivers, udev rules.
- Experience with ARM SoC platforms (e.g., Marvell Armada, NXP i.MX, Xilinx Zynq, TI Sitara).
- Board bring-up experience - taking a new PCB from first power-on through to a booting Linux system.
- Familiarity with hardware interfaces: PCIe, SPI, I2C, UART, USB, network switches (DSA), SFP modules.
- Experience with hardware debugging tools - serial console, JTAG, oscilloscopes, logic analyzers.
- Proficiency with Git version control and CI/CD systems.
- BS/MS in Electrical Engineering, Computer Engineering, or equivalent hands-on experience.
Highly Desired: - Rust programming experience - particularly applied to embedded or systems-level problems (professional, open source, or substantial personal projects).
- FPGA development experience - VHDL or Verilog gateware design, simulation (GHDL, ModelSim), synthesis tools (Xilinx Vivado, Quartus).
- Develop and maintain FPGA gateware (VHDL) for serial port multiplexing and peripheral interfaces, including simulation and test.
- Develop and maintain CI/CD pipelines (Jenkins) for automated firmware builds, tests, and release management.
- Linux device driver development - writing or significantly modifying character, platform, or network drivers.
- TPM and secure boot experience - PCR measurement, provisioning, boot signing, Intel BootGuard or ARM TrustZone/TF-A.
- Embedded Controller (EC) or auxiliary microcontroller firmware development.
- Experience with Coreboot or other x86 firmware (UEFI/BIOS alternative).
- Manufacturing test software development - hardware self-tests, production validation.
- Jenkins pipeline development or equivalent CI/CD automation experience.
- Python scripting for build tools, test automation, or hardware validation.
Nice to Have: - Familiarity with cellular modem integration (ModemManager, QMI, AT commands).
- Familiarity with RAUC or similar OTA update frameworks.
- Contribution to open-source bootloader or kernel projects.
- Experience working with contract manufacturers and production test environments.
- Experience with network switch configuration (DSA framework, switchdev).
