Staff Embedded Firmware & System Software Engineer — Platform Controller and SoC Stack
Quick Summary
8–10 years of professional experience in embedded firmware and/or system software development, primarily using C. Meaningful hands-on experience with modern C++ or Rust.
This is a staff-level engineering opportunity focused on building the software stack that turns next-generation silicon into a production-ready computing platform. You’ll work across embedded firmware, platform controllers, boot software, kernel drivers, PCIe, IOMMU, DMA, and system-level interfaces. The role combines low-level software development with first-silicon bring-up, hardware debugging, and architecture-level problem solving. You’ll work closely with hardware and design teams to diagnose complex interactions between silicon, firmware, operating systems, and high-speed interconnects. Your work will directly influence platform reliability, performance, security, and the ability of operating systems to run effectively on new hardware. The environment is highly technical, fast-moving, and oriented toward engineers who enjoy solving difficult problems across hardware and software boundaries.
-
Design, implement, and maintain Zephyr RTOS firmware for platform management controllers, including device drivers, subsystem integrations, and application-level services.
-
Develop high-quality drivers aligned with Zephyr's driver model, including devicetree bindings, Kconfig configuration, initialization levels and priorities, and device APIs.
-
Bring up and debug PCIe links on first silicon, investigating link training, LTSSM progression, lane reversal and polarity, equalization, and speed and width negotiation issues.
-
Implement and maintain PCIe host controller and endpoint drivers, including enumeration, configuration space, BAR allocation, MSI/MSI-X interrupt routing, AER, error handling, ASPM, and link power states.
-
Configure, validate, and troubleshoot IOMMU functionality, including address translation, DMA remapping, device isolation domains, page-table management, and fault reporting and recovery.
-
Develop system software throughout the boot and runtime path, including bootloaders, firmware-to-OS handoff, ACPI or device-tree descriptions, kernel drivers, and DMA and memory-management interfaces.
-
Debug DMA correctness, memory access, and cache coherency issues end to end, tracing problems from device transactions through translation and into system memory.
-
Perform post-silicon bring-up activities including first-boot debugging, clock and reset validation, bus enumeration, and diagnosis of hardware-versus-firmware issues.
-
Use JTAG/SWD, ETM/ITM trace, protocol analyzers, logic analyzers, and other low-level debugging tools to investigate intermittent, timing-sensitive, and multi-master failures.
-
Translate hardware specifications, register maps, and silicon behavior into correct, testable, maintainable software.
-
Collaborate closely with hardware, RTL, architecture, and design teams to resolve complex silicon and system-level issues.
-
Contribute to software architecture, engineering standards, code reviews, and development practices across the platform software stack.
-
Evaluate and apply modern approaches, including AI-assisted development tools, to improve software engineering productivity and quality.
