Ampstek; Charlotte (NC); On-site; USD 120,000 - 160,000; Full time

Job summary

Ampstek is seeking an embedded Linux BSP engineer for the AST2700 platform in Charlotte. You will lead board bring-up, kernel configuration, and device-tree work for ARM SoCs, focusing on AST2700. The role requires developing low-level drivers and integrating firmware components with Root of Trust and BIOS management.

You will collaborate across teams to ensure clean handoffs and provide hardware context for security reviews, with strong emphasis on I2C/SPI and Yocto/OpenEmbedded workflows.

Qualifications

• Proven experience in embedded Linux BSP development, specifically in board bring-up, kernel configuration, and device tree authoring for ARM SoCs, preferably ASPEED AST2700.
• Strong skills in low-level bus driver development, particularly I2C and SPI, with a focus on debugging and protocol confirmation.
• Experience with Yocto/OpenEmbedded, including the ability to create and modify meta-layer recipes and configurations.
• Experience with firmware integration processes, including Root of Trust and BIOS management.
• Ability to work collaboratively across teams, ensuring effective communication and context sharing.
• Experience with BMC tools is a deal-breaker for this role.

Responsibilities

• Lead the bring-up of embedded Linux BSP, including kernel configuration and device tree authoring for ARM SoCs, with a focus on ASPEED AST2700.
• Develop and debug low-level bus drivers (I2C, SPI, eSPI) essential for EC interface bring-up.
• Contribute to Yocto/OpenEmbedded by authoring meta-layer recipes, machine configurations, and kernel bbappend files for ASPEED targets.
• Integrate firmware components, including Root of Trust, signing chain, and BIOS SPI flash management.
• Collaborate with cross-functional teams to ensure clean handoff of build artifacts and provide necessary hardware context for security reviews.
