Software Engineer

We are seeking a highly skilled and motivated Bootloader Engineer with strong expertise in ARM64 platform bring-up and secure bootloader development for SONiC-based networking operating systems on the ARMv8 or ARMv9 SoC. In this role, you will design, develop, and optimize bootloaders (U-Boot or UEFI) and trusted firmware components, enabling secure and efficient system initialization, firmware chain-of-trust, and FIT or other combined image deployment on high-performance ARM platforms. You will collaborate closely with hardware / FPGA, Linux Kernel, and SONiC software teams to integrate secure and non-secure boot flows, set up secure signing server infrastructure and signing workflows, enable TPM/eHSM-based measurable boot, and ensure platform integrity through attestation and reliable recovery mechanisms. This position requires strong knowledge of ARM64 architecture, boot flow, memory initialization, storage management and low-level board firmware development for hyperscale data center environments.

Key Responsibilities

• :Design, develop, and optimize U-Boot bootloaders and trusted firmware for ARM64 platforms
• .Implement secure and non-secure boot flows integrating with TPM/eHSM for measured boot and attestation
• .Set up and maintain secure signing server infrastructure and signing workflows for secure boot, including key provisioning, certificate management, access control, audit logging, and integration with firmware release pipelines
• .Develop and maintain FIT image (Flattened Image Tree) for SONiC firmware packaging and boot chain management
• .Work with hardware and software teams to ensure reliable bootloader-to-kernel transitions, memory initialization (DDR tuning), and peripheral bring-up
• .Contribute to secure firmware digital signing, verification, rollback and update pipelines
• .Validate platform boot performance /time, reliability, and compliance with secure manufacturing workflows
• .Document design, test procedures, and bring-up results for internal and customer release milestones
