Position: Yocto Migration Engineer (CE60ST RM 4465)

Scope

Migration of a heterogeneous multi-architecture embedded ecosystem from Yocto Project 5.0 (Scarthgap) to Yocto Project 6.0 (Wrynose) LTS, integrating SCP (ARM Cortex-M55), RISC-V processors, and flexible 32-bit/64-bit target platform selection via BitBake Multi-Config (multiconfig) and multilib.

Key Responsibilities & Requirements

• Yocto v5.0 to v6.0 (Wrynose) LTS Migration:
• Migrate large-scale custom BSPs, distros, and multi-architecture layers from Scarthgap to Wrynose.
• Address upstream breaking changes including systemd default migration, explicit pkgconfig exposure rules, and updated files/wic/ kickstart pathing.
• Open-Source Recipe Compliance:
• Write and refactor recipes adhering strictly to OpenEmbedded coding standards (proper SPDX licensing, checksum verification, Upstream-Status patch tracking, and standard class inheritance).
• BitBake Multi-Config Architecture:
• Design and maintain parallel build pipelines using BitBake’s multiconfig framework (BBMULTICONFIG)



to build distinct target environments from a single invocation.
• Manage cross-target artifact piping and firmware packaging dependencies using mcdepends.
• Heterogeneous Target & Coprocessor Integration:
• SCP Firmware (ARM Cortex-M55): Build, package, and integrate System Control Processor (SCP) firmware images using baremetal/newlib toolchains.
• RISC-V Processors: Configure and build bear metal firmware for RISC-V application and co-processing targets.
• Versatile 32-bit / 64-bit Target Platform Support:
• Architect distro configurations that allow seamless switching or simultaneous compilation of either 32-bit or 64-bit binaries for the primary application target, alongside multilib support to execute legacy 32-bit user-space applications on 64-bit OS kernels where required.
• Build Performance Optimization & Target Validation:
• Tune BitBake concurrency, shared state (SSTATE_MIRROR) caching infrastructures, and prune unused fe
