About the role

Key responsibilities & impact

Develop embedded platform software supporting processor control, power‑management flows, and ASIC state coordination
Implement and integrate secure boot orchestration components, cryptographic validation routines, and platform trust enforcement
Design, implement, and bring up low‑level drivers, HAL layers, diagnostics, and platform initialization software
Work extensively in virtual development environments (simulation, emulation, virtual platforms, FPGA prototypes) before hardware availability
Work with and oversee subcontract suppliers responsible for custom bootloader and early‑boot software development
Review, validate, and integrate supplier deliverables (bootloaders, BSP components, startup sequences) into the platform software stack
Collaborate with OS and BSP vendors to integrate and configure RTOS components
Debug and root‑cause hardware/software interaction issues
Work within pipelined build and test development environments (e.g., automated build systems, CI/CD pipelines, continuous testing frameworks)
Identify opportunities to optimize development workflows, improve efficiency, and introduce innovative tools or methods
Document designs, contribute to coding standards, and support cross‑functional integration activities
Mentor junior engineers and contribute to a positive, collaborative team dynamic
