Job description

Requirements

Must have

• Solid experience in embedded firmware development for embedded devices (RTOS or Linux, peripherals, AXI/AHB, MMU, DMA) with focus on low‑level programming (C/C++).
• Experience in implementing security features in firmware: cryptographic signatures, secure boot, anti‑rollback, hardware root‑of‑trust.
• Proficiency in debugging at firmware/hardware level using JTAG, UART, ICE and diagnostic tools.
• Familiarity with NVMe/ATA command sets, and system‑level I/O integration.
• Experience with version control (e.g., Git) and collaborative development in R&D environments.

Nice to have

• Knowledge of Flash Translation Layer (FTL), wear‑leveling, garbage collection, ECC, implementation in mass storage devices (SSD/others).
• Familiarity with SSD controller SDKs and vendor‑specific cmds (TRIM/Secure Erase/firmware‑vendor extensions).
• Experience with embedded firmware on x86 platforms (Intel or AMD) in early‑boot contexts (UEFI/RTOS).
• Knowledge of scripting (Python) for test automation, telemetry analysis, and simulation of ransomware scenarios.
• Understanding of heuristics for anomaly detection (entropy, burst‑rate, process I/O patterns) and integration with system filters.

Responsibilities

• Design, develop, and implement embedded firmware for SSDs and next‑generation memory products (RTOS/Linux, AXI/AHB, MMU, DMA).
• Develop firmware modules for the integrated memory controller (IMC) of Intel/AMD CPUs.
• Collaborate with silicon, hardware, and R&D teams on architecture and specifications.
• Develop and integrate drivers for IP blocks, peripherals, storage interfaces (PCIe/NVMe, SATA, SCSI).
• Implement and test security mechanisms in firmware (secure boot with anti‑rollback, cryptographic signatures, trust chain).
• Extend Flash Translation Layer (FTL) with advanced functions (wear‑leveling, garbage collection, ECC, secure snapshots).
• Work with vendor reference stacks (Intel FSP/MRC or AMD AGESA).
• Perform low‑level debugging (ICE/JTAG/UART), root cause analysis, and corrective actions.
• Create and execute integration tests between hardware, firmware, and security modules.
• Contribute to coding standards, version control (e.g., Git), and technical documentation.
