• Work closely with silicon partners (Intel/AMD/Qualcomm) for firmware integration
• Perform low‑level debugging across firmware, hardware, and OS layers
• Write efficient and reliable embedded code in C/C++
• Enable key features such as power management, security (Secure Boot, TPM), and system configuration
• Analyze system logs, firmware traces, and hardware signals to troubleshoot issues
• Collaborate with Windows and driver teams to ensure seamless platform functionality
• Participate in design discussions, code reviews, and firmware releases

Required Qualifications

• 5+ years of experience in UEFI/BIOS or embedded firmware development
• Strong proficiency in C/C++ programming in low‑level environments
• Hands‑on experience with platform bring‑up and system debugging
• Solid understanding of boot architecture, memory, and hardware interfaces
• Experience with debugging tools (JTAG, oscilloscopes, logic analyzers)
• Familiarity with ACPI, PCIe, USB, SPI, I2C protocols
• Experience working with Intel/AMD/ARM‑based platforms
• Strong analytical and problem‑solving skills

Preferred Qualifications

• Experience with consumer devices (laptops/tablets), especially Surface‑like products
• Exposure to Windows platform internals and driver interaction
• Knowledge of firmware security (Secure Boot, TPM, measured boot)
• Experience in power and performance optimization
• Familiarity with full product lifecycle from development to production
