Senior Embedded Firmware Engineer - AI Accelerator

Mirafra Technologies; Sunnyvale (CA); On-site; USD 160,000 - 260,000; Full time

Job summary

Mirafra Technologies in Sunnyvale, CA, seeks an embedded firmware engineer for AI accelerator silicon. You will own firmware architecture, boot/init, device drivers, memory controllers, and the on-device runtime from first silicon to production.

You will lead silicon bring-up, debug RTL-vs-firmware issues, and collaborate with RTL/architecture teams to shape register maps and HW/SW contracts. Strong troubleshooting across the stack is essential.

Qualifications

• Embedded firmware experience
• Hardware-software integration
• RTL-firmware debugging
• HAL and register-access knowledge
• On-device runtime experience
• Collaboration with RTL/architecture teams
• Debug techniques across stack (JTAG, logic analyzers)

Responsibilities

• Firmware for AI accelerator silicon, covering datapath engines, DMA, and memory controllers.
• Own firmware architecture: boot/init, device drivers, command/queue dispatch, interrupts, DMA.
• Lead silicon bring-up: first-power tests, RTL–firmware debug, register-level verification.
• Build and maintain HAL and register-access layers against evolving RTL.
• Implement on-device runtime: workload scheduling, memory management, host synchronization.
• Co-develop with RTL/architecture teams to influence register maps, interrupt models, HW/SW contracts.
• Debug across stack with logic analyzers, JTAG, on-chip trace; correlate firmware to RTL simulations.
