Your Team Your Impact

What You Can Expect

RISC-V MCU / SoC Integration Ownership

• Lead integration of an embedded RISC-V core (e.g. SiFive E24 Core) into chip validation environments
• Define MCU subsystem architecture: memory map boot flow and execution environment
• Integrate and validate system interconnect (AHB/AXI-lite) and memory hierarchy (ROM/SRAM)
• Implement interrupt architecture using PLIC and CLINT

Firmware Development for PHY Validation

• Develop bare-metal and RTOS-based firmware for PHY/IP control and bring-up
• Implement calibration training and tuning algorithms for high-speed interfaces
• Build reusable firmware frameworks for:
  • Register-level control abstraction
  • Test sequencing and automation
  • Logging diagnostics and error handling

System-Level Bring-Up & Debug

• Lead silicon and pre-silicon bring-up using embedded firmware
• Debug cross-domain issues across hardware firmware and PHY behavior
• Enable rapid iteration of initialization configuration and recovery flows
• Drive root-cause analysis for system-level failures

Validation Automation & Framework Integration

• Integrate RISC-V firmware into existing PHY validation automation framework
• Enable unified validation across simulation emulation/FPGA and silicon
• Develop firmware-driven test scenarios replacing or complementing external stimulus
• Build infrastructure for automated test execution and result collection

Validation Strategy & Coverage Expansion

• Transition validation methodology from directed external tests to software-driven closed-loop validation
• Define and implement coverage for:
  • Functional PHY behavior
  • Corner cases and stress conditions
  • Recovery and error handling scenarios
• Ensure reusability of validation content across programs and platforms

Cross-Functional Collaboration

• Partner with RTL teams on SoC integration and interface definitions
• Work with validation teams to align firmware-driven test strategies
• Collaborate with architecture teams to define scalable validation platform direction
• Support system-level debug across hardware/software boundaries

Infrastructure & Toolchain Ownership

• Maintain RISC-V toolchain environment (GCC linker scripts startup code)
• Support debug infrastructure (JTAG OpenOCD GDB workflows)
• Drive automation for firmware build deployment and regression execution

What Were Looking For

Must Have

• 8 years of experience in embedded systems firmware or SoC development
