CPU Power-Management Design Engineer

The Role SiFive is looking for hardware engineers who are passionate about designing industry‑leading CPU and interconnect IP to help drive the tidal wave of adoption of RISC‑V as the architecture of choice for SOC designs across a broad variety of vertical applications. As a Power‑Management/Reset/Clock Micro‑Architect and RTL Design Engineer you will be part of a team creating highly configurable IP and improving time‑to‑market by designing hardware with the agility of software development. Responsibilities Work with the architecture team to understand and define power management requirements. Architect, design and implement core clocking, reset and power‑management solutions. Develop microarchitecture and write specifications, ensuring knowledge sharing through clear documentation. Perform initial sandbox verification and collaborate with the design‑verification team to create and execute thorough verification test plans. Work with the physical‑implementation team to implement and optimise physical design to meet frequency, area and power goals. Collaborate with software teams to enable and optimise power‑management features. Requirements 3+ years of recent industry experience in CPU and SoC clocking, reset, and power‑management logic designs. Experience in high‑performance, energy‑efficient CPU and SoC designs. Expertise in CPU and SoC clocking, reset design, and power management, including: Reset control and design strategies: clock distribution, dynamic clocking, clock gating, clock boundary crossing strategies. Power‑state definition and management and Power Management Unit (PMU) design. Dynamic and static power reduction techniques: retention, power‑up/down sequencing. Dynamic voltage and frequency scaling (DVFS) and diode‑current mitigation strategies. Understanding of DFT, MBIST, debug and error handling in CPU designs. Power‑aware simulation. Proficiency with hardware (RTL) design in Verilog, SystemVerilog, or VHDL. Good understanding of RTL quality checks such as Lint, CDC, RDC. Hands‑on experience with Spyglass is a plus. Attention to detail and focus on high‑quality design. Ability to work well with others and belief that engineering is a team sport. Knowledge of at least one object‑oriented or functional programming language. Background of successful CPU or SoC development from architecture through tape‑out. BS/MS degree in EE, CE, CS or related technical discipline, or equivalent experience. Nice to Have Experience with AMBA Interconnect Protocols (AXI, AHB, APB). Experience with AMBA Low Power Protocol Interface (P‑channel, Q‑channel). Experience with Scala/Chisel, Bluespec or other language/DSL for configurable hardware. Knowledge of RISC‑V architecture. Experience with Git, GitHub, Jira, Confluence. Pay & Benefits Base Pay Range: $158,760.00–$194,040.00 (depending on location, experience, and skills). In addition to base pay, the role may be eligible for variable/incentive compensation and equity. Comprehensive benefits include healthcare, retirement plans, paid time off, and more. Additional Information Position requires successful background and reference checks and proof of right to work in the United States. Eligibility for export‑controlled technology access may be required. SiFive is an equal‑employment‑opportunity employer. SiFive is proud to be an equal‑employment‑opportunity workplace.
