SiFive seeks a hardware design technical lead focused on debug, trace and profiling IP for SOC designs across a broad variety of vertical applications. The role designs industry‑leading debug, trace and profiling hardware, leveraging the Chisel hardware construction library in Scala to build highly configurable generators. Enhanced collaboration with customers, partners, tools vendors and the RISC‑V International Association will shape the future of debug strategy.

• Design the best debug, trace, and profiling hardware in the world based on open RISC‑V and Tile Link architectures.
• Master designing hardware as configurable generators in a domain‑specific software language for elaborating digital logic.
• Work in a fast‑paced dynamic environment to bring new hardware IP to market quickly, with high quality and exceptional performance.

• Architect, design and implement debug, trace and profiling hardware.
• Work with architecture, performance, software and hardware teams in architecture/microarchitecture exploration and specification.
• Implement RTL generators so elements self‑configure to optimally design‑in extensive configurability as a first‑class consideration.
• Integrate new design content into SiFive’s Chisel/FIRRTL framework and contribute to improvements that enable automatic configuration/generation of documentation, verification test benches and tests, and packaged software.
• Perform initial sandbox verification and work with the design verification team to create and execute thorough verification test plans.
• Ensure knowledge is shared via creation and maintenance of great documentation and by participating in a culture of collaborative design.

• Knowledgeable in debug, trace and profiling architecture and concepts.
• Knowledgeable in debug interfaces, JTAG, cJTAG.
• Knowledgeable in CPU architectures, power management and SoC design.
• Experience in debugging tools and profiling methods.
• Proficiency with hardware (RTL) design in Verilog, System Verilog, or VHDL.
• Attention to detail and a focus on high‑quality design.
• Ability to work well with others and a belief that engineering is a team sport.
• Knowledge of at least one object‑oriented and/or functional programming language.
• Knowledge of one or more of:
  Chisel/Scala, RISC‑V architecture, Git/Jira/Confluence is a plus.
• 7+ years of industry experience leading and directly contributing to architecture, microarchitecture and RTL design for debug/trace/profiling hardware for high‑performance processors.
• MS/PhD in EE, CE, CS or a related technical discipline.
