RTL Design​/Microarchitecture Engineer

Bolt Graphics is a semiconductor startup based in Sunnyvale, CA building the fastest and most efficient graphics processors. We pride ourselves on our first principles approach to solving problems. We are energized by our mission to reduce the barrier of entry for content creation and consumption. Our goal is to enable everyone to easily create, simulate and consume immersive experiences as vividly as they can imagine them.

• Be Fearless: Unmute yourself. Test boundaries and get proven right.
• Remain Adaptable: Stay comfortable in a continuously changing world. If you’re wrong, concede and move on.
• Educate Your Ego: Selflessly collaborate towards our shared purpose.

As an RTL Design / Microarchitecture Engineer, you will define and implement key microarchitectural components of our SoC/IP. You will work closely with architecture, verification, and physical design teams to deliver high-performance, scalable, and power-efficient designs.

• Define and develop microarchitecture specifications from high-level architecture requirements.
• Design and implement RTL (System Verilog/Verilog) for complex digital blocks.
• Drive performance, power, and area (PPA) optimizations at the RTL and microarchitecture level.
• Collaborate with verification teams to ensure high coverage and design correctness.
• Support integration of IPs into SoC-level environments.
• Work with physical design teams for timing closure, synthesis constraints, and floorplan-aware design.
• Debug and resolve issues during simulation, GLS, and silicon bring-up.
• Participate in design reviews, architecture discussions, and cross-functional planning.
• Contribute to design documentation and methodology improvements.

• Bachelor’s/Master’s degree in Electrical Engineering or related field.
• 5–10 years of experience in RTL design and microarchitecture.
• Strong expertise in:
  • Performance optimization and pipelining techniques.
  • Experience with simulation and debugging tools such as:
  • Synopsys VCS/Cadence Xcelium.
  • Familiarity with synthesis and timing concepts (e.g., using Synopsys Design Compiler).
  • Strong understanding of digital design fundamentals (FSMs, pipelines, caches, memory interfaces).
  • Experience working in ASIC/SoC development environments.

• Experience in one or more domains:
  • CPU, GPU, AI/ML accelerators, networking, or high-speed data processing.
• Knowledge of memory subsystem design (SRAM, cache hierarchies, coherency).
• Familiarity with low-power design techniques (clock gating, power domains).
• Exposure to formal verification or linting tools.
• Experience with GLS, SDF annotation, and silicon debug.
• Understanding of hardware-software interaction (firmware, drivers).

$160,000–$220,000 per year (California). This range represents the anticipated base pay for this role based in California; the final offer may vary based on qualifications, experience, and location.
