Our goal is to enable everyone to easily create, simulate and consume immersive experiences as vividly as they can imagine them.

Our Values

• 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.

About the role:

We are looking for an experienced and highly motivated Lead Vector Compute Architect to lead the architecture definition and technical direction for Bolt’s next-generation GPUs. The ideal candidate will have strong expertise in data parallel compute unit architecture development, performance modeling, data path integration, and cross-functional collaboration across hardware, software, and systems teams.  

This role involves defining scalable and high-performance architectures for advanced compute workloads including graphics, HPC, and system management. This role is on-site and requires someone to be local to the Bay Area. 

What you'll do:

• Define data parallel microarchitecture satisfying ISA constraints. 

• Drive architecture tradeoff analysis for performance, power, area, bandwidth, latency, and scalability.  

• Develop and review system architecture specifications, interface definitions, and microarchitecture requirements.  

• Collaborate with RTL, verification, physical design, firmware, software, and system teams throughout the development cycle.  

• Lead performance modeling, workload analysis, and bottleneck identification using C/C++/SystemC or similar modeling environments.  

• Define memory hierarchy, coherency architecture, and cache structures.  

• Work closely with verification teams to define architectural test plans and validation strategies.  

• Support silicon bring-up, debug, performance tuning, and post-silicon optimization.  

• Contribute to long-term technology and product roadmap planning.  

Qualifications:

• Strong understanding of modern data parallel microarchitectures and subsystem integration.  

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.  

• 6+ years of experience in modern data parallel microarchitecture including: 

• Workload characterization and profiling 

• Performance modeling 

• Out-of-order data dependency and control 

• Utilization / occupancy optimization 

• High-performance architecture design techniques

Experience with one or more of the following:  

• CPU/GPU/NPU architectures  

• NoC/interconnect architectures  

• Cache coherency protocols (CHI/ACE/CXL)  

• High-speed interfaces (PCIe, UCIe, Ethernet)  

• Memory systems (DDR, LPDDR, HBM, GDDR)  

• Power, performance, and area optimization  

• Strong knowledge of RTL development and verification methodologies.  

• Experience with architecture modeling and performance analysis tools.  

• Familiarity with firmware/software interaction in complex SoC systems.  

• Excellent problem-solving, communication, and leadership skills.   

Compensation Range: $250,000–$350,000 per year (California). This range represents the anticipated base pay for this role; the final offer may vary based on qualifications, experience, and location.

Benefits:

• Medical, Dental, & Vision - 100% covered premiums
• Equity - Stock Options
• 401(k) match
• WFH Hardware
