Hardware Engineering Manager

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.

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 a highly technical, execution-oriented Hardware Engineering Manager to own the product lifecycle and system-level deployment of our disruptiveZeus GPU platform. Moving past legacyarchitectures, Bolt Graphics is redefining high-performance computing, advanced physics simulation (FP64), and real-time path tracing with a ground-up RISC-V controlled architecture thatoperatesas a standalone computing system.

In this role, you will bridge the gap between silicon architecture, system hardware design, and operations to deliver two critical form factors to market: high-densityPCIe Gen 5/6 accelerator cards featuring innovative user-expandable memory (LPDDR5X + DDR5 SO-DIMMs) and ultra-scalable2U HPC Server configurations. You will lead the hardware product definition, manage tier-1 ODM/EMS delivery, and drive the hardware ecosystemrequiredto displace legacy, power-hungry GPU clusters.

What you'll do:

Product Definition & Hardware Roadmap

• FormFactor Optimization: Own the PRD and hardware requirements for single/dual-chiplet PCIe accelerator form factors (e.g., Zeus 1c26/2c26) and multi-chip 2U rack-mount server architectures.

• Memory Subsystem Strategy: Drive product requirements around our unique, high-capacityexpandable memory subsystem, balancing the integration of on-board LPDDR5X with user-upgradable DDR5 SO-DIMM/DIMM slots to unlock up to 2.25TB per server node.

• Native Network Integration: Define the roadmap for our integrated, high-bandwidth communication fabrics,utilizingnative400GbE / 800GbE interfaces built directly into the accelerator toeliminatethe need for discrete NICs, loweringlatencyand TCO.

System Engineering & Infrastructure Co-Design

• Standalone Subsystem Readiness: Collaborate with firmware and platform teams to ensure the embedded RISC-V control processor seamlessly runs standalone Linux subsystems, including server management features like integrated BMC and IPMI.

• Thermal & Power Efficiency: Manage system trade-offs for highly efficient power targets (ranging from 120W single-slot boards up to 500W multi-chip server environments), ensuringoptimalbalance between air-cooled density and deployment in legacy data center infrastructures.

Execution, NPI & Operations Collaboration

• Silicon-to-System Execution: Drive cross-functional execution from recent chip tape-out through hardware validation, system-level NPI, and mass production.

• Supply Chain & Partner Engagement: Partner with hardware engineering, board layout, signal integrity teams, and ODMs to source components,optimizeBill of Materials (BOM) costs, and ensure manufacturing resilience for complex high-speed PCBs.

Qualifications:

Technical Competencies

• High-Speed Hardware Architecture: 5+ years of experience defining or engineering high-performance PCIe-based add-in cards (AIC) or complex serversystems. Deep understanding ofPCIe Gen 5.0 / 6.0 electrical integrity, form factor constraints, and signal routing.

• Memory & System Topology: Strong technical literacy in memory architectures (DDR5, LPDDR5X, or HBM) and an understanding of how large memory capacity scales performance in FP64 scientific simulations (e.g., electromagnetic wave simulations) and path tracing.

• Embedded & Networking Fundamentals: Familiarity with embedded processors (RISC-V/ARM), Linux-based system architectures, and network fabrics (Ethernet/InfiniBand)operatingat 400Gbps+.

Product Leadership & Execution

• Startup Agility with Enterprise Rigor: Proventrack recordof takingcomplex siliconor hardwarehardwareproducts from post-tape-out validation into full production.

• TCO Optimization: Strong business acumen with the ability to build data-driven Total Cost of Ownership (TCO) models, proving the cost and power benefits of Bolt’s architecture against legacy, high-wattage hardware clusters.

• Academic & Professional Background: BS/MS in Electrical Engineering, Computer Engineering, or a related hardware field. An MBA is highly valued to successfully bridge complex engineering milestones with customer commercialization strategy.

Preferred Qualifications

• Direct experience working on high-performance compute accelerators, GPUs, or server motherboards designed forrenderfarms and HPC centers.

• Experience navigating the hardware ecosystem transition from x86/Arm host controllers to alternative open architectures likeRISC-V.

• Familiarity with the mechanical and thermal constraints of fitting high-density, multi-slot accelerator boards into standard data center rack infrastructure.

Compensation Range: $200,000-$250,000per 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
