Company

hirify.global is a semiconductor startup building high-performance, energy-efficient graphics processors for content creation, immersive experiences, scientific simulation, and real-time path tracing.

What you will do

• Own product requirements and the hardware roadmap for single- and dual-chiplet PCIe accelerator cards and multi-chip 2U rack-mounted server architectures.
• Define the expandable memory strategy using onboard LPDDR5X and user-upgradable DDR5 SO-DIMM/DIMM slots, supporting up to 2.25 TB per server node.
• Develop the roadmap for integrated 400GbE and 800GbE communication fabrics and native networking capabilities.
• Coordinate firmware and platform teams on standalone Linux subsystems, embedded RISC-V control, BMC, and IPMI functionality.
• Manage thermal and power trade-offs across 120W single-slot boards and 500W multi-chip server environments.
• Drive execution from post-tape-out validation through system NPI, mass production, ODM/EMS delivery, component sourcing, BOM optimization, and manufacturing resilience.

Requirements

• 5+ years defining or engineering high-performance PCIe add-in cards or complex server systems.
• Deep understanding of PCIe Gen 5.0/6.0 electrical integrity, signal routing, and form-factor constraints.
• Strong knowledge of DDR5, LPDDR5X, or HBM memory architectures and their impact on FP64 simulation and path-tracing performance.
• Familiarity with RISC-V or ARM processors, Linux-based system architectures, and 400Gbps+ Ethernet or InfiniBand fabrics.
• Experience taking complex silicon or hardware products from post-tape-out validation into full production.
• BS/MS in Electrical Engineering, Computer Engineering, or a related hardware field; MBA experience is highly valued.

Nice to have

• Experience with HPC accelerators, GPUs, or server motherboards for render farms and HPC centers.
• Experience transitioning from x86/Arm host controllers to open architectures such as RISC-V.
• Knowledge of mechanical and thermal constraints for dense, multi-slot accelerator boards in standard data-center racks.

Culture & Benefits

• First-principles problem solving and a mission focused on reducing barriers to content creation and consumption.
• Values include fearlessness, adaptability, and selfless collaboration.
• Medical, dental, and vision premiums covered at 100%.
• Stock options, 401(k) matching, and work-from-home hardware.
• Inclusive workplace centered on professionalism, integrity, and respect.
