Company

hirify.global is a semiconductor startup building high-performance and energy-efficient graphics processors for immersive content creation, simulation, and consumption.

What you will do

• Own the end-to-end hardware development lifecycle for graphics compute platforms, GPU servers, and high-speed PCIe graphics form factors.
• Drive system architecture trade-offs across GPU packaging, PCB routing density, thermal mechanics, and high-density power delivery networks.
• Design and optimize PCIe Gen 5/Gen 6 and scale-up interconnect topologies, including fabrics such as NVLink, Infinity Fabric, and UA Link.
• Collaborate with silicon, signal and power integrity, thermal, and mechanical teams on board stack-ups, low-loss materials, and multi-phase power zones.
• Lead JDM/ODM engineering partners through layout execution, platform bring-up, hardware debugging, and component-level failure analysis.
• Govern design reviews and DFX compliance to support EVT/DVT validation and high-yield high-volume manufacturing.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related discipline.
• 8+ years of hardware design experience shipping graphics hardware, GPU motherboards, or parallel compute accelerator boards.
• Hands-on experience with PCIe Gen 5/6 and high-speed 112G/224G PAM4 SerDes architectures.
• Strong knowledge of high-frequency PCB constraints, via optimization, signal and power integrity, and power delivery networks for high di/dt loads.
• Proficiency with EDA tools such as Cadence Allegro or OrCAD and physical-design simulation tools.
• Experience directing overseas ODM engineering teams through architecture, layout, and laboratory hardware triage.

Nice to have

• Experience with Open Compute Project standards or multi-GPU form factors.
• Familiarity with CXL or scalable interconnect fabrics.
• Experience with liquid cooling or phase-change thermal infrastructure.
• Hands-on use of oscilloscopes, VNAs, BERTs, or similar high-speed validation equipment.

Culture & Benefits

• Medical, dental, and vision premiums covered at 100%.
• Stock options and a 401(k) match.
• Work-from-home equipment reimbursement.
• Culture centered on fearlessness, adaptability, collaboration, professionalism, integrity, and respect.
