Senior Hardware Engineer

Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale.

We are seeking aHardware Electronics Design Engineer to design, develop, and validatehigh-speedand high-power electronic systems. This role involves schematic design, PCB development, signal and power integrity, and hands‑on bring‑up of complex hardware. The engineer will work closely with system, mechanical, firmware, and manufacturing teams to deliver reliable, high‑performance products from concept through production.

The ideal candidate has deep experience with high-speed interfaces and power delivery, and is comfortableowning designs through debugging, validation, and manufacturing release.

• Design and develop high-speed (PCIe/Ethernet) electronic circuits and systems
• Design power delivery networks (PDN) including DC-DC converters, multi‑phase VRMs, and protection circuits
• Create schematics, BOMs, and design documentation for complex PCBs
• Lead board-level architecture decisions including power topology, interface selection, and component choice
• Work with PCB layout engineers to ensure proper stack‑ups, routing, and return paths
• Address thermal considerations in collaboration with mechanical and thermal teams
• Lead board bring‑up, debug, and root‑cause analysis of hardware issues
• Use lab equipment (oscilloscopes, network analysers, power analysers) to validate performance
• Support compliance, reliability, and environmental testing
• Support DFM/DFT reviews and transition designs into manufacturing

• Diploma, Bachelor’s or Master’s degree in Electrical or Electronic Engineering, or equivalent experience
• 7+ years of experience in hardware electronics design
• Experience taking designs from concept through production

• Power electronics and PDN design (buck/boost converters, VRMs, protection)
• Signal integrity (SI) and power integrity (PI) principles
• Schematic capture and PCB tools (Xpedition, Altium, Cadence, or equivalent)
• Hardware debug and lab instrumentation

• Experience with multi‑layer high-speed PCBs (10+ layers)
• Familiarity with SI/PI simulation tools
• Experience with compliance testing (EMI/EMC, safety)
• Experience with AI accelerator or HPC hardware
• Thermal Management:
  Knowledge of techniques to manage heat dissipation in high‑power systems
