Senior PCB Layout Engineer

Senior PCB Layout Engineer Overview

Fractile is at the forefront of developing silicon, systems, and software that aim to revolutionize AI by enabling the execution of advanced models at unprecedented speeds and reduced costs. We are expanding our exceptional team, which encompasses both hardware and software expertise, to meet the growing demand for our products.

We are currently looking for a Senior PCB Layout Engineer who will be responsible for delivering intricate, high-speed, and high-power PCB designs. This position also entails managing the creation, validation, and ongoing management of PCB libraries, playing a vital role in ensuring the electrical performance, manufacturability, and long-term design quality of multiple products.

Key Responsibilities

• Create PCB layouts for complex, multi-layer boards that support high-speed digital and high-power circuits.
• Own the component placement, routing, and constraint implementation from concept to manufacturing release.
• Collaborate closely with hardware designers to resolve layout-driven electrical and mechanical trade-offs.
• Route high-speed interfaces such as DDR, PCIe, Ethernet, USB, and SerDes-based links, applying controlled impedance routing and differential pair tuning.
• Implement SI-aware stack-ups and routing strategies to minimize crosstalk and signal loss.
• Design high-current power paths, including VRMs, DC-DC converters, and power planes, optimizing copper distribution and plane structures.
• Support thermal performance through effective copper pours, stitching vias, and planning heatsink interfaces.
• Create, validate, and maintain schematic symbols, PCB footprints, and 3D models, ensuring compliance with IPC standards.
• Oversee library quality, version control, naming conventions, and release processes.
• Collaborate with engineering, manufacturing, and supply chain teams to ensure component accuracy and lifecycle readiness.
• Participate in schematic and layout design reviews, as well as SI/PI discussions, working with engineers to implement simulation-driven layout constraints.
• Generate manufacturing deliverables such as Gerbers, ODB++, IPC drawings, and pick-and-place data.
• Assist in board bring-up and debugging by implementing layout ECOs and resolving layout-related manufacturing or assembly issues.

Qualifications & Experience

• A diploma, Bachelor’s degree, or equivalent experience in Electronics, Electrical Engineering, or a related field.
• At least 7 years of professional PCB layout experience.
• Proven experience with high-speed digital and high-power PCB designs.
• Hands-on experience in creating and maintaining PCB libraries for production hardware.
• Proficiency in PCB layout tools such as Siemens Xpedition, Altium Designer, or Cadence Allegro.
• Experience with high-speed routing techniques for interfaces like DDR, PCIe, Ethernet, USB, and SerDes.
• Knowledge of high-current and power integrity layout techniques, particularly for multi-layer PCB stack-ups (10+ layers preferred).
• Exceptional attention to detail and a strong ownership mindset regarding design quality and library integrity.
• Effective communication skills to collaborate with hardware, mechanical, and manufacturing teams.
• Ability to manage multiple designs and revisions simultaneously.

Preferred Experience (Nice to Have)

• Experience with SI/PI simulation-informed layouts.
• Familiarity with EMI/EMC-aware layout practices.
• Experience with HDI, fine-pitch BGAs, and advanced PCB technologies.
• Experience with AI accelerator or HPC hardware.
