Job Description

Looking for your next career challenge? We seek an experienced Electronics Engineer specializing in PCB Signal / Power Integrity to join Arm's Packaging, Boards and Multiphysics team. You will be involved with systems that incorporate Arm processors, focusing on SI and PI analysis of System-on-Chip (SoC) to board integration. We are working at the forefront of embedded compute focusing on developing hardware platform prototypes to validate and demonstrate Arm's latest IP products.

Responsibilities:

Collaborate with engineering teams across geographies to perform system-level signal integrity and power integrity including silicon, package, and board. Work alongside the chip packaging and PCB design teams, to support routing strategies, design rules and layer optimization to ensure optimal performance, reliability, and cost-effectiveness. Lead system level signal integrity analysis and propose solutions to meet interface timing. Collaborate with electrical validation for post silicon correlation. Perform board/system-level power delivery network AC+DC simulation for low-voltage/high-current supplies.

Required Skills and Experience:

• 8+ Years of Experience with strong understanding of hardware architectures, electronics and embedded compute
• Deep knowledge of high-speed Signal and Power Integrity and timing analysis techniques, across silicon, package and board. Electromagnetic modeling of 3-D structures
• Expertise in SI analysis of high density SoC's. Optimize signal paths for signal quality and prevent signal degradation. Verify routing strategy with a particular stack-up and rule set
• Deep understanding of multi-port matrixes (S, Y, Z parameters)
• Detailed understanding of high-speed interface standards e.g. PCIe Gen 5/6/7 and DDR4/5 and LPDDR4/5/5x/6 memory technologies, USB, Ethernet
• Familiarity with different IC packaging technologies and their impact on PCB design to ensure seamless integration of SoCs, ensuring proper signal routing and power delivery
• Experience of collaborating with chip packaging teams. Ability to influence SoC device pin-outs for performance optimization, routing feasibility and layer trade-off analysis
• Understanding of the PCB fabrication process (PTH and HDI), stackup/via topologies and substrate materials
• Proficiency in the use of Signal Integrity tools from ANSYS, Siemens EDA and PCB Layout specifically Cadence Allegro PCB suite and OrCAD CIS
• Good communication and interpersonal skills. Positive can-do attitude and attention to detail

"Nice To Have" Skills and Experience :

Experience in any of the following would enhance the application:

• Good understanding of SoC implementations and models (IBIS models, power models, impedance profiles of power delivery networks)
• Experience of design automation and scripting
• Embedded hardware debug using laboratory test equipment (e.g. oscilloscopes, VNAs)
• Enjoy collaborating across geographies with multiple teams

In Return:

You will gain a deeper understanding of high-performance compute platforms You'll be working alongside other engineering teams, in a friendly supportive environment collaborating with highly motivated, like minded engineers, producing high quality designs incorporating Arm IP. You will enjoy new technical challenges faced when using advancing technologies
