Description For System Signal Integrity Engineer

Join Apple's Mac organization as a System Signal Integrity Engineer where you'll be at the forefront of hardware innovation. This role focuses on system-level signal integrity design, analysis, and validation for Mac and Accessory products development, from conception to production. You'll work with cutting-edge technology, applying your expertise in high-speed SerDes, parallel bus, and single-ended signaling.

The position offers an opportunity to work with state-of-the-art tools and technologies, including 2.5D tools (PowerSI, SIWave, Sentinel-PI, nSys), 3D Full wave (HFSS, nWave), and quasi-static tools (Q3D, nApex). You'll be involved in designing custom connectors, cables, and supporting factory builds while ensuring electrical compliance.

As a key member of the hardware team, you'll leverage your knowledge of various industry SerDes standards (USB, DisplayPort, HDMI, MIPI, etc.) and parallel bus interfaces. The role requires expertise in measurement techniques using frequency and time domain tools, along with programming skills in Matlab/Python/PERL.

This is an excellent opportunity for an experienced professional to make a significant impact on Apple's flagship Mac products, working in a collaborative environment that values innovation and technical excellence. The role combines hands-on technical work with strategic thinking, requiring both deep technical knowledge and strong communication skills.

Count Numbers with Unique Digits

Data Structures & AlgorithmsMedium

Given an integer n, return the count of all numbers with unique digits, x, where 0 <= x < 10^n. For example: Input: n = 2 Output: 91 Explanation: The answer should be the total numbers in the range of 0 <= x < 100, excluding 11,22,33,44,55,66,77,88,99 Input: n = 0 Output: 1

How would you design a platform architecture for a rapidly growing social media company to ensure scalability, reliability, performance, security, and cost-effectiveness?

System DesignMedium

Let's discuss platform architecture. Imagine you are tasked with designing a platform for a rapidly growing social media company. This platform needs to handle millions of users, support various media types (images, videos, text), and provide real-time updates. Consider the following: Scalability: How would you design the architecture to ensure it can handle increasing user traffic and data volume? Discuss specific technologies and strategies (e.g., load balancing, caching, sharding). Reliability: What measures would you take to ensure the platform remains available and fault-tolerant? Consider redundancy, monitoring, and disaster recovery. Performance: How would you optimize the platform for speed and responsiveness? Address concerns like database performance, content delivery, and API design. Security: What security considerations would you prioritize to protect user data and prevent attacks? Think about authentication, authorization, encryption, and vulnerability management. Cost: How would you balance performance, scalability, and reliability with cost-effectiveness? Discuss trade-offs and potential cost optimization strategies. Provide a high-level overview of your proposed architecture, including key components, technologies, and design principles. Explain your reasoning behind each choice and how it contributes to the overall goals of the platform. For example, would you choose a microservices architecture or a monolithic architecture? What type of database would you use and why? How would you handle real-time updates and notifications? What CDNs would you use?
