About the job

Requirements
  • Deep understanding of analog mixed-signal design with experience in high-speed serial links.
  • Solid understanding and experience designing analog mixed-signal circuit blocks, including bandgap references, biasing circuits, low-dropout regulators, amplifiers, comparators, switched-capacitor circuits, analog-to-digital converters, digital-to-analog converters, oscillators, and filters.

  • Execute transistor-level implementation and behavioral modeling.
  • Drive mask design to implement layout views of designs.
  • Work with system-on-chip teams to deliver intellectual-property views and ensure they meet quality standards.
  • Communicate progress and discuss new ideas with peers and management.
Desired Qualifications
  • Experience with timing-closure concepts and related industry tools such as Nanotime and PrimeTime.
  • Experience testing high-speed serial input/output, debugging, and performing data analysis.
  • Knowledge of common high-speed SerDes protocols such as PCI Express, USB, DisplayPort, and M-PHY.

Simplify's Take

What believers are saying

  • Apple reported $109.4 billion fiscal Q3 2026 revenue, its strongest June quarter ever.
  • India revenue topped $10 billion in fiscal 2026, despite softer smartphone shipments.
  • Reuters on September 9, 2026 said Apple targets 40% of the foldable niche by 2027.

What critics are saying

  • Apple faces India CCPA scrutiny since September 15, 2026 over iOS 18 repair costs.
  • OpenAI’s July 2026 countersuit and 400 ex-Apple hires intensify talent leakage and trade-secret risk.
  • A $1,999 Duo prices out mainstream buyers; Samsung and Android foldables already dominate.

What makes Apple unique

  • John Ternus launched iPhone Duo September 9, 2026; Apple finally joined foldables.
  • Apple’s C2 modem and A20 Pro chips reduce Qualcomm dependence and tighten integration.
  • iOS 27 deepens Siri across messages, photos, and email with privacy-first positioning.

Apple's iPhone 18 Pro goes on sale with prices up to $3,000 and new foldable Duo model

Apple's iPhone 18 Pro and Pro Max went on sale Friday, with customers queuing at stores worldwide. The devices start at $1,199 and $1,299 respectively, featuring a reimagined camera with DSLR-like aperture for improved low-light performance. The launch coincides with the release of Apple's foldable iPhone Duo, priced up to $3,000. The new phones can detect AI-generated photos by creating unalterable Reference Images alongside edited versions. New CEO John Ternus, who recently succeeded Tim Cook, visited Apple's Fifth Avenue flagship store in New York, greeting customers and signing autographs. The phones debut the upgraded Siri AI, powered by Google Gemini models, which can access information across messages, photos and emails, and draft communications.

Apple eyes $450 by 2027 on Siri AI bets despite memory cost squeeze

Apple reported $109.42 billion in fiscal Q3 revenue, marking its ninth consecutive earnings-per-share beat. CEO Tim Cook said iPhone growth has been running at 22% recently. Shares are up 23.19% year-to-date but trade below levels some analysts believe a full Siri AI cycle could justify. The stock currently sits at $334.31, with Wall Street's consensus target at $325.66. One analyst projects a base case of $378.88 and a bull case of $431.31, suggesting potential upside. However, Cook warned of significant memory price increases and supply constraints expected in the September quarter across iPhone, Mac, and iPad products. Gross margin in Q3 received a roughly 2-percentage-point boost from one-time tariff refunds. The company faces ongoing margin pressure concerns heading into 2027.

Apple's India iPhone prices surge 44% above US rates, risking $10B market growth

Apple unveiled its iPhone Duo foldable smartphone and iPhone 18 Pro models, marking a significant redesign. However, the company has substantially increased prices in India, potentially alienating customers in this key growth market. Apple's India revenue exceeded $10 billion in fiscal year 2026, up from $9 billion the previous year. This growth came despite a 7.9% decline in overall Indian smartphone shipments. The price increases in India are considerably steeper than in the US. The iPhone 18 Pro base model costs INR 164,900 ($1,725), 44% more than its US price. The iPhone 17 saw a 21% price increase to $1,045, whilst the cheapest model, iPhone 17e, now costs $836. These hikes stem from import duties and component taxes. With the Indian smartphone market showing signs of weakness, the steep price increases could challenge Apple's growth trajectory in the region.

Nvidia, Fortinet, Alphabet, Microsoft and Apple positioned to weather higher interest rates

The US Federal Reserve raised interest rates by 25 basis points yesterday, bringing the federal funds target range to 3.75%–4.00%. This monetary tightening could pressure economic growth and compress valuations in the technology sector. However, companies with strong balance sheets, robust cash flow, and minimal dependence on external financing are better positioned to weather higher rates. Five tech stocks stand out in this regard: Nvidia, Fortinet, Alphabet, Microsoft, and Apple. Nvidia generated $24.1 billion in operating cash flow in Q2 and held roughly $56.6 billion in cash and marketable debt securities. Fortinet produced $966 million in free cash flow on $2.05 billion of Q2 revenue. Alphabet ended Q2 with approximately $242.5 billion in cash and equivalents.

OpenAI denies Apple trade secret theft, calls dispute 'a mess of Apple's own making

OpenAI has denied Apple's allegations of trade secret theft in a US District Court filing, calling the dispute "a mess of Apple's own making". Apple sued OpenAI and two former employees in July, accusing them of misappropriating trade secrets related to hardware design and manufacturing. OpenAI argued that California law permits employees to move freely between employers. Court filings reveal OpenAI has hired roughly 400 former Apple employees for its hardware initiative. The lawsuit marks an escalation between the companies, who partnered two years ago to integrate ChatGPT into Siri. That relationship has since deteriorated as Apple shifted towards using Google's Gemini to power its redesigned Siri instead of deepening ties with OpenAI.
