Requirements
  • A Bachelor of Science degree and 10 years of relevant experience are required.
  • Experience with application-specific integrated circuit integration, including one or more of floorplanning, clock and power distribution, global signal planning, and input/output planning, is required.
  • Experience with floorplanning tools, place-and-route flows, and global timing verification flows is required.
Responsibilities
  • Implement complete chip design from netlist to tapeout.
  • Apply physical design and large-chip integration expertise to the design process.
  • Collaborate with front-end engineering teams to understand chip architecture and drive clocking aspects early in the design cycle.
  • Drive clocking construction and solutions for performance, power, and area.
  • Collaborate with cross-functional teams to develop clocking methodologies and best-known methods, streamline physical design work, and create guidelines and checklists.
  • Drive execution and supervise project progress.
  • Communicate and drive the needs of physical design and clocking with multifunctional teams to achieve back-end design goals.
Desired Qualifications
  • Experience with hierarchical design, top-down design, budgeting, timing, and physical convergence.
  • Experience planning, implementing, and analyzing high-speed clock distribution networks from root to leaf.
  • Exposure to balanced-tree, mesh, and forwarded-clock distribution strategies.
  • Ability to use latency, skew, and variation metrics to prevent and solve cross-hierarchy clocking issues.
  • Experience planning and crafting test structures to evaluate clocking functionality and performance after silicon, and engaging with test teams before and after silicon to debug and analyze clocking problems.
  • Experience integrating intellectual property from internal and external vendors and specifying and driving physical-domain intellectual property requirements.
  • Experience with multiple voltage and clock domains, electrostatic discharge solutions, and mixed-signal block integration.
  • Experience with large subsystem designs exceeding 20 million gates and frequencies above 1 GHz using new technologies.
  • Familiarity with process-related design issues, including design for yield and manufacturability, multi-threshold-voltage strategies, and thermal management.
  • A proven track record solving complex physical-design and cross-functional problems, driving results, and directing a team of engineers to innovate and execute designs.
  • Understanding of graphics processing unit architecture and design units.

Simplify's Take

What believers are saying

  • Reuters reported July 30, 2026 revenue of $109.42 billion, up 16.4%.
  • September 2026 Duo launch opens a new premium category and upgrade cycle.
  • IDC expects Apple to capture 40% of foldable shipments by end-2027.

What critics are saying

  • DOJ's March 2024 monopoly case and Epic proceedings threaten App Store economics in 2026.
  • EU General Court's July 2026 ruling keeps Apple trapped under DMA gatekeeper restrictions.
  • Foldable Duo's $1,999 price risks niche adoption and margin pressure against Samsung.

What makes Apple unique

  • Apple's 2026 iPhone Duo and A20 Pro deepen ecosystem lock-in across devices.
  • John Ternus' September 2026 debut signaled faster hardware iteration and tighter AI integration.
  • Apple's custom chips and C2 modem reduce Qualcomm dependence and strengthen margins.

Morgan Stanley sets $360 Apple target on AI innovation and 690M upgrade opportunity

Morgan Stanley analyst Erik Woodring has maintained an overweight rating on Apple with a $360 price target, citing accelerated innovation at the company's September product event. The analyst highlighted Apple's first foldable iPhone, new A20 chips, and enhanced Siri capabilities as signs of stronger momentum under new CEO John Ternus, who recently replaced Tim Cook. Woodring noted that 57% of Apple's installed base—roughly 690 million devices—runs phones older than the iPhone 15 Pro, whilst 87% cannot handle complex Siri AI workloads. With consumers keeping iPhones for over four years, this creates significant upgrade potential. Apple recently reported strong fiscal third-quarter results with revenue of $109.4 billion, up 16% year-over-year, and earnings per share of $2.02, up 29%.

Bank of America cuts Apple price target to $370 after iPhone Duo foldable launch

Bank of America cut its Apple price target to $370 from $380 whilst maintaining a Buy rating, following the iPhone Duo launch under new CEO John Ternus. Analyst Wamsi Mohan cited lower-than-expected iPhone pricing pressuring gross margins amid elevated component costs. The iPhone Duo, Apple's first foldable phone, features a 7.6-inch inner display and 5.4-inch outer display, both supporting Dynamic Island and 120Hz ProMotion. Starting at $1,999, it launches 23 October with pre-orders opening 16 October. Mohan called the foldable the event's standout, noting its potential to reach mainstream audiences through features like dual capture in FaceTime. Citi described it as Apple's biggest new hardware category since the Watch and AirPods.

Apple Watch can record 15 seconds of conversation without both speakers' consent

Apple's new Watch Series 12 features Audio Intelligence capabilities that can record conversations without consent from all parties. The Live Rewind function captures 15 seconds of conversation and converts it to text after the wearer double-presses the Digital Crown. Whilst the watch emits an audible tone to alert nearby people, this doesn't constitute legal consent in 11 US states requiring all-party consent for recordings. The watch processes audio through its S11 chip and nearby iPhone, discarding the original recording after creating text. Siri Recap summarises conversations throughout the day without retaining audio or identifying speakers. The Electronic Frontier Foundation criticised the feature, arguing people lack practical means to consent or decline recording. EFF's Adam Schwartz warned the technology threatens conversational privacy and spontaneity, urging users to reconsider using it out of respect for others.

AT&T CEO dismisses $2K Apple iPhone Duo as 'not new', doubts foldable will break niche status

AT&T CEO John Stankey expressed scepticism about Apple's newly unveiled foldable iPhone Duo, priced at $1,999. Speaking at the Goldman Sachs Communacopia and Technology Conference, Stankey said the device is "not new", noting that Android manufacturers like Samsung and Google have sold foldables for years without broad market success. "What we've seen is that it tends to function more as a specific niche type application as opposed to [being] broadly accepted," Stankey said. He acknowledged Apple could prove him wrong but doubted it would change market dynamics significantly. IDC analyst Francisco Jeronimo estimates foldables represent only about 2.2% of global smartphone sales in 2026. Samsung's Galaxy Z Fold 8 retails for $1,899.

Apple's foldable iPhone Duo starts at $1,999, but will shoppers actually buy it?

Apple unveiled its first foldable iPhone, the iPhone Duo, priced from $1,999 to $3,199. The device features a 7.6-inch inner display and 5.4-inch outer screen, allowing users to run two apps simultaneously. The Duo costs $800 more than Apple's new iPhone 18 Pro. CEO John Ternus called it "the most transformational change to iPhone since the original". Whilst Samsung, Huawei, Google, and Motorola already sell foldables, these devices remain niche. IDC expects global foldable shipments to reach 22.9 million units in 2026, representing just over 2% of the smartphone market. However, analysts believe Apple's entry could shift the landscape. IDC forecasts Apple will ship over 17 million foldable iPhones by 2027, capturing roughly 40% of the global foldables market. The company's large customer base may drive broader adoption of the expensive new format.
