Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you’ll do more than join something — you’ll add something.

Apple Vision Pro is a revolutionary spatial computer that seamlessly blends digital content with your physical space. It will allow us to do the things we love in ways never before possible — all while staying connected to the people around us.


6+ years of industry experiences. Solid EE fundamentals and excellent problem solving skills.

In-depth knowledge in electrical signaling of common high-speed and low-speed I/O interfaces. Protocol level familiarity is a plus.

Strong background in power integrity modeling, simulation, and lab correlation. Familiarity with DC-DC regulator design principles, modeling, and troubleshooting.

Proficiency in SI/PI simulation tools such as Cadence/Sigrity, ADS/Spice, Ansys HFSS, CST, etc. Strong programming background is a plus.

Hands-on experience in hardware characterization, validation, and failure analysis with lab equipment such as VNA, TDR, Oscilloscope, spectrum analyzer, etc. Compliance testing experience on SerDes links is a plus.


Our team is seeking a signal and power integrity (SI/PI) engineer with an outstanding track record in supporting both architectural exploration and product development. The ideal candidate should be highly skilled in all major aspects of SI/PI, including high speed links (e.g. PCIe, USB, DP, MIPI, etc.), low speed buses (e.g. SPMI, SPI, I2C, I2S, SoundWire, etc.), and system power delivery network (PDN) analysis. They will play an integral role in developing innovative technologies and new products.

• System-level SI simulation and design evaluation, including but not limited to PCB stackup, placement/routing, connector and analog/digital IO selection.

• System-level PI simulation and design evaluation, including but not limited to power/ground plane optimization, decoupling cap strategy, transient/frequency-domain noise analysis, EMI mitigation, and noise immunity enhancement.

• Work with cross-functional teams to define I/O and power architecture, as well as specs of silicon, module, and interconnects.

• Work with validation, testing and compliance teams to triage, debug, root cause, and fix SI/PI related issues in product integration.

• Drive the development and deployment of SI/PI focused factory test methodologies and flows.
