IC Designer - Power Management

Apple Inc.; Sunnyvale (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Apple Inc. is seeking an IC design engineer to create transistor-level designs for DC-DC converters and related IPs. You will start with feasibility studies and carry concepts through implementation, simulation, layout, and production in a team-focused environment at Apple.

The role emphasizes optimizing power, area and performance, developing subcell simulations, and defining post-silicon test plans while collaborating across groups to ensure robust ESD-compliant designs.

Qualifications

• BS and a minimum of 3 years of relevant industry experience.
• Experience in optimization of voltage regulator high level architecture and low-level circuits.
• Familiarity with buck, boost, LDOs, bandgaps, bias, comparators, and op-amps.
• Device physics knowledge in regard to analog and power such as transistor operation, optimization, parasitics, and performance.
• Engineers skilled in analog IC design CAD tools and analysis flows for tapeout.
• Experience modeling circuits in Matlab, VerilogA, Python, or C before implementation.
• Validate analog/power designs on a lab bench using spectrum analyzers, oscilloscopes, signal generators, etc.
• Design with detailed testability; write test plans for trim and calibration; collaborate with test engineers.

Responsibilities

• Build concepts to overcome engineering problems in complex power systems.
• Design blocks and documenting design towards formal design reviews.
• Collaborate with mask design to construct layout collaterals.
• Navigate through optimizations of power, area and performance or power IC designs.
• Develop subcell and IP-level simulations to validate designs.
• Define production and bench evaluation plans for post-silicon activities.
• Take bench measurements to validate your own IC designs.
• Review bench and production test results to drive bug fixes.
• Complete designs considering ESD compliance of the circuits.

Job description

Description

In this role, you will be responsible for transistor-level designs of various blocks in ICs including both DC-DC converters and related auxiliary IPs. You may start with early feasibility studies of new concepts/designs and carry them through implementation, simulation, layout, and production. We work in a team environment to build sophisticated power management solutions for Apple products. Collaboration within and outside of our group is an integral part of our work:

• Build concepts to overcome engineering problems in complex power systems.
• Design blocks and documenting design towards formal design reviews.
• Collaborate with mask design to construct layout collaterals.
• Navigate through optimizations of power, area and performance or power IC designs.
• Develop subcell and IP-level simulations to validate designs.
• Define production and bench evaluation plans for post-silicon activities.
• Take bench measurements to validate your own IC designs.
• Review bench and production test results to drive bug fixes.
• Complete designs considering ESD compliance of the circuits.

Minimum Qualifications

• BS and a minimum of 3 years of relevant industry experience.

Preferred Qualifications

• 3+ years of experience in industry for ICs going into production.
• Proven experience with optimization of voltage regulator high level architecture and low-level circuits; knowing which are suitable for given applications.
• Familiarity with buck, boost, LDOs, bandgaps, bias, comparators, and op-amps.
• Versed in the electrical characteristics and physical construction of capacitors and inductors.
• Qualified to review and provide feedback for printed circuit board designs from a power perspective and associated I/O.
• Device physics knowledge in regard to analog and power such as transistor operation, optimization, parasitics, and performance.
• We seek engineers skilled in analog IC design CAD tools and analysis flows to complete the designs for tapeout.
• Experience modeling circuits in Matlab, VerilogA, Python, or C for concepts prior to implementation.
• Validate analog/power designs on a lab bench using spectrum analyzers, oscilloscopes, signal generators, etc.
• Design with detailed testability; write test plans for trim and calibration; collaborate with test engineers.
