At Apple, we work every day to craft products that enrich people&rsquo;s lives. If you&rsquo;re passionate about taking on unsolved challenges, we have a great opportunity for a results-oriented and highly motivated RTL Design Engineer. Are you looking to expand your chip design career and challenge yourself in a technical and multi-disciplinary endeavor? If so, this is an exciting position in the world class Apple mixed-signal silicon design team! 
 
This role will build upon your solid foundation in digital logic circuits while introducing mixed signal and analog circuit design and features. You will work with a variety of flows fundamental to modern silicon engineering: modeling and integrating high-performance mixed-signal and analog IPs into high-speed digital circuits. This is an excellent opportunity to gain valuable experience in software methods and analysis, which are increasingly crucial across the semiconductor industry. 
 
As a member of our dynamic team, you will have the exceptional opportunity to help create the next generation of products that will delight and inspire millions of Apple customers every day. You will work to specify, design, verify, and support lab bring-up of sophisticated digital and mixed-signal circuits. 
 
Description 
 
In this job you will be responsible for specifying and/or micro-architecting digital blocks in sophisticated mixed-signal circuits. You will be responsible for RTL coding of blocks specified by you or others. You will also participate in the design verification and bring-up of such blocks by writing meaningful assertions, debugging code, and otherwise interacting with the design verification team. You will contribute to the lab bring-up of those circuits by potentially writing test scripts, analyzing lab data, proposing experiments, etc. 
 
Preferred Qualifications 
 
Proven knowledge of RTL design, Verilog and SystemVerilog 
 
Deep knowledge of front-end tools (Verilog simulators, linters, CDC, RDC, LEQ, UPF) 
 
Low power design methodologies and techniques to reduce dynamic and static IC power 
 
ECO design flows and methodologies 
 
Proven understanding of mixed signal concepts and experience with analog circuit behavioral modeling 
 
Proven knowledge of synthesis, static timing and DFT 
 
Proven knowledge of SystemVerilog assertions, checkers, and other design verification techniques 
 
Knowledge of scripting languages (i.e. Perl, JSON and Python) 
 
Using GenAI tools (e.g., large language models, AI-assisted code generation) to design, validate, and optimize SystemVerilog RTL code 
 
Digital signal processing fundamentals including signal processing concepts 
 
Strong communication and presentation skills 
 
Minimum Qualifications 
 
Bachelors of Science in Electrical Engineering.
