Analog Mixed-Signal Modeling Software Engineer

Apple Silicon Engineering is seeking Hardware-minded Software engineers to create innovative tools to design the next generation of Apple's world-leading systems-on-chip (SOCs). Apple's multi-billion-transistor Ax SOCs are the brain of every iPhone and iPad. The Analog Mixed-Signal circuits connect them to the physical world via complex IPs such as SERDES for data communication, PLLs for clock generation, and sensors for measuring physical quantities.

Modeling Software Engineers bring a unique and versatile combination of software and hardware expertise. On their way from the designer's mind to becoming a piece of silicon, circuits take form in software. Modeling Software Engineers develop those software-representations of future hardware and then make them real. This includes both the circuits themselves, and the underlying tools to enable hundreds more designers.

We use modern software design methodology and apply it to Hardware design.

This role develops specialized software tools and simulation platforms that enable the design of analog mixed-signal circuits for Apple's custom silicon chips. You'll combine software engineering expertise with hardware knowledge to build automation frameworks, optimization algorithms, and modeling environments that help circuit designers create the physical interfaces connecting Apple's processors to the real world. The position requires strong programming skills in Python or C++ and involves working on challenging problems at the intersection of software development and hardware design.

Expert-level proficiency in Python and/or C++ Strong background in object-oriented programming (OOP) and software architecture design

Experience with computational geometry, constraint solvers, or optimization algorithms Knowledge of event-driven programming and system-level simulation frameworks Understanding of analog layout principles (matching, shielding, parasitics, DRC/LVS) and EDA tool APIs and file formats (LEF/DEF, GDSII, Open Access) Experience developing web applications (e.g., Flask, React) and designing frontend user interfaces

BS and 10 +years of relevant industry experience
