Analog Mixed-Signal Modeling Software Engineer

Analog Mixed-Signal Modeling Software Engineer

Cupertino, California, United States Hardware

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.

• Architect and maintain tools, frameworks, and simulation environments within the platform to support analog design workflows
• Design and implement software components for the platform's simulation engine, integrating multiple simulators to support analog/mixed‑signal IP development
• Design and manage data storage architecture for the platform, including schemas, data models, and access layers that support analog/mixed‑signal design data at scale
• Develop web‑based interfaces and visualization tools within the platform to improve designer productivity and workflow transparency
• Partner with analog/mixed‑signal design teams to gather requirements, triage issues, and prioritize platform feature development
• Drive platform deployment and rollout across design teams, and lead adoption efforts through onboarding, documentation, and training

• BS and 10+ years of relevant industry experience

• Expert‑level proficiency in Python and/or C++
• Strong background in object‑oriented programming (OOP) and software architecture design
• Experience with data storage systems, schema design, and database architecture
• Knowledge of event‑driven programming and system‑level simulation frameworks
• Experience developing web applications (e.g., Flask, React) and designing frontend user interfaces
• Experience with CI/CD pipelines, packaging, and deployment (e.g. docker/cloud)
• Strong communication and cross‑functional collaboration skills, with experience partnering with design engineers to gather requirements and drive adoption
