For over four decades, Cirrus Logic has been propelled by the top engineers in mixed-signal processing. Our rockstar team thrives on solving complex challenges with innovative end-user solutions for the world's top consumer brands. Cirrus Logic is also known for its award-winning culture, which was built on a foundation of inclusion and fairness, meaningful community engagement, and delivering enjoyable employee experiences at every turn. But we couldn’t do it without our extraordinary workforce – and that’s where you come in. Join our team and help us continue to make Cirrus Logic an exceptional place to grow your career!

As a Digital Design Engineer, you will be part of a collaborative, cross‑functional team developing high‑performance mixed‑signal integrated circuits used by leading consumer, industrial, audio, power, and embedded system manufacturers. In this role, you will contribute to the design of system‑on‑chip (SoC) devices, digital signal processing blocks, and digital control logic that interface with high‑performance ADCs, DACs, amplifiers, and power management circuitry, implemented in advanced CMOS technologies. You will play a key role in bringing digital subsystems from concept to production silicon, working closely with analog, verification, layout, and test teams to deliver robust, manufacturable designs.

Responsibilities:

• Design and implement digital subsystems and IP blocks for mixed‑signal ICs from architecture through tape‑out.
• Develop RTL designs using Verilog and support integration into larger SoC environments.
• Design and verify DSP, control, and data‑path logic, including calibration and monitoring state machines.
• Perform functional verification, integration verification, and support UVM‑based verification teams.
• Contribute to behavioral and system modeling of digital and mixed‑signal systems.
• Support post‑silicon validation, characterization, and production test, including lab bring‑up and silicon debug.
• Collaborate across disciplines to ensure correct interaction between digital logic and analog circuitry.
• Participate in design reviews, tape‑out readiness, and root‑cause analysis for silicon or system issues.

Required Knowledge, Skills, and Experience:

• Degree in Electrical Engineering, Computer Engineering, or a related technical field.
• Bachelor’s with 5+ years of relevant digital IC design experience.
• Master’s with 3+ years of relevant experience.
• PhD with 0+ years of relevant experience.
• Strong working knowledge of Verilog RTL design.
• Solid understanding of the digital design flow, including:
• Microarchitecture and RTL development.
• Clock and reset domain crossing.
• Functional verification.
• Timing constraints and synthesis.
• Experience designing and verifying complex state machines and control logic.
• Familiarity with CMOS VLSI design fundamentals.
• Strong analytical, problem‑solving, and communication skills.
• Ability to work effectively in a team‑based, fast‑paced development environment.

Preferred Knowledge, Skills, and Experience:

• Expertise or strong background in Digital Signal Processing (DSP).
• Experience implementing FIR and IIR filters and other signal‑processing algorithms.
• Familiarity with ARM‑based SoCs, microprocessor subsystems, buses, and peripherals.
• Experience with mixed‑signal IC development, including interaction between digital and analog circuitry.
• Exposure to low‑power and high‑performance ASIC design techniques.
• Experience with back‑end flows, including synthesis, place & route, and timing analysis.
• Experience generating test vectors and supporting production or probe test environments.
• Proficiency with MATLAB, Simulink, or similar tools for modeling, algorithm development, and validation.
• Strong lab and silicon validation skills, including silicon debug and characterization.
