Principal Analog/Mixed-Signal IC Design Engineer

Job Title : Principal Analog/Mixed-Signal IC Design Engineer Location : Edinburgh, Scotland Job Type : Permanent Overview

Our client is a globally recognised leader in high-performance semiconductor solutions, with a strong heritage in precision analog and mixed-signal innovation. They partner with leading technology companies to deliver cutting edge ICs used in high volume consumer and professional audio applications, consistently pushing the boundaries of performance, power efficiency, and integration.

An opportunity to join a high-performing audio design team developing next generation consumer audio ICs. This role focuses on high-performance ADC/DAC design, driving innovation in audio architectures for cutting edge, high volume products. You will take a leading technical role, influencing architecture, design, and validation, while collaborating with global teams and mentoring engineers.

Key Responsibilities

• Lead architecture definition and system level design of high-performance mixed-signal ICs
• Own block-level and transistor-level design, including full simulation and verification
• Drive integration of analog and digital subsystems into complex SoCs
• Present designs and results to internal stakeholders and Tier 1 customers
• Support layout, silicon validation, testing, and product qualification
• Collaborate across multi-site teams to ensure successful product delivery

Requirements

• MSc or PhD in Electrical/Electronic Engineering
• 10+ years' experience in analog/mixed-signal IC design
• Strong expertise in delta sigma ADC/DAC design (end-to-end development) Deep understanding of delta sigma fundamentals and non-idealities (noise shaping, jitter, distortion, stability, etc.)
• Experience with audio amplifiers (Class D), power conversion (buck/boost), and precision analog blocks (bandgap, LDOs, bias)
• Proven track record of first-pass silicon success in high volume production
• Strong experience with Cadence/Spectre and system-level modeling (MATLAB, Simulink, Python or similar)
• Excellent communication skills and ability to work across global teams
• Ability to lead technically without direct authority

Preferred Experience

• Track record of achieving 120dB SNR and best-in-class THD+N
• Background in consumer or professional audio IC design
• Experience with Class D amplifier design
• Understanding of digital audio and DSP concepts (filtering, interpolation/decimation, modulation)
• Passion for audio technology
