Job Description
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 modelling (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
