Senior Mixed-Signal IC Engineer

Company Overview

Novomorphic is a new semiconductor design venture backed by Cadence Design Systems, Welsh Government, and CSA Catapult. We have been established to build critical semiconductor design capability in the UK.

Our focus is advanced integrated circuit and electronic system design, with particular strength in low-power intelligent hardware, edge AI, digital design, analogue and mixed-signal systems, and compound semiconductor technologies.

We are building Novomorphic from the ground up. That means every person who joins us will help shape the company, its technical capability, and its culture. We value technical excellence, ownership, curiosity, collaboration, and practical delivery.

Novomorphic is looking for a Senior Mixed-Signal IC Engineer to create high-performance analogue and mixed-signal integrated circuits for advanced semiconductor systems.

This is a senior technical role for an engineer who can lead complex mixed-signal design work, guide layout activity, support chip bring-up, and mentor other engineers while staying close to detailed circuit implementation.

You will work on high-speed ADCs, DACs, serial data interface paths, PLLs, wide-band amplifiers, biasing, references, regulators, and related analogue and mixed-signal blocks in advanced bulk and SOI CMOS technologies.

As a Senior Mixed-Signal IC Engineer, you will help develop high-performance analogue and mixed-signal IC blocks, with a strong focus on high-speed data converters and supporting signal-chain circuitry.

You will work at architectural and transistor level, using sound analogue fundamentals, careful simulation, layout-aware design practice, lab characterisation insight, and clear technical documentation to deliver robust designs. You will also provide technical leadership across design and layout activities.

Analogue and Mixed-Signal IC Design

• Design and implement high-performance, high-speed core ADC and DAC blocks.
• Develop serial data interface paths and related mixed-signal signal-chain circuitry.
• Design related analogue and mixed-signal blocks such as PLLs, delta-sigma ADCs, DACs, wide-band amplifiers, low-voltage data serialisers, bandgaps, bias circuits, and LDOs.
• Work on advanced bulk and SOI CMOS technologies, including technology nodes down to 22 nm CMOS and beyond.

• Develop high-speed ADCs at both architectural and transistor level.
• Apply strong switched-capacitor design practice, transient-noise analysis, and linearity optimisation techniques.
• Support tuning and calibration approaches for mixed-signal blocks.
• Use best-practice analogue and mixed-signal design tools and flows to produce efficient designs that meet specification.

• Supervise layout activities and provide clear technical direction for sensitive analogue, mixed-signal, high-speed, and matching-critical blocks.
• Contribute to chip bring-up, debugging, lab characterisation, and performance analysis.
• Document design choices, simulation results, layout constraints, test findings, and risks clearly.
• Lead design reviews, mentor engineers, and help build strong mixed-signal design practice across the team.

• High-speed and high-resolution ADCs and DACs for advanced semiconductor systems.
• Mixed-signal interface paths and supporting signal-chain circuitry.
• PLLs, delta-sigma ADCs, wide-band amplifiers, serialisers, bandgaps, bias circuits, LDOs, and related analogue blocks.
• Layout-aware design approaches for high-speed, high-accuracy, matching-critical, and noise-sensitive circuits.
• Practical bring-up, debug, and characterisation knowledge that improves Novomorphic's mixed-signal design capability.

We are looking for a senior mixed-signal Engineer with deep analogue fundamentals, proven high-speed ADC experience, and the ability to lead complex technical work in a commercial semiconductor environment.

You should be comfortable moving between architecture, transistor-level design, simulation, layout constraints, lab characterisation, debugging, and technical communication.

• Master s degree in electronics engineering, or equivalent relevant experience.
• 10+ years  experience as an analogue circuit Engineer.
• Solid fundamentals in analogue and mixed-signal design, including relevant tools and flows.
• Experience leading high-calibre analogue and mixed-signal teams.
• Experience in the design of high-resolution, high-speed ADCs.
• Expertise in switched-capacitor circuits, transient noise, and linearity optimisation.
• Deep understanding of tuning and calibration of mixed-signal blocks.
• Experience in lab characterisation and debugging of mixed-signal blocks.
• Experience with technologies down to 22 nm CMOS and beyond.
• Good knowledge of high-speed layout design and matching.
• Strong written, presentation, and general communication skills.

• Experience with time-interleaved ADCs.
• Proficiency in System Verilog, real-number…
