Principal Engineer, Analog Design

The Group:

The charter of ADI’s CSS team is to lead the market in several technology domains with highly differentiated sensing and signal processing solutions. Today these technology areas include Capacitive Sensing, Optical Image Stabilization, Optical sensing, Audio, Capacitance or Laser Driving, and Power, which drive growth in our portable Consumer business. With a goal to deliver sustainable growth the CSS group will present the successful candidate with a great opportunity for continuous career development as part of a highly motivated and supportive team. 

The position :

The group is seeking an experienced Principal Analog IC Design Engineer with deep expertise in power‑management analog design to develop next‑generation PMICs for portable consumer applications. The role includes direct engagement with Tier‑1 OEMs and opportunities for supervisory and mentoring responsibilities.

Responsibilities :

General Responsibilities

• Working within an analog/mixed-signal design team based in our Catania (Italy), Sophia Antipolis (France), Edinburgh (Scotland), and Newbury (England) sites. 

• Definition and architecture development of high-performance mixed signal devices. 

• IC block design, transistor-level circuit design and simulation.  

• Conducting technical presentations to ADI’s internal engineering team and customers. 

• Using recommended design and verification techniques, tools & flows to produce efficient designs which meet all specified functional, power and timing objectives. 

• Successful integration of blocks into larger mixed-signal systems. 

• Supporting other job functions such as layout, lab evaluation and test to ensure successful delivery meeting all requirements. 

• Continuing to improve analog design methodologies consistent with the group’s wider business objectives to reduce time and cost to market. 

Power Design Responsibilities (Core Focus)

• Architect, design, and validate high‑performance power‑management circuits, including:

  • Switching regulators (buck/boost, multi‑mode/multi‑phase, high‑efficiency converters)

  • Low‑dropout regulators (LDOs) for low‑noise and high‑PSRR applications

  • Charge pumps and related switched‑capacitor converter architectures

• Develop closed‑loop control architectures, including compensation strategies, loop‑stability optimization, and transient‑response enhancement.

• Drive innovation in ultra‑low‑power, fast‑transient, and high‑efficiency power designs tailored to demanding portable consumer applications.

• Collaborate closely with system architects to define end‑to‑end power architectures and ensure seamless integration into complex mixed‑signal SoCs.

• Lead power block bring‑up, silicon debug, and optimization to achieve best‑in‑class performance across process, voltage, and temperature variations.

Requirements 

• Electronic Engineering degree with 10+ years’ experience as an analog/mixed signal IC designer. 

• Deep and demonstrable expertise in power‑management circuit design, including switching regulators, LDOs, charge pumps, and associated control‑loop architectures (required core competency, not optional).

• Design experience with circuits such as amplifiers, DACs, ADCs, bandgaps, bias circuits, etc., is an advantage. 

• Strong people leadership, inter-personal, teamwork and communication skills are required to work well within a multi-site cross functional team. 

• The successful candidate will be expected to take a full cell or system ownership role and contribute to the development of new products from architecture selection to implementation and debug. 

• Experience integrating power‑management and analog blocks into complex SoCs or microcontroller systems is a strong advantage.

• Some limited travel should be expected.
